Seats on different shotguns may vary, so before buying, check the appearance of your regular handguard. Two types are possible: Type A with a wider seat and Type B with a narrower seat. Type A corresponds to B-20U V.2.0 handguard, Type B - to B-20U V.2.1 handguard.
More information about how to choose correct modification - on B-20U product page.
We also introduce one more new product: B-19RPK upper handguard that is compatible with B-20U gen two.
Those products are already available!
