Howdy Horde. I was wondering how the forged uppers compare between PF and Aero Precision. They are about the same price wise. I am also looking for a few good compensators. I need one for my 16" group buy and one for the 18" when it arrives. The 16" is a combo hunting/SHTF piece and the 18" will be strictly a hunting rifle.

That said, buy from PF.

I built a custom AR for a friend's daughter with an Anderson lower.
The pistol grip screw threaded channel was too short for a standard grip screw, so I had to use a Magpul short grip screw. Easy fix, but something I've not seen before having built untold guns since the 1990s.NRA Basic, Pistol, Rifle, Shotgun, RSO

Both Aero and PF are great products and have never had a problem with either one of them. Aero does offer them in different colors now. Mark can also Cerakote them for you too. BANG BANG!!
The other day you just missed a new brake just for Grendels from Odin!! PF has good brakes too. AR Performance makes a good muzzle device also. BANG BANG!!

Very true. I've only used the Anderson 80% lowers and I do the machining on a Bridgeport milling machine. If there is any problem (which there isn't) I only have myself to blame. I've done four of them and haven't had any problems. As far as the grip screw Anderson only threads 3/4" into the lower. Before I assemble one of their receivers I run a 1/4 X 28 tap thru the receiver and there is no problems with it.

With many AR builds behind me, have had to re-tap the grip hole several times with no singular vendor being the sole culprit ( frequently put a set screw there to take out some of the M/S trigger creep ). This is an equal opportunity short-coming among vendors.
