Quick Summary

The M16A3 was an M16A2 variant featuring full-automatic fire instead of a three-shot burst. 922R compliance focuses on imported parts for firearms assembled in the US, not exports. For a suppressed 16-inch mid-length 5.56 SPR with 77-grain ammo, an H2 buffer is recommended. Stainless steel barrels excel at precision, while chrome-lined barrels offer greater durability for combat.

Frequently Asked Questions

What is the difference between an M16A3 and an M16A2?

The M16A3 was essentially an M16A2 with the key difference being its full-automatic firing mode, whereas the M16A2 was limited to three-shot bursts. Functionally, they were otherwise very similar.

How does 922R compliance work for firearms in the US?

922R compliance specifically regulates the number of imported parts allowed in a firearm assembled in the United States. It does not pertain to firearms being exported out of the country.

What buffer weight is recommended for a suppressed 16-inch mid-length 5.56 SPR?

For a 16-inch mid-length gas 5.56 SPR shooting suppressed with 77-grain ammunition, an H2 buffer is generally recommended to help manage recoil and ensure proper cycling.

Are stainless steel barrels better than chrome-lined barrels?

Stainless steel barrels are ideal for precision shooting and achieving tight groups. Chrome-lined or cold hammer-forged barrels are preferred for combat applications and longevity due to their durability.

What is the difference between direct impingement and gas piston systems?

The M16 system uses an internal piston, not direct impingement. True direct impingement involves a tube hitting the bolt face. External piston systems, located outside the bolt carrier, can offer benefits for short-barreled rifles.
