Menu

Sons of Liberty Gun Works and Brownells have teamed up to bring you this rugged and ready AR-15 16” M4-76 Upper Receiver

The M4-76 upper receiver has a 16” barrel made from 4150 chrome moly vanadium that has been high pressure tested and magnetic particle tested.  The barrel has a Mid-Length gas system, a 1-7 rate of twist, and a muzzle threaded ½-28.

The M4-76 upper receiver uses the 15” SOLGW M76 Wedge Lock Rail which accepts M-LOK attachments and features a steel barrel nut.

The M4-76 16” Upper Receiver comes to you without a bolt carrier group, charging handle, or muzzle device knowing that for many customers these are some of the most swapped out parts of an upper receiver so we want to save you money while allowing you to pick out the exact components you like.

Sons of Liberty Gun Works believes in their products and backs them up with a lifetime warranty. SOLGW builds their products to be used hard and go into harm’s way and will not let you down.
