The best i've found. - Riflespeed Gas Control .750in Assembly Block

I recently installed the RifleSpeed gas control block on my suppressed AR and it’s been fantastic. Being able to fine-tune the gas has noticeably reduced recoil, eliminated gas blowback to my face, and kept the action much cleaner. Installation was easy and straight forward, the adjustment knob was easy to use and felt good, and the build quality feels top-notch. This is one of the best suppressor upgrades I’ve made. Highly recommend it to anyone running suppressed or not.
