Please Note: Given the current demand for this product and supply shortages, your order may ship with a black hammer and trigger or a stainless steel hammer and trigger.
Ultra-light with hyper accuracy, this upgraded M4-type AR15 build kit is setting a new standard. Tucked under a lightweight free-float M-Lok handguard is a Government barrel forged from mil-spec 4150 Chromoly Vanadium with a 1:8 twist. Throw some 62-grain M193 or 77-grain Match Kings down the muzzle, and you’ll put one hole atop another at 100 yards for sub-MOA performance.
All things remain mil-spec for utter reliability: A forged Picatinny flattop receiver with M4 feed ramps keeps everything cycling smoothly in tandem with an M16 chrome-lined BCG. Carbine gas ensures any loads will cycle quickly and smoothly, and a mil-spec parts kit with Carbine buffer and M4-type buttstock finishes off the kit.
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.
Here's the beginner's guide to 80% lowers.

Manufactured to DPMS and finished with a a superior quality parkerized finish that protects against corrosion and heat, our BCG will not let you down. To ensure that it will provide superior performance in your AR-10, each bolt carrier group undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI).

➲ Standard AR-10 Charging Handle
A central component of your AR-10, the charging handle not only assists in chambering a round, but is your main tool to clear a round that won’t eject cleanly. The 7075-T6 aluminum design results in a rugged and capable charging handle for your AR-10. With lightweight aluminum construction and a traditional snag-free latch design, this charging handle provides superior function and reliability.

With its low profile this gas block allows it to fit under the most ergonomically designed handguards and rails on the market.

KIT notice as of March 1st 2020.
All build kits are subject to change slightly in this time of EXTREME demand. We are not currently able to fill specific spec requests.. the kit parts will fall into the general specs above but items such as stocks, handguards, and muzzle devices are changing daily.
Due to extreme order volume the handguard may NOT be a quad rail.. it will be either a quad rail, mlok or keymod depending on availability. You can still attach rail sections to mlok and keymod for your accessories
