Note: This barreled upper receiver assembly has a barrel length under 16” and is therefore subject to all NFA rules and regulations. Know your local laws before purchasing.

The Sons of Liberty Gun Works M4-EXO2 is a great entry level AR-15 barreled upper receiver. It features a 9” barrel machined from 4150 chrome moly vanadium steel and QPQ Nitride finished inside and out for optimal durability and wear resistance. The pistol length gas system ensures reliable function in all conditions with minimal recoil. The M4-EX02 .300 Blackout barrel and pistol length gas system are protected by the EXO2 free float handguard with M-LOK slots for the attachment of accessories, making it an extremely customizable upper. The EXO-2 handguard securely attaches to the M4 flat top upper receiver with a steel barrel nut that prevents rotation or loosening of the handguard. The upper receiver is made from 7075-T6 aluminum Cerra forgings and type III hard coat anodized finish in black. The upper receiver comes with the forward assist and dust cover assembled but does not come with a BCG or charging handle. The inside of the receiver has a dry film lube applied to decrease friction with the bolt carrier for smooth function.
