My new Quentin Defense billet lower

Here is my new Quentin Defense billet lowers. I do not work for them and am only a customer who paid for this lower. You can look up the technical info on the lower through Quentin Defense as they would know much more than I would about them. They are extremely helpful and I am quite pleased with the service I have received from them. I do all of my firearm transfers through them as they are a local company, which is where I found out about these lowers. They also run Quentin Laser which does NFA engraving (which is where I originally started doing business with them) as well as decorative laser engraving. They are currently on sale from $169 to $155.

Quentin Defense


First off, let me state that I am extremely pleased with the quality of this lower. I put the lower together with spare parts I had sitting around. So the furniture and lower parts are mismatched, but still didn‘t create any problems. I will eventually upgrade everything and putting nicer stuff on it. In fact, I have some Magpul furniture on order as well as a match trigger. The lower went together very easily and there were no problems. Nothing needed to be fitted and everything dropped in just as it is supposed to. One very nice detail is that there are no roll pins to put the lower together. The trigger guard in part of the lower and the bolt hold open catch has a threaded allen head bolt that is used instead of the usual roll pin. On standard lowers, I have always managed to ding up the receiver when installing the bolt catch roll pin. I was always a tad nervous when pounding in the pin into the trigger guard area, afraid that I would bust off an ear. So needless to say, I am very happy with the change they made.

The lower fits extremely well with my Vltor billet upper. It also fits up with my standard A3 upper that I got from Bravo. The fit is so good that I am having a hard time deciding which upper will be dedicated to this lower. There is close to zero wiggle with the Vltor upper. While I realize it doesn’t affect accuracy, it is still something I really like and am very happy with.

Ok, I’ll admit it looks cool. I like it actually. But what advantage does it offers over a spikes tactical lower, or what ever that price comparable?

Over all, it doesn’t offer much of an advantage over a regular forged lower by the usual players (Bushmaster, RRA, Mega, etc.). I do think it adds a nice detail to my build, kind of like adding some nice grips to a pistol. I feel it is worth the extra $50-60 on a nice build to make it stand out from the crowd.

The single biggest advantage to me is the lack of roll pins. As I stated in my post, I have managed enough times to ding my reciever while installing the bolt catch. I have also seem many others as well. Not to mention I think the trigger guard is a nice detail and I don’t have to worry about busting off an ear while pushing in the trigger guard roll pin.

I absolutely love the selection of AR parts that we have now days. When I was a kid, you either had a carbine or rifle A1 or A2. A really exotic one as a 9mm or 7.62x39mm. That was the choices. Then the A3 and free floated handguards started trickling in. Now you have just about anything you want. It is a very exciting time to be into the AR scene. I don’t think it can keep this pace for the next 10 years, although I certainly hope it does. I absolutely love that I have 20 different lowers to pick from and that 5 or 6 of those are billet. These are the good old days.

Beautiful rifle, yellowcarbon! I’d never heard of Quentin Defense lowers but they look great. Since my name is Quentin I’ll have to take a look at them while I’m visiting for the Fiesta Bowl. Have a friend in Gilbert I’ve got to see anyway. Was thinking of picking up a Sun Devil billet lower but things just got more complicated. Thanks again, funny how things work out!
