How To Change Barrel On Remington 700

A Survey of Custom Remington 700 Custom Deportment to Stimulate Your Precision Build Muscle

The get-go edifice cake of a custom bolt gun is the action. It represents both the skeleton and the heart, holding all the pieces together and circulating ammunition and empty cases through the precision platform.

With more than than an estimated half-dozen million in apportionment, no other activity on the market comes close to the popularity of the Remington 700. Aftermarket back up for the 700 is massive — and that alone is a skillful reason to build a custom bolt gun on the platform.

For the builder on a budget who already owns a Remington 700 action, dropping a few hundred dollars on trueing and/or blueprinting might make sense.

But, if pure operation is the goal, a custom 700-fashion clone will provide accuracy and reliability-enhancing features that Remington's engineers couldn't have imagined when they released the first 700 model in 1962.

Don't let the proper name fool you, though. The word clone implies a shared sameness with the stock Remington activeness, but these are next-generation, premium-quality evolutions that merely share the same dimensions every bit their forefather.

GETTING STARTED

Given its massive popularity, it's fair to call the 700 activeness the bolt-gun equivalent of the AR-15. At that place are tons of parts bachelor, the blueprints are practically in the public domain, and chances are good that within 15 minutes of your electric current location, there'southward a guy with a beard, a lathe, and a six-week excess of Remington 700 barreling jobs sitting on his workbench.

Simply while the AR-15 analogy is shut, information technology'south not perfect. Despite widespread parts compatibility, information technology's typical to await 2 parts made by two different companies to require some level of plumbing equipment for height functioning. As Russ Rosene of Stiller's Precision Actions told us, "The only thing 'drop in' on a bolt activity rifle is ammo — and that'south only 95-pct truthful."

It's our intention to call out the features that prepare 8 popular 700-mode action clones apart from each other, while pointing out some of the pitfalls you lot might run into on your walk through the thorny jungle of custom precision rifle building. If this is your kickoff build, we urge you to go over your complete build sheet with an accomplished 700 builder or gunsmith.

BUSINESS TIME

For loftier operation, applied precision shooting — roughly meaning ane,000-1000 headshots on control — a good action is machined true and has a few jobs; loading a cartridge, igniting the primer, containing the chamber pressure level as the bullet does its thing, extracting the spent brass and ejecting it.

It likewise needs to provide an earthquake-proof platform for an optic, resist movement in the stock under recoil, and enable the bolt to move as frictionlessly in the receiver as we imagine Maria Sharapova's sweaty thighs motility confronting each other on a hot day at Wimbledon. As yous might expect with $ane,500 actions, each of the custom actions in our roundup largely excel in these areas. Where they differ is in the fashion they practice and so.

We linked upwards with a handful of respected military and competition shooters, and their insights inform a bully deal of this article: Caylen Wojcik from Magpul CORE and a prior service USMC scout sniper; Robby Johnson, from Q, LLC, a onetime U.Southward. Army Ranger and standout member of the Ground forces Marksmanship Unit of measurement; Lindsay Bunch also of Q, LLC; and erstwhile Special Operations Command sniper, Norm Houle, 4-time National Loftier Power champ and 2015 National Palma Squad member; and Greg Hamilton, a fearsome PRS competitor and the guy who works on the PROOF Research shooting team'south guns.

In talking with all of these guys, we assembled a master list of features that you should be enlightened of when shopping for a 700 clone. The importance of each varied within the grouping, so y'all'll take to consider how y'all program to use your gun and rank them accordingly.

THE Nuts

The 700 is a rotating commodities activeness. The lugs lock into the receiver and provide the backstop for the cartridge as the expanding gasses develop the tens of thousands of pounds of pressure needed to push the bullet out of the barrel. The back of the bolt lugs should mate well with the front of the action'southward locking recesses. Skillful bolt lock-up provides consequent cartridge headspace and an "airtight" fit between the lugs and the lug seats; important if you want to keep your skin attached to your confront. A poorly plumbing equipment bolt is a path to a cleaved bolt, and all the pain that comes with it.

Bolt-action guys think ammo factories are adept for providing two things, ammo for their semi-autos and a stream of ready-to-fireform brass for their Ackley cartridges. "Most people in PRS aren't shooting manufacturing plant ammunition," Wojcik says, "Merely if yous exercise have a encephalon fart in your loading process, you want to brand sure the action is strong enough that you're not going to eat a bolt."

