You would think being from Colt this thing would be dialed in a bit better. Spikes, slash and Rra have buffer up to 5.5ozs! Pretty heavy. Springs are available from wolf and carbin, I mean I could throw all kinds of stuff at this thing.
As long as its machined to the right size the shoulder isn't needed except to locate the spring and add preload. Otherwise flat quarters wouldn't work. Rra is a little cheaper and heavier. Maybe that and a spring and I'll run it
