I've got my problematic AR15 that has just never run quite right and I'm looking to get a gunsmith to at a minimum install a JP Enterprise adjustable gas block which I just haven't had the time/tools to do myself. And if possible get the adjustable gas block dialed in with some of my ammo.
I live just a few blocks from Gunners Den in Arvada and a quick search here didn't turn anything up, so has anyone used them?

Or got any recommendations for a gunsmith in the north-west metro area?

I'm also looking to have the gunsmith get at least a rough zero on the C-More CTACT I bought for this particular AR15.
