Anyone else having problems taking apart their PSA upper?
First i mushroomed out one punch, then bent another knocking out the taper pins on the gas block. After i finally removed the gas block I found that the folks at Palmetto state armory have torqued the barrel nut to Herculese's specs. To clarify what Imean, it has been torqued to a setting past 90 ft/lbs & I cannot remove it without damaging my upper or tearing my vice off my workbench. PSA is not returning my calls or e-mails so far (4 days), if anyonehas any tips for removing the barrel nut I am all ears.
Before you ask, yes I have a clamshell style upper action block, vice, & workbench. This is not my first upper, just my first 'problem' upper.
Any advice or help would be wonderful.
