I got to test shoot the modified '76 over NY weekend. All ion all I'm quite happy with it. A little more "push-back" when firing, but nothing terrible, and seemed to nudge evenly across the front of the shoulder, so the "pitch" will work for me. It slides right up under my arm without snagging on clothing - I like that SG butt plate. Also balances out very nicely - kinda like a Enfield Jungle Carbine - short, sweet, and potent!
Groups with T-7 under a 350 gr. bullet were about 3" at 50 yards, but I was leaning against a railing post in 20 degree weather, so they probably could have been better with a good solid rifle rest.
On a side note, I need a replacement extractor for one of the rifles, but VTI is out of stock. Anyone know where else to order one?
