How to info on gas block, from a Armorer.
by Richard -
Got these when it was on sale. As an army armorer I have no problem using these gas block. They are good to go. I have built more than 2 dozen ARs and I sugest dimpling your barrel so it doesn’t spin. Also for you new builders.. roll pins comes in gas tubes. Only a few gas blocks have roll pins with them. These gas block has the sets of screws underneath, causing the gas block holes to solidly flush with the hole on your barrel. Remove the screw right under that hole on the has block. 1/8” bit, drill the gas tube hole just enough for a dent. This allows for helping allign that hole with your barrel. Easy peezy!
Love this gas block

I've used this gas block on 6 builds and have never had a problem with fit or gas escaping. I noticed some comments about "no roll pin" but the roll pin should come with the tube. Thanks, primary arms for having what I need at great prices.
Concerned about fit
by David -
Looks great but will spin easily on barrel. Even after tightening, I’m concerned about gas escaping.

Well, I just got this in. I do have concerns. First, let me say that I have had a good experience with Radical products. This block is finsed well and, while not the lowest price out there, would seem to be a good value. I do like that it is melonite, rather than the phosphate finish on most others. My concern is that it seems to be too loose when it slides into place at the journal. It can easily spin on the barrel. Even when the set screws are tight, I’m afraid it will lose too much gas around the block.
Fit Well, No Roll Pin
by Tights -
Fit seemed fine. Didn't end up using this block on my build, threw it in a draw for later use or a spare. I too was disappointed that it did not come with a roll pin for the gas tube. As a first time buyer/builder I was kind of expecting it to come with one. Without a roll pin, and not getting some or one with the order this gas block becomes expensive if you need to reorder roll pins and pay shipping on a $0.50 item. Luckily I needed to purchase some other items later and added on a few gas block roll pins so I have them and didn't need to spend extra on solely shipping roll pins.
Gas block came without gas tube roll pin
Nice finish, works great, good price. Super fast shipping as always. Thank you Primary Arms!
