One of the great things about today’s small arms market is the easy availability of parts kits. Today’s kits make it easy to get everything you need to assemble your custom rifle shipped in one package. Do you want to upgrade your lower receiver? Okay, just enter one part number and the box will hold a complete 308 lower parts kit when it arrives. Wait! That means everyone who orders the kit gets the same parts from the same manufacturer. How is that custom? It’s not. Aero Precision understands that. Rather than force you to buy parts you don’t want or need, they offer the Aero Precision AR-10 Lower Parts Kit without Trigger and Grip.
When you buy your AR-10 lower parts kit it will include everything you need save your fire control group and pistol grip. Each and every piece is manufactured to exact specifications and finished with a durable Mil-Spec coating for superior function and long service life. When you receive Aero’s M5 308 Lower Parts Kit you get: An Extended Mag Catch Button, a mag catch spring, and mag catch body, a buffer retainer and spring, Aero’s safety selector with spring and detent, a bolt catch, bolt catch roll pin, spring, and buffer, takedown and pivot springs and detents. Aero’s M5 .308 Takedown and Pivot pins are designed specifically to work with their own M5 lower, but will work with DPMS pattern lowers. The pins will simply stand out a little further than some other pin options.
Aero Precision offers their 308 lower parts kit without Trigger and Grips so that you can feel free to build a truly custom AR-10 without buyer’s remorse and guilt about unused parts collecting dust. Simply select this kit and add your own trigger and pistol grip choices to complete a fully functional, custom AR-10 lower receiver.

I've used two of these for builds. All the parts fit great. I used on kit for a Matrix Arms AR-308, and the only thing that didn't work perfect was the bolt catch pin. It sticks out a little.

Pivot pin was WAAAY to tight. Even after using gun grease i had to tap it in with a small hammer. It's loosening up with use but feels like it's gonna take while. Other than that everything worked fine.
Everything worked as it should

Magazine Catch Body

After a few turns, Aero Precision's Magazine Catch Button got stuck while screwing it onto the Magazine Catch Body. The threads were not machined well. Now that it's stuck, the exterior part of the Magazine Catch Body broke it's weld to the interior part that inserts into the receiver and through the Catch Spring. It was a lot of work to hold the interior part in place with pliers in order to screw it out of the Catch Button.
I had to buy another Magazine Catch Body locally and made by a different manufacture.
Best to get the best...

Building out a 6.5 Creedmoor using an Aero Precision M5E1 lower and this was the kit to get since I already have a Rise Armament trigger. Excellent fitment and build quality. Wing Tactical sent this fast and we'll packed. Will definitely order from these guys again!
