Disappointed Review by
First parts were lost, then promised shims were not shipped. Weak Rainier, just weak...

However, you did remedy the situation and did quality work.

Problems with my gas blockReview by
Had a problem with this service. The pinning seemed to be done correctly. Bought a barrel with the gas block pinned. I tried removing the gas block because I still needed to assemble the barrel and the upper receiver. The gas block was on there so tight that I had to get a torch and a hammer to hammer it off the barrel. Gas block is not usable anymore due to the process: the hole where the gas tube goes in was dented. To test, i tried slipping on a same gas block, same BCM brand one on the barrel. No problem doing so. However, tried slipping the original gas block back on. would not slip back on. WAY TOO TIGHT. Gas block may be out of spec. Contacted Customer Service. (Posted on 9/16/2015)
High qualityReview by
Another high quality job done by the professionals at Rainier. You can't beat this job for $29. Clean, flawless pin installation. They even installed the set screws and applied loctite, a redundant failsafe along with the pin which means it's rock solid. Even though I take care of my weapons, I like to have the peace of mind my weapons can take a ton of abuse should the situation arise, and not fail me when I need it the most. Trust Rainier for an affordable high quality job and great customer service! (Posted on 6/4/2015)
NiceReview by
Just had them pin my new Fortis low profile gas block to my barrel and I'm very pleased with the work. I will pay the $29 to have them pin all my gas blocks in the future because I prefer the piece of mind you get when you know that gas block isn't going anywhere. Not with 2 set screws and a pin running through it. Great people to deal with too. They didn't even charge me the $15 dollars to remove my FSP for me. Which I would have happily paid because it was giving me fits. Even included a new barrel nut at no charge. (Posted on 1/30/2015)
