Suppressing M1As - thread adapters
Does anyone have experience with M1A thread adapters? I've read reviews on the SEI and Delta P adapters, but the Delta P's appear substantially more expensive. Has anyone had issues with SEI's M1A and SOCOM adapters, such as baffle strikes?

Tag, I don;t have an answer for you. I simply want to learn.

I always thought one did not want to suppress an M1A or a M1 garand. That the back pressure could lead to parts breakage. If that is the case I would look towards OSS.

As for thread adapters, I think most 02/07 should be able to propperly thread your barrel for you.

While not ideal for suppression (the action and gas system are noisy, as with many semiautos), that system can work with a can. I’ll be getting one for my M14 build, likely an SEI Windtalker to fit my Vortex flash hider. One of the main issues with putting a can on this platform is blowback. Using a Schuster adjustable gas plug can mitigate that issue.

I have a SEI adapter on my socom 16 and had a baffle strike on an AAC can. I'm afraid to use it anymore and havent considered getting it repaired .

I was advised by the guy running Hook's old shop not to suppress my M1A. He told me the Op rod is designed for the extra stress that will be put on it. He said it could be done; but didn't recommend it. I have to listen to someone that has the level of knowledge and skill he has. Suppress your AR10 and just get an adjustable gas block to cure the over gassing.
