Selling a lightly used Impact 737R Right hand, 75 degree, 308 bolt, AI cut. Action itself has 273 rounds fired, the 75 degree bolt is brand new. .060" firing pin.
Honestly, I like the extra clearance you get from the optic, but I think the bolt lift is a little heavier than I prefer when compared to the 90. But that is just my opinion from cycling a few times from the bench, I don't know what it feels like in actual use so it's hard to say and I don't have a way to accurately measure the difference.
