Repair on Barrel
Can the Guide Pin to a 9” 300 BlackOut Barrel be repaired? What happened was I was swapping out a upper without Fwd Assist and Deflector to one with. After I installed it and Torqued it, I tried to insert the Group Bolt Carrier and it won’t align or insert into the Barrel Extension. After disassembly I noticed that the Guide Pin was loose.
