Fit and finish,”perfect “ with a little extra. Just one thing though (instructional video) The one titled “Ambi mag release “ Should be titled Ambi bolt release !

Arrived faster the expected and looked very nice. Lines match up extremely tight and everything should fit very tightly once the whole thing is together. I would recommend.

I ordered a combo set with a slick side upper. I received it today and I was thrilled with the quality of the parts. I plan to cerakote mine, but I wanted to function-check everything before I send it off to cerakote. Everything on the lower functioned flawlessly with, and without the upper installed. My only gripe (and its kind of a big one) is that none of the 6 handguards I have will fit this upper. The front of the upper is flared out to prevent the use of any handguard that has 'alignment' tabs that would normally rest either side of the upper, just under the pic rails. I planned to build a .300 BLK pistol with this set. I had a 9.3 inch barrel and an 8.5 inch handguard already waiting for this combo set. I bought those specifically so that my suppressor would mount flush with the handguard. Now my only options are to use a different upper or buy a JL Billet 8" angled handguard and either deal with the half-inch gap and the slash-cut look, or buy a shorter barrel and hope the suppressor fits inside far enough to hide the slash-cut. Not very happy with any of these options right now and I may just try to sell this combo set to buy one that will work with the other parts I already bought. Never thought this set wouldn't work. It's a great set. The quality is great. Receiver fit is great. Finish is great (even though I'll be cerakoting it). It just won't work with any of the handguards I have.

Fit is excellent, almost zero play and what is there can easily be taken care of with the set screw. Anodizing is very hard but a little shiny for my taste (krylon will take care of that). Machines excellent and doesn't gum up like cheaper 6061 receivers. Barrel to upper fit was great, not a press fit but had to tap the barrel in with a dead blow hammer. One thing to note it the flare on the upper where it meets the handguard, of your handguard has little wings on it that overlap the upper you'll have to mill those off, but the MidWest Industries rail lines up near perfect with the flair on the upper, I'll be trying a Geisselle rail next week on my second set. I just wish I could buy the skeletor set as an 80%!
