This "Pencil" profile barrel is the same size and finish as the original AR-15, XM16E1,  M16 and M16A1 models.

If you are looking for a Military quality Pencil profile 20" barrel for your Retro build.. or want a Light Weight Barrel for your modern build then this is one of the nicest barrels available. Fully Chrome Lined and choice of twist rate.

Barrel with Front sight base only Specifications:

  • Twist Rate Choice: 1:7 .. 1:12 .. 1:14
  • 1:7 Twist
  • 1:12 twist,  (original twist for M16/M16A1.. 1962-1982)
  • 1:14 twist,  (For Colt 601 & earlier Prototype builds. Closest thing currently made to the original Prototype/601 Barrel)
  • Front sight base with short pins (so you can remove the pins and install the rest).

Full Assembly Specifications:

  • Twist Rate Choice: 1:7 .. 1:12 .. 1:14
  • .625 at the FSB/Gas Block location
  • A1 Round Front Sight Post and assembly
  • Barrel Nut
  • 1 lbs. 11 oz.

 

Notes on Options:

Twist rate mostly affects what types of bullets you can use and your level of Purism:

  • 1:14 is what ArmaLite started with in the late 50's and were used for the first 601's. Replaced by 1:12 in about 1962.
  • 1:12 what was issued in all AR15 variants from 1962-1984 (Marines) and 1987 by the US Army. Use only 55gr and some 62gr bullets.

 

 

 * Note on Full Assembly:

 Everything is assembled and tightened to spec. Simply screw the barrel nut to your receiver, install your Gas Tube and you are Good-To-Go.

    Excellent barrel, they can be difficult to get up with but then again they are not Amazon. Once I spoke to Victor on the phone I understood how the company works and all was fine. Got the barrel and I could not be more pleased. Thank You!
