Will the F-marked front sight base work with an A2 upper?
Sean D on Apr 28, 2018
BEST ANSWER: Although the F marked sight comes off a military m-16, the aftermarket PSA upper is to milspec standards. The gas block diameter should be identical and the front sight should fit on a PSA A2 upper fine.

Nice!
Just what I was looking for. Matched this upper with an Anderson lower, and the fit could not be tighter! Everything is better than I imagined at this price.

Outstanding value for the money
I bought this upper to build an M16A4 clone. After reading reviews I was a little nervous with some complaints that the barrel had a purplish color to it and had loose hand guards. Mine did not. The finish is fantastic on the entire upper and the hand guards are tight. I did give it 4 out of 5 stars under quality however because of a loose fitting dust cover and charging handle. The upper and lower (both palmetto) don't quite line up 100% perfect but they have a nice tight lockup. Overall I am extremely pleased with my purchase. Installed the knights Armament RAS rail and rear iron sight to finish up the M16A4 clone build and everything is perfect. Function tested a few rounds with no malfunctions but after owning nearly a dozen PSA builds I've never had one to this date. I continue to be a loyal customer. Keep up with the great products at a great price!

Quality upper
Put this upper on Anderson lower and needed accu wedge to eliminate play. Accuracy is good and improving as we get more rounds through it. Fit and finish look really good. Overall I'm very happy with my purchase from PSA.

Good quality upper
I have had this upper for about a year now. The barrel took right at 60 rounds to settle down to get the groups tight. After that I have only cleaned the carbon from the bore and NOT decoppered. It shoots very well. No failures of any kind. The accuracy using a Colt carry handle sighting through the 300-yard aperture is right at three minutes shooting either XM193 XM855 or 55 grain FMJ Wolf Gold. This three minutes extends to 300-yards where keeping nine inch groups are easily achieved when shot at a large enough target to see. This upper’s precision does not change with distance meaning that the bullet’s depart the barrel consistently. I have not shot it with a NM front post or NM hooded rear sight which should decrease group size.

fantastic upper
There is already so many amazing reviews of this upper but I just wanted to add how great this upper shoots. With an a2 carry handle it was holding 1 inch groups at 100yds with crap 55 ammo and was holding a 3/4 inch with freedom munitions 62 gr rounds. With a Psa a2 lower matched up it's a solid build for under $550 with a quality carry handle not one complaint.

Solid for the Price
Price of $299.00 is unbeatable with the free shipping. Very well packaged and shipped very fast at 6 days. Dinging the build on quality a bit as upper has anodized mismatch between upper receiver and barrel. The barrel bluing looks to have a purple hue to it which is poor match with A2 front sight and upper receiver. Not a big concern as planning to paint the barrel to match once A2 lower is built for it. Upper mated very well with the Anderson carbine lower and not quite as tight with the Delton lower slight gap with the Delton lower and PSA 20 inch upper. Slapped the Delton lower on (better trigger) and ran 60 rounds of Federal 55 grain through it at 100 yards. Barrel patterned very nice groups and very smooth to shoot not experiencing the slight recoil bounce of 16 inch carbines is nice and long forgotten how smooth running a 20 inch barrel is. Might have to sell the 16 inch toy guns haha! More money for A2 builds!! Looking forward to the A2 build completion as it will rekindle memories of shooting the A1's and A2's with irons used on service rifles. Well worth the purchase. Thanks Palmetto!