Whether a result of uneven wear leading to broken parts or an overpressure event, commodities action shooters are always concerned with safety. In the result of a accident upwardly, action makers want the bolt to stay in bombardment, versus shooting out the back of the action into the shooter's confront. Containing all the parts of the gun in an overpressure event is a product of strong materials and smart engineering. Generally, 700 actions can vent gas through bolt's firing pivot channel, a lug raceway, and out the ejection port or magwell. You might also observe minor holes in the sides of some receivers; these strategically placed ports are meant to vent gases in a relatively prophylactic direction in the event of a pierced primer, and may even aid in the outcome of a full-on detonation.

The butt interface in all the 700 actions presented is one 1⁄sixteen-inch with xvi, 18, or 20 threads per inch. xvi TPI is the standard Remington thread pattern; 20 TPI is the Savage thread pitch. A one ane⁄16-inch twenty TPI threaded action can use small shank Vicious barrels. With a Vicious small shank and a barrel nut, you tin install a pre-fit (aka pre-chambered) barrel with a Barbarous barrel nut wrench and a vise. You set the headspace past hand tightening the butt on a go-approximate or a spent cartridge and so lock information technology in by torqueing the barrel nut. You lot might hear this mashup called a Ramage (or Remage) setup. If yous get with the Ramage 20 TPI, you tin still do a traditional barrel installation with a shoulder if the butt nut setup scares you.

With practise, a Ramage barrel tin can be swapped in 20 minutes. If your action has an interchangeable commodities head, y'all tin even change calibers —bouncing, for example, between 6mm Creedmoor for mid-range and 7mm SAUM for long-range competition.

Commodities faces are more often than not measured across the base of the root cartridge it's meant to hold. A .470 bolt confront is sized for .308 Winchester and similar-sized cases; information technology's known as a standard bolt confront. Other popular bolt face sizes are .223 (.384), short magnum (.540), and Lapua (.585). Some makers volition requite you an verbal measurement, but about call out the parent of the cartridge family with which their action is compatible.

Variations in bolt face sizes betwixt manufacturers for a given cartridge are one of the special ingredients in an action recipe. Adding a few thousandths can increment compatibility with more cartridges; tightening things can increment functioning while perchance leading to reliability issues.

In the original Remington blueprint, the bolt terminate is role of the trigger. If the commodities release lever gets muddy or frozen, it tin can stick in the unlocked position omitting the bolt stop. Farther, when the bolt hits at the limit of its travel, all that energy is going into the rear trigger pin — and can cause consistency issues with your trigger pull.All of our custom actions have forgone the original blueprint for some variation of an external commodities terminate.

Non all external bolt stops are created equal, though. The 700 action in the USMC M40A3 sniper has an external bolt stop using coil pins. The way the slot is engineered, all the free energy comes dorsum on the pins and they tin exist torn out of the action.

"In that location's an incredible amount of force on that bolt cease," says Wojcik, "I ripped a bolt out of a gun while teaching a Marine Corps sniper class in 2002. I hit the span of my nose and saw stars." A bolt end design using some sort of wide surface interface that focuses the violence of the commodities stopping on the action wall, instead of the pin securing the stop, should forestall knocking yourself out.

The two reigning standards for tactical magazines are the single-stack AICS pattern magazine and the double-stack AIAW pattern magazine. Magazine compatibility is determined past the cut on the activity bottom. An activeness cut for AW mags will by and large run AICS mags as well, but an AICS action will only run AICS-type mags. The advantage to the double-stack AIAW mags is that they're nigh half the height of an AICS mag of the aforementioned capacity and can exist topped off through the ejection port.

Trigger hangers let you swap triggers using screws instead of punches. Handy for mid-match repairs. Yous may need to make room in your stock for the wider hanger base, though.

An integral recoil lug is a benefit for the guy installing it, mitigating the demand to line up and concord the lug in place during butt installation. An integral lug besides means fewer facets to machine and worry well-nigh squaring upwards. On the flip side, the holes drilled into the action to concord a dowelled lug in place can weaken the action in one of the most critical areas, just beneath the chamber. A costless, unpinned lug might be better than a dowelled lug for strength, but clocking 1 during the barrel install is a PITA.

Commodities handles can snap off. It doesn't happen often, merely banging on one to free a bolt that's latched on to a stuck round can break it off. Some bolt handles are integral, pregnant the bolt body and bolt handle base are carved from i piece of steel. Nigh are welded in place. None in our roundup are brazed or soldered; both of those processes should be avoided.

The ejectors in these deportment are either an AR style bound plunger or a mechanical affair. The plunger is a reliable system, sending brass on its manner based on jump pressure. In mechanical systems, the stationary ejector is on the receiver wall and the cartridge base of operations hits it as the commodities is retracted, letting you toss brass or only dribble it out. Nice, if you like to collect your empties, rather than go search for them.

