Well built, smooth machining and finish. Fits perfectly into the filter body. The thread matches very closely to the threaded muzzle device already on the barrel and alignment is perfect.

Very well made. It hooks up to the muzzle device I made awesome. I would recommend this to anyone who is looking for a stainless Steel end cap adapter.

I wish I had found this sooner. The end cap is well made. I would like it more if the threads were a little longer even though there is more than enough for a solid hold. Thank you
