Prefect fit buffer tube adaptor - Grand Power Stribog Ar Brace Adaptor

I had this on one of the early-import Stribogs (i.e. one brought in by Eagle Imports with a reciprocating bolt). Like the factory end-cap, this fits very snuggly. I experienced no wobble or rattle of the adaptor whatsoever. Buffer-tube mounted braces are plentiful and varied, so this adaptor gives you a lot of options if you’re not interested in the side-folding Picatinny-mounted options or collapsing braces built directly on their own replacement end-caps. I use this a lot with an SBA3 brace and had no complaints.
