AT3 Black Nitride BCG + Breek Warhammer AR-15 Charging Handle

The AT3 Tactical BCG and Breek Warhammer Charging Handle pair perfectly to complete your AR-15 upper receiver. Save on this bundle with a standing discount on our BCG, with one of the most popular charging handles in our store! Choose the lever size of the Breek Warhammer that fits you best to improve your rifle’s ergonomics, with reliability you can trust with the AT3 nitride bolt carrier group.

This kit is great for finishing out an upper build, and you can save even more by bundling our Upper with M-LOK handguard, or Upper with Quad Rail. Be sure to look out for a barrel as well, whether chambered in 5.56 or .223, .300 Blackout, or .350 Legend. These three calibers share the same 5.56 bolt face, which means the AT3 BCG can be used for a variety of builds.

AT3 Tactical Black Nitride Bolt Carrier Group – 5.56, .300 Blackout, and .350 Legend Compatible

Getting a high quality bolt carrier group (BCG) that runs well in your rifle is absolutely critical.  AT3 offers this BCG with a black nitride finish, which reduces friction and increases surface hardness for a lifetime of use.  The carrier itself features a full mass M16 cut for the best possible reliability in your AR-15 build.

BCG Made in the USA

The bolt itself features shot-peened 9310 steel construction, which is Magnetic Particle Inspected (MPI) to ensure there are no hidden cracks or stress points.  The bolt also has a chrome-plated firing pin, and a mil-spec o-ring extractor already installed to ensure reliable extraction of spent brass.

AT3 sources these nitride BCGs from one of the largest suppliers of bolts and carriers in the firearms industry.  When you buy a BCG from us, you’re getting a high-quality product that’s made in the USA, that’s trusted by dozens of brands and manufacturers, and we back every one with our AT3 lifetime warranty.

Breek Arms Warhammer AR-15 Charging Handle – Standard and Micro Levers in All Colors

If you’re looking for a charging handle upgrade that’s above and beyond the mil-spec, with features that rival the big brands, at a price that really can’t be beaten?  Look no further than the Warhammer from Breek Arms.  Not only does it make your AR15 truly ambidextrous, but the Warhammer also has thin, deep-set handles to ensure it doesn’t interfere with optics or backup sights, making for an even slicker experience than other handles out there.

Haven't got to run them yet, but I have a warhammer already and love it. Always a pleasure ordering from AT3

Dravvis Sanders
Great combo

The Warhammer is great product feels very solid but very light at the same time love the gas directing design for suppressed weapons and very easy to pull in both sides. BCG had better staking than my current one , good finish, magnetic particle inspected, super slick, full auto design... Super smooth no complaints

Zach Neff
Worked well

The charging handle is a little hard to manually push forward but I’m sure that will change after some time. The bcg works well now but jammed a couple times the first few rounds down range. Once everything was worked over, everything worked like a charm

Curtis Ratcliff

Seems to operate well, I have had no problems!
