what would happen if i did this????

[jonny rotton]

i left it as is... i built another with a mcgowan 12" light weight barrel. i put in the lite bolt carrier and regular buffer and spring. i put about 25 rounds thru it without any malfunctions. my first group was 1.5" then the next three were all sub moa with factory sst. i then put some wolf steel cased ammo thru it. it shot 1-2". my friend with the same barrel had a 2.5" group at 200 yards. the barrels like the wolf. lol how funny is that?/
