Anyone know of a suppressor (preferably integral to barrel) for the AR-20?

Um....what's an AR20?

Quick google search turned up some....interesting things. Only thing close to being gun related was some kind of warship Hull.

It's on the bottom. Short answer - none designed for it.

Longer answer - you could easily get one made for it/get the barrel redone for it. :)

A take-down .22 nicely sized for backpacking.

Turn the barrel, toss some threads on it, and stick one of these on.

All of the AR-7's that I've shot had issues in reliability and function.

Personally, I find that a .22 semiautomatic target pistol is almost as accurate as a target rifle and more accurate than many .22 rifles. For backpacking, I would go with an integrally suppressed Ruger .22 pistol.

I'm waiting now for the paperwork to clear on a Gem-tech Piranha .223 suppressor. I got the screw on so that I could use it on different weapons. I've got three .223's and I'm going to check with Gem-tech to see if I can use it with .22 weapons.
