Just need a different gas block installed on my AR-15 and have a cycling issue diagnosed.

Steve at Alaska Custom Firearms on Old Seward x Dimond does good work.

pm sent. not sure if it's ok to post the guy's name and number here.

What is the cycling issue? If you have an Armorers wrench and a couple of pin punches nothing about a gas block swap is diffucult.........I'll help ya with tech support any way I can.....

Well I think my gas tube is misaligned. Keeping hearing a loud boom when I shoot. What originally happened was I had a FF rail installed by another guy and had a railed gas block installed and after a while the set screws walked out I loctited them down ( and the flip sight seems very flimsy and i dont really trust it so i want to go back to my A2 base and i decided to get rid of my scope and bought an aimpoint) and it is sturdy now but I think when I misaligned the tube and accidentally screwed everything up. I've tried several things installing a stronger buffer spring and checking how tight my castle nut was but nothing will work and I'm stumped so I figured at this point I'd just take it to someone who knows WTF they're doing. And no I haven't been able to buy a proper punch set or armorers tool.

I found that a suppressor helps with the large boom!

Lol 223 never seemed all that loud to me when wearing ear covers it seems louder than it used to.

The gas port hole in the gas block should be a lot bigger then the hole in your barrel. It doesn't need to be perfectly aligned. For it to be misaligned enough to not put gas into the tube it would be very off center.
