I have a Nordic Extension kit that I used in 1 3gun match last year. I bought a new shotgun that came with an extended tube, so this one is now redundant.
Perfect for use on a home defense PBS or A5, or for someone that wants to dabble in 3gun before getting a gamer shotgun. All the parts can be moved to a different gun with the purchase of a different magazine nut.
$50 in Woodbury or business hours in Maple Grove.
Trades: #7.5 or #8 shot target ammo, low recoil slugs (both 2 3/4")
EDIT: this includes the barrel clamp.
