7.5 pistol kit for ar15 - CBC Industries AR-15 Complete Upper Receiver Pistol Kit, .223/5.56, 7.5in

Okay. I love the length and the kit came with the buffer and spring and the lower parts. The upper fits well on the James Madison lower which is a carbon fiber lower. The kit had everything I wanted for this build and on the first firing of it, I was very happy. But there was a problem after about 40 rounds. The gas block came loose! I found also the handguard was also loose! It started to short stroke and I had to remove the handguard and I had to blue locktite the set screws on the gas block. That is my only complaint. The bcg was very tight but it worked in nicely. 4 stars because the gas block and the handguard were loose. I do recommend this product though and.if you buy it, check both of those before you shoot it and I would take the bcg out and take it down and lubricate it well. But if you're planning a pistol build, this kit is the way to go!
