We absolutely Love this Barrel!

All SMG variants of the CAR-15 family tried before 1967 were 10 inches long.. And for some weird reason it's the hardest barrel length to find.

A Retro Rifle exclusive, this 10 inch barrel is a fine choice for all early CAR-15 models (XM177E1, CAR-15, Survival Rifle, early prototypes, etc)

It can also be used as a substitute for M4 Commando builds where you want the muzzle device to start immediately after the Front Sight Base (FSB) - or for anyone that just prefers a 10" barrel on their CQB rifle.

Nitride finish provides extended barrel life, making this a good choice for high round count use. It's also the best finish for harsh environments or for folks that just hate to clean barrels.

Why choose this barrel?

  • It's 10 inches and can be used with both a FSB or low pro block. This is a VERY hard to find barrel length.
  • Nitride finish is the toughest available, yet looks like a US Military finish

* Note: This barrel is VERY HARD and will last longer than many others.. making this an excellent choice for Full Auto use. Due to this, if you will be pinning a FSB on this barrel we recommend either you upgrade to letting us do the FSB pin install, or use Bose Cobalt bits for drilling your tapper pin holes.
