The upper is nice. The side charge is awesome. Took a little TLC and a bit of oil to get it to function properly at first, but after a few rounds all is well. The rest of the parts are average. The trigger has a lot of creep, but does have a crisp break and a positive break. The buttstock is just cheap. I paired this upper with a lower from Thunder Tactical and the match is just about perfect. I found some 33 round knock off Glock magazines somewhere online. I only had one mis-feed in 400 rounds of the cheapest ammo I could find. The mis-feed was was the second round of the first magazine of the test. All went smoothly afterward.
