 With
the various rail systems currently being offered for the
AR15/M16/M4 weapon system, the Vltor Low-Profile Gas Block
is small enough to fit inside most rail systems. These gas
blocks are an excellent replacement for the archaic fixed sight
tower gas block, which has been the standard since the early
1960's.
The
Vltor Low-Profile Gas Block covers one-inch of the
barrel's surface and is made to the tightest tolerance. These
gas blocks are offered in two materials, 4140 carbon steel and
17-4PH stainless steel. The 4140 gas blocks are manganese
phosphate (black finish) to match barrels with similar finish.
The stainless steel gas blocks are blasted to give a matte gray
finish.
 All
current models are made to fit barrels that feature a .750 or
3/4-inch gas block mounting surface. In 2007, Vltor will offer a
gas block that will mount to a .625 or .5/8-inch diameter
barrel.
Installation and legal note:
The installation of the Vltor Low-Profile Gas Block should
be performed by a qualified gunsmith and/or certified armorer.
