Williams Shotgun 12 Gauge Slug Sleeve : Barrels at GunBroker.com
I wonder how this would work with a Saiga-12. Current bid only $5 so it may be worth trying it out. Is there the chance this could shoot off? The clamp looks rather snug with the three bolts.
I can't find anything about these, not sure if they would be good for a Saiga or not?
