MR1 accessories

[J0sh92]

I'm currently ordering parts for an MR1 my neighbor gave me. I'm waiting on a venturi bolt and cocking pin.
The only other thing I [i]need[i] is a new feedneck to fit my hopper. I'm looking for something that clamps on, AND eliminates the 45 degree feed if possible. I usually just point and shoot so I dont need sights.

Does anybody know of any products that might help me?
