Got the kit (used my existing C3 lower) and three hours later fully functional. Everything went together smoothly and also performed flawlessly.
Very nice product..
I am a first time AR builder so I opted to buy this single kit for my lower rather than seperate upper and lower kits and I couldn't be happier with the purchase. Yes, I live in a state where I'm only allowed the 10 round magazine but that is the only drawback and it's my own fault for moving here. The kit went together beautifully with no troubles. (My only advice would be to use proper roll pin punches where needed!) The rifle functioned perfectly the first time out. It feeds all types of ammo without issues, including the steel cased stuff I got on sale. It is also quite accurate. With a cheap scope I was grouping 1-1/2 to 2 inches at 100 yards.
All in all, it is a great kit from a solid company at an unbeatable price. You can't go wrong with it.
