Cmmg Ar-15 Echo Conversion Kit 22lr. Just swap this drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR. Ships with 25rd 22LR magazine. For best performance use a round style hammer as notched hammers can cause function issues and 36 grain plated nose bullets have proven to be the best choice for function. NOTE: Since .223 WYLDE is NOT a mil-spec chamber, CMMG cannot guarantee fit or function with our 22LR conversion kits

Wmd Guns Ar-15 5.56 Nickel Boron Bolt Carrier Groups. Each WMD bolt-and-carrier set is precisely machined from high-grade steel alloy to government M16 specs, then given WMD’s proprietary NiB-X nickel boron coating that results in a super-smooth, harder-than-chrome surface. NiB-X reduces friction to the bare minimum and is impervious to corrosion and abrasion. The slick finish also keeps carbon from adhering, so clean up is much faster and easier than with standard parts. Ideal choice for 3-gun competitor sand other high-volume shooters.

Smith Enterprise M16 Chrome Match Bolt Carrier Assembly. True, match-spec bolt carriers increase cycling efficiency for greater dependability and less chance of malfunction. Machined to military specs, hardened and heat treated, then hard-chrome plated for a much lower co-efficient of friction between the upper receiver and carrier. Inside surfaces of bolt recess are polished and also hard-chromed for a better gas seal and less carbon build-up. Includes hard-chromed gas key and stainless steel screws.
J P Enterprises 308 Ar Enhanced Bolt Completion Group. Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. SAE 9310 steel has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds. This is the same steel used in the transmission gears of Formula 1 race cars, so it’s ideal for high-impact, high-heat applications like sustained full-auto fire. Meticulously machined radiuses on all 90-degree corners on the locking lugs help distribute impact force evenly and further red
Odin Works Ar 308 Bolt Carrier Group. When AR owners step up into the AR 308 world to shoot today’s popular short-action cartridges like the .308 Win. Or the 6.5 Creedmoor, there can be a bit of a learning curve that isn’t present in the AR-15 world.

This ODIN Works AR 308 Bolt-Carrier Group is designed to work with any cartridge designed around the .308 Win. case head, and one of the highlighted options on this BCG is the use of a smaller-diameter firing pin and firing-pin hole that aids in the performance of these higher-pressure cartridges. The BCG works in
