Colt XM177E2 / GAU-5A/A / CAR-15 / model 629, 630 Commando / US Air Force (1967-1970)
Brand : Retro Rifles
In 1966, the Army decided it wanted a slightly longer barreled version of the XM177E1, 11.5 inches instead of the original 10 inch barrel.
Wildly popular with Special Forces, SOG, LRRP teams, SEAL's, CIA and foreign Special Forces both in Vietnam, and elsewhere in the world. British and Australian SAS are particularly famous for using this version.
After 1974 the 4.25" Moderator was dropped in favor of the A1 Birdcage on further Commando models until the early 1980's.

This is a highly authentic reproduction of the Colt XM177E2 or GAU-5A
It is a common misconception that the XM177E2 used a Delta Ring during the Vietnam War. We have researched this extensively and do not believe the Delta Ring was used until the early 80's on any Colt. "There are rumors to suggest the Delta ring was actually developed sometime in the mid-70's (1973-75) - but all photographic evidence seems to point to 1982 for first official use.
* Notes on Options
- Slick Side - Air Force GAU-5A
- A1 with Tear Drop Forward Assist, Army XM177E2 (1965-1983).
- C7 is an A1 receiver with an Shell Deflector.. best choice for Left Hand Shooters, not a NoDak (1983-1995)
* Note: C7's were never official Army issue. Only Special Forces and the Canadians (C7/C8) used this transitional receiver style. Walks and talks like an A1 but doesn't hit you in the face when shooting southpaw.
From 1960-1965/66 all M16 variants were delivered with Chrome BCG's. 1967/68 on-wards the finish was changed to Mag Phosphate, as it is to this day. So it's entirely possible either was used, in anything, after 1967. Choose Chrome or Phosphate - no cost difference.. or get it without a BCG if you don't need one.
- 4.25 inch Moderator is technically correct for all models 1967-1974
- A1 Birdcage is "officially" for Commando Models from 1974-1983. But this was also a rare configuration performed in the field during the Vietnam War to further reduce overall length.
