Incredible deal & exactly what I wanted
I have over 50 guns at the moment including many in in the 10,000+ range. However, I have only a few AR builds 2 from Larue and 1 custom. PSA sells their products at prices that are literally lower than anyone else. So I figured why not buy an upper and lower that I could use for teaching and worst case as an extra shovel. However, after getting they very well packaged upper, blank box to cover logo and second foam lined box, I was rather surprised at how good the quality seemed to be. So I figured I would fully disassemble the upper as I always clean new ARs maticously and at the same time take a deeper look for how they put it together for 369 dollars. I didn't find a single scratch or issue and I even used a tool designed for bench rest rigs to examine the rifling and it was so prefect that I started questioning how other companies could charge 3 time more for uppers that were lower quality than this one. I attached it to a PSA MOE lower with the EPT 2 stage trigger ( trigger is so good that I left it in even though I had a Timmy on hand expecting to replace it. First time shooting I ended up putting 600 rounds of commercial ammo 62gr federal through it and my average 5 shot group, bipod on bench supported with 4.5×24 scope (costing 3 times more than the entire build together) and ended up with average group is 1.125 MOA. My largest was 3.2 moa and smallest was .42 moa (100 yards). I then ran 200 rounds of 69gr reloaded and ended up with 100 yard average being .78 MOA. I also put some 50gr z-max reloads but with the barrel twist or 1 in 7 it wasn't great. Maybe I just got lucky but for a new rifle being broke in it was shocking great. Few final points is this rifle is extremely light, like under 6lbs without scope. I know everyone focuses on M-Lol but personally I find keymod to be more reliable and I appreciate being able to essentially buy a completed upper with everything exactly what I want it to be (keymod included). The stainless steel barrel is great, I'm in the Pacific NW so the corrosion resistance is nice. However for the rest of the gun make sure to keep it well lubed and oiled with CLP. Also I reccomened replacing the flash hinder as it's by no means great. Final tip be sure you want the BUIS because this model often comes with nickel boron BCG without the BUIS and with an 18 inch barrel it's more suited to scope or an ACOG.

Beautiful upper with excellent fit and finish!
Bought this under the daily deals for $319.00 (free shipping) and very happy with it. Love the look of the stainless barrel with the Keymod rail. Gave it a 4 for quality because of the standard BCG but did not expect it to be high quality. Haven't been able to shoot it yet (to much snow in the mountains) but will check back in after I do! It pays to wait with daily checks on the daily deals to get a good buy!
