Last year during some of the "Black Friday" sales I bought a bunch of AR parts from different vendors with the intention of putting together a few uppers. A few weeks ago I finally got around to putting a upper together using some of the discount parts. It went together easily and head spaced perfectly.
I took it out this morning and shot it for the first time. I was very surprised at how accurate it was.
I mounted a Trijicon TA33-C 3x30 ACOG with a amber chevron and a BOBRO QD mount on it for this test. I'm going to leave the TA-33 on it.
I mounted the upper on a generic carbine lower which has a Larue Tactical MBT2S trigger (nice trigger)
I set up a 12" and a 6" steel plate at 100 meters. I had already bore sighted the upper on my property, so I knew it would be close to being sighted in.
It took me about 15 rounds shooting at the 12" plate to get what I thought was a pretty good zero using first some surplus M193 5.56 ammo then some ZQI SS109 / M855 "penetrator" ammo.
I then shot 10 rounds at the 6" plate using the ZQI M855 ammo. The results were pretty startling considering the barrel only cost $79.99.
Right at 2" . I was shooting prone using a sandbag on top of a ammo can. The Larue trigger helped a lot, and I really like the feel. Not to light, and very crisp.
All in all I shot about 100 rounds of various brands of ammo and didn't have a single malfunction. Ejection was very positive and the VG6 Gamma brake reduced recoil to virtually nothing.
So you can build a very accurate and reliable upper at a fraction of the cost using good parts bought on sale, and assembling them yourself.
I'm probably going to buy a few more of these barrels as spares.
Here is a list of the parts as well as their costs:
Upper receiver, stripped PSA "blem" (actually a Aero precision upper) $39.96
Barrel, Ballistic advantage 16" 5.56 Gov profile mid length gas system 1-7" "modern series" nitride finish from Primary Arms $79.99
Handguards, Midwest Industries MI-SLH 12.625" Mlok slim from Aim Surplus $127.96
Muzzle brake, VG6 "Gamma" from Primary Arms $39.99
Bolt carrier group, "Toolcraft" Carpenter 158 Nitride from PSA $69.99
Charging handle, PSA $9.99
Gas block, "KAK" from Aim Surplus $12.00
Gas tube, Anderson from Primary Arms $8.99
Forward assist assembly, from PSA $12.95
Ejection port cover, Strike Industries "Ultimate" EZ install. $16.95
Total $418.77
