Take a look at Rugged. I’ve been very impressed with their design, especially the front blast baffle being the only serialized part and the ability to convert from long to short. I have their Obsidian and Oculus inbound.
Something else to consider about suppressors is the accessories’ cost. My AAC 556 can was under $500.......but the QD muzzle devices are $75-100 each. Luckily I found a couple take offs to spread around on my other ARs. The pistol cans require either a fixed barrel mount or spacer to replace the spring........both sold separately, lol. Some of the more expensive cans have these accessories included.
Also great info about pistons and what not to do.
Yikes. That sucks.
