unforgiven Posted March 30, 2022 Report Posted March 30, 2022 I have an Aero pistol lower and SB4 muzzle device is 5" from gas block (mid gas) 3" from edge of 12" handguard. I could take 3 1/2" take muzzle device to edge of handguard. Lower has Aero recoil system. How do I improve the recoil system?
shooterrex Posted March 30, 2022 Report Posted March 30, 2022 What caliber? If it is not a large frame a carbine spring and buffer in the sb4 tube should work. A 12 1/2" barrel should put the muzzle device at the end of the rail.

sketch Posted March 31, 2022 Report Posted March 31, 2022 Adjustable gas suppressed. Start wtfo.. I drilled my port to .093 from .063.
98Z5V Posted March 31, 2022 Report Posted March 31, 2022 (edited) Rene, here's my 13.5" barrel in a 12" handguard. Armalite AR-10 Carbine gas - which is Midlength-ish. Plus 3/16". Edited March 31, 2022 by 98Z5V

shooterrex Posted March 31, 2022 Report Posted March 31, 2022 My gas tube was like 11 1/8" custom made. Those were the sig barrels cdnn had. I used the entire Armalite carbine kit not just the spring and buffer. No I don't own any suppressors.
