I'm mounting my Sparrow on a Ruger 10/22 ITAC. Factory threads, so naturally they're too long. I bought a Gemtech spacer, which consumes I think .25". Even with the spacer my threads are still a solid .5". The Sparrow takes the standard .400".
For some reason my Sparrow came with a crush washer as well, which I don't understand because there's no mention of it in the paperwork and afaik crush washers and suppressors don't play well together. Can I put the crush washer, then the spacer, then the Sparrow or would the crush washer possibly cause the spacer to not be perfectly level? |
