Should you get a complete rifle, or build it one piece-at-a-time, like Johnny Cash? Let’s start with a couple of the smaller parts like the dust cover and forward assist. You know that you need them, and you shouldn’t run without them. Now you have the power to decide where to get a 308 upper parts kit and get all the parts for both at once. Aero Precision quality at a reasonable price is just a click away.

What Makes Your Ideal Gun?

The easiest thing to do is buy a complete weapon and be done with it. But, is what you really want? Well, that depends on your needs, skills, and purpose for the gun. If you’re starting and have no specifics in mind, then going with something off the rack is probably the way to go. However, if you have something in mind that just isn’t out there. I bet the notion of getting individual parts, and building what you see in your head has crossed your mind.

In This Case, Opposites Do Not Attract

Unlike the mil-spec AR-15, which enjoys parts conformity, the AR-10 can be a finicky critter. Therefore, now is not the time to mix-and-match parts. Altogether, an AR-10/M-5 is going to cost more. So, now is not the time to try something just for fun. If you’re finishing a new Aero Precision build, don’t gamble your money on anything but an Aero Precision 308 upper parts kit. Is that AR-10 that has been rambling around your mind getting ready to turn real? Getting all the components from a reputable, quality manufacturer like Aero Precision is a smart move. You will save time, and time is money.

    Functions fine but the finish was terrible. It all has a rough, parkarized finish with so many swirl lines it looks like splatter paint. It sticks out like a sore thumb on the anodized finish of an Aero M4/M5 reciever set. This kit went straight to the spare parts drawer.

  • Nick UPK!

    This Aero Upk was installed on a stripped DPMS low-profile upper. The fit and finish of the parts were outstanding. Really like the fit/function of the FA. Installed that one using a roll pin instead of the screw as not all uppers are threaded for it. The port door pin is a little long for the DPMS upper also, but easily trimmed to fit perfectly! Overall quality of the UPK is nicely done!

    Wing tactical was fast with shipping and priced right. I love aero and use them for most of my builds. Ths parts are all functional but the finish is a little sloppy looking. Purely cosmetic though
