i added a plus two to my full length tube so my m4 holds 9 shots in the tube
that gives me a 9+1+1 i have fired over 200 rounds of mixed bird,buck and slugs shoots great.
i just sighted mine in with federal truball low recoil 1oz. slugs
it shoots about 3" groups at 50 yards.thats not bad for a smoothbore
with ghost ring sights.
i installed mine last weekend it looks and works great at 68.00 shipped you cant beat it.i mod. mine to hold a nordic plus two so now i can get 9 rds in the tube.
i looked at two this weekend in michigan.one was 1389.00 the other
had a stocked that looked like a collapsible stock but it didn't collapse
it swiveled it was 1575.00
