poor manufacturing and quality control. Stay away!

Stay away from this product. I bought two and both were of poor quality. the Gas tube could not even enter the hole at all. I looked down the hole to see if there was an obstruction, and saw and the base there was crude built up. I cleaned, but still could not get the tube in the hole. The second one was only slightly better. It also had crud built up inside the tube. I cleaned it out, but there was either an obstruction or the hole was not deep enough. The tube did not seat far enough to align the roll pin holes. After multiple attempts I gave up. DO NOT BUY THIS PRODUCT!!!!
<br>From PA: I'm sorry that you had this experience. We started a return for you.

Check internal for debris before use

Looks good but had to spend half hour cleaning burrs and some sort of crusty stuff out of the inside, was plugged almost solid inside.

Works great


Not sure about the other reviews but I have 3 of these, all work perfectly.

Works fine if you know what your doing


I ordered two of these, prepared to do some cleaning based on other reviews. There was some crust in them, not a lot. Probably dried cosmoline or something. Then I installed the gas adjustment screw and worked it in and out a few times till it moved freely. Then did the same thing with the gas screw locking screw. It went together just fine, seems heavy duty and clamped onto the barrel well. I see no reason it wont work as intended when I finally get a chance to test and tun the AR pistol and 3 gun setup I built. Is it perfectly ready out of the box like a higher priced gas block, no. But for me, totally worth the 40 dollar cost savings over other manufacturers product.

I want to buy another


No problems with fit or finish/ or price. Would be glad to buy another or recommend to a friend.
