Re: SASS question
If he wants to shorten the LOP, there are several options:
1) find an A1 buttstock, pull the A2 off, remove the A2 spacer, install the A1 (should get him a reduction of 5/8");
2) get the Magpul PRS for the AR-10/SR-25 (same reduction above. with adjustability);
3) Move to a carbine stock setup.
