I was lucky enough to get two of the first sets to be shipped out. These are things are flawless. The pictures online don’t do them justice. These are my first billet lowers. I have done research until I was blue in the face, looking for a good design with great features without breaking the bank, these are by far the best value on the market. One of the big items I looked at was customer service. I promise you, the guys at F4 are beyond the best. Fast, fast replies and dealt with me being the first pain in the ass customed. They have knocked it put of the park!

excellent quality, tight fit. Ambi functions work flawlessly. paired with BA hanson 10.3 barrel and Geissele mk4 rail. best looking ar ive built and lots of positive comments on receiver set. i will note however, that the geissele rail and a midwest industries quad rail would NOT fit the upper due to contour of reciever. Milling or filing of certain rails may be required due to anti rotation tabs built in to rails. it took me ten minutes and a dremel to correct and now fits perfectly. other than that great product and will be purchasing again.
