Perfect fit for my retro M16 build

Comments about Double Star DoubleStar A2 Front Sight Gas Block with Bayonet Lug AR-15, LR-308 .625" Inside Diameter Steel Matte:

Installed perfectly right out of the package on my 20" green mountain M16A1 pencil barrel without any need to modify it. Don't forget to order taper pins as well since it does not come with them.

Comments about Double Star DoubleStar A2 Front Sight Gas Block with Bayonet Lug AR-15, LR-308 .625" Inside Diameter Steel Matte:

Bought this block to fit a standard contour Remington 700 270 takeoff barrel thats being converted to a 6.8. I wanted a gas block I would be able to hide under a free float tube and with a little bit of cutting I was able to make it work. If you need a very low profile gas block for a pencil barrel this one will work with a little ingenuity. Cut off the site posts and grind it smooth and you should be golden. Great gas block for the $$$

By John

from Madison, AL

Comments about Double Star DoubleStar A2 Front Sight Gas Block with Bayonet Lug AR-15, LR-308 .625" Inside Diameter Steel Matte:

I bought this sight base to mount onto the end of a Sabre Defence fluted barrel. Barrel diameter was stepped at the end, 0.728" and 0.705", so a standard 0.750" base would not fit. My gunsmith reamed the front and back bands to match the barrel diameters and installed set screws underneath to hold it in place. The sight base itself is very robust and lends itself to this type of modification.
