Knights Armament front folding sight gas block comes with gas tube and its pinned to a Bravo Company USA Sam-R 20" 5.56 NM 8 twist barrel 410 stainless steel barrel . Both were sent to D. Wilson Manufacturing to have the barrel properly pinned to the front sight . Barrel has about 300 rounds through it. Shoots excellent with 77 grain Nosler or Sierra bullets loaded with AA2520 powder.
Had this on my USMC SAMR build but I decided to turn it into a Mk12 mod1 since I had an extra AEM5 silencer in the safe. I'll probably regret this since it took me 7 years to find the gas block used.
**Rear pin hole on the right side of the gas block was drilled by previous owner a bit off center and it is a cosmetic issue. Pins made by D Wilson fit tight and gas block does not move .
***I'm NOT splitting the gas block from the barrel, just in case you were wondering. Selling as is in the pictures.
****Not interested in Trades . And lastly NO im not selling just the front sight .
