Thread: AR-15 Suppressor - Adjustable Gas Block Required?

I went through the exercise recently and found that a heavier buffer and an adjustable gas block transformed my carbine. Before hand, it recoiled reasonably hard and there was a lot of gas coming up under my safety glasses making my eyes water. It is a lightweight carbine with 12.5" barrel and after 50 odd rounds it was becoming unpleasant to shoot with watering eyes and a yellow bruise forming from the plastic Armaworx stock. My suppressor is an ASE CQBS-BL which is a compact unit and as a consequence creates greater back pressure. I first moved to an H3 buffer which slowed things down about 10% but the best thing I changed was the gas block. A Dean Maisey adjustable gas block softened the recoil, eliminated the gas and allowed control of the brass ejection to land in a sweet little pile at 4:00 so I don't have to grovel around in the grass at the range. Don't get those horrible little cheapo gas blocks on TM as my one seized after 20-30 rounds because of the grub screw being too small. Dean's gas block has a massive adjustment screw which is indexed so you can easily alternate between different applications and will not ever seize.