The original Remington C-clench extractor is absent in all our custom actions. That might be a inkling. Sliding extractors grab the cartridge rim with a minor sliding claw, M16 and mini16 extractors operate equally tensioned levers like the extractor in an AR, the Mauser-style in the Mausingfield is a huge claw with enough surface area that information technology may exist able to pry the world from its orbit, and the behemothic M16 manner extractor in the Tempest tin exist adapted with a little curve, similar to a 1911 extractor.

Controlled feed means the rounds are fed from the magazine upward the bolt confront, under the extractor claw, and carried into the chamber. Traditional push feed has the circular getting knocked forward from the mag and shoved into the sleeping accommodation with the extractor snapping over the case rim equally information technology bottoms out. Both work, and at that place is scant bear witness that one has an advantage over the other.

An integrated runway bridges the top of the action, increasing rigidity. But information technology limits you to a single ascension, or requires the use of graduated ascension optic mounts from the likes of Spuhr and LaRue. All the not-integrated rails feature stout recoil/indexing pins (or a taper fit as seen on the Mausingfield) to go along them in identify. Most of yous shooting standard cartridges volition exist looking for a xx MOA rise on the action or in a mount. Take note, some actions can take an extended rail for larger optics or more than flexibility in placement.

We've tortured y'all enough with generalities, and so let's get to the metal. Nosotros'll call out a few more key features equally they apply in the following product notes.

NOTES:
BAT applies its considerable benchrest knowhow to the practical scene with the integral runway VR. Tightest (in a good way) experience of the group. The sliding extractor is built into the recoil lug for forcefulness. Firing pivot is removable without tools thanks to a slick bayonet design — rotate the commodities shroud an eighth of a turn and it pops out. Slick bolt motion on axis; steep lever angle and small knob brand it unlikely that yous'll demark the activeness with upward pressure. Wide recoil lug; might need some fitting on a few stocks, namely older AIs. BAT makes a narrower lugged version exclusively for Wolf Precision called the BTA. Check out the Wolf'southward Interchangeable Bedroom Barrel Organisation for the VR and BTA. The spiral-in sleeping accommodation means you can go your gun re-barreled in days instead of weeks.

Impact Precision is co-endemic by Tate Streater, Robin Smith and Wade Stuteville. Stuteville was 1 of the guys that made Surgeon Rifles a household name in precision shooting. The 737R is created and toleranced as a single part; nothing needs fitting, including a replacement butt. Affect's replacement barrels are fully pre-fit and screw on without a barrel nut. Bolt finish is completely reinforced and protected in a protruding shroud. The finish bears on the wall of the action, not the pin. Short lever and steep angle puts it closer to your fingertips. The commodities is fluted on top where it can move debris, flat on the bottom for smoothen contact.

Three-lug makes for larger, more than durable bolt body. Increased diameter bolt caput has more area to grab rounds from the AW magazine. In terms of condom, GAP says its action is 40- to fifty-percent stronger than the original 700 action.

We've seen accomplished firearm engineers marvel at ARC's ingenuity and execution. Cruel modest shank threads for a Ramage setup. Swap the bolt head for caliber changes. Beveled surface, swappable scope base is bombproof; many MOA options available. Mauser-style extractor is like having a grizzly paw working for you lot. Smooth operation stands out fifty-fifty among this crowd of outperformers. ARC says its toroidal lugs give a lap fit without lapping. Easy teardown with an Allen wrench. Cartridge has no contact with extractor (or ejector) while chambered, so nothing interferes with it sitting true to the bolt face up. Bolt body and handle root made from a forging; bolt knob reverse threaded for unreal durability. Bummer — doesn't like Magpul Ac mags.

NOTES:
The Spectre is a tank. Perchance a animal. Somehow information technology imparts a impenetrable feeling while it'southward amongst the lightest in the group. Perhaps information technology's the octagonal shape. (The activeness is machined, non turned.) Will fit many chassis; some stocks might demand inletting for the corners. Action comes with a 20 MOA integral rail; no other options. Black nitride end is very durable. Partial fluting saves weight/ejects trash on top, slick on the bottom for smoothness. The long bolt handle did feel a little bindy with hurried bolt operation. Cutting for operation with AICS and AW mags. Rem standard two-pin trigger connector for wide 700 trigger compatibility. Vents overpressure down left side raceway, shroud directs boom away from shooter. According to a survey past the Precisionrifleblog.com, Stiller is one of the top v picks of the pinnacle 100 PRS shooters.
