"Good upgrade for longevity but as was said in another review, bit finicky to setup up and lack of proper instructions I have found makes it hard to install. Npas is a great feature but takes a bit to get just right. Would also recommend ditching the alloy screws that came with your gun, run this a bit too hot it'll snap 'em, I found that M2 X 25mm are an exact replacement size for steel ones, not a problem with them snapping since. Advice for new people to get this, if if doesn't fire properly and you hear an odd noise, do not cycle it as it could be a rail in the bolt carrier loose!

"This bolt is built to last and it's very well design. But sadly, that's how much I'm going to praise about this bolt. After installing into my bolt carrier, I fired off about 20-35 shots and my gun suddenly jammed so bad it is no longer functional. The screws that held the bolt stabilizer broke off and I can't get the remainder of the broken screw off the bolt carrier. The bolt itself was "shaved" on one side and it won't operate smoothly.What's worse I have to order a new replacements in order to save my g39. Don't get me wrong, Ra Tech is pretty nifty for an upgrade. But I believe I made the wrong choice when it comes to upgrading the bolt. I should have stick with an npas valve and a couple of plastic nozzles. Such a shame.

"Great product but is a bit finicky. You have to oil the rails of the nozzle very well top and bottom, and adjusting the npas for higher fps has to be just perfect otherwise it won't cycle the bolt properly, oil the inside of the nozzle so the npas can slide and expand the way it's designed.. I really like this product just takes some time to get set properly. I recommend starting at the lowest fps possible and turning it up one turn at a time till the gun doesn't cycle the next round. Once at that point try full auto, if it misfires any rounds lower the fps a quarter turn and fire again. Do this till it fires without skipping a bb and you'll be happy with it
