I have a brand new take off pistol grip stock for a Tristar Viper G2 shotgun in New Bottomland, this stock will fit 20, 28 gauges and 410. 100.00 and will ship on your dime. Posted elsewhere so time stamp applies.
I have a couple Tristar Viper G2 Turkey guns with that stock on it. It's one of the most comfortable stocks I have ever used and definitely the best shotgun stock I've tried. I would buy it if I had something to put it on.
