Nice, details on your AR?
Palmetto State "PA10" .308
Gen 2 18" Midlength Stainless 1:10
Cheap $30 no-name mount from Amazon that actually holds zero! Leupold scope on top (shout out to the Washington State Trappers Association "raffle"....everyone should attend the rendezvous!

).
A2 front post isn't an issue with the scope, but probably should have gotten one without it.
Haven't had one issue with it. Over 350 rounds so far. Mainly been practicing with some cheap Malysian surplus ammo from the 1980's.
Hunt/dialed in with Fusion 150 grain.
PSA makes some nice stuff for the price. Lifetime warranty too.
