Hi, just wanted to stop by and introduce myself as a new member. Great forum you have here. I recently bought a GSR 5.56 and I am thrilled with the quality. Did 1 3/8 group at 1oo yds with iron sights, three shot group that is. Could anyone tell me if the GSR trigger is adjustable? And does anyone know of any steel plate/ scout rifle/ woods walk shooting going on anywhere near the Lehigh Valley? Thanks and I'll shut up now.
