VLTOR .750" Low Profile Stainless Steel AR15 Set Screw Gas Block GB-2SS
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 tolerances. These gas blocks are in 17-4 PH Stainless Steel and available in silver stainless steel finish.
All stocked current models are made to fit barrels that feature a .750” (standard) diameter barrel. Includes GAS PIN and 2 SET SCREWS.
Product ReviewsPosted by Corder from Tennessee on 9th Apr 2011The Vltor gas block is probably the best low-profile gas block on the market. Its designed to be extremely strong yet tiny. It fit under my PRI Gen III handguard perfectly. I will buy another one for my next build. Thanks, Vltor.
Overall Width: GB-2S and GB-2SS: .925-inch
Bottom thickness (measured from the centerline of the bore) GB-2S and GB-2SS: .560-inch
