X15/AR15 Gen 2 Lower Receiver Details

Our X15/AR15 Gen 2 Lower Receiver is very similar to what you would expect from a mil-spec AR15 Lower Receiver, with a few added features to help with assembly and use of the firearm you intend to build.

The first thing to point out is that our AR15 Gen 2 lowers have an increased magwell flare, allowing for easier insertion of magazines compared to standard mil-spec lowers.

Our AR15 Gen 2 Lower receivers include a nylon tipped tension set screw threaded into the lower receiver, located adjacent to the grip screw threads. This allows the end user to tighten it down to the desired fit, removing any slop between the upper and lower receivers when they are mated together. Although we see very nice fitment between our upper and lower receivers, this is a great feature when our lower receiver is being used with other manufacturer’s upper receivers.

At the very rear of the receiver, we thread our takedown pin detent holes to accept a 4-40 set screw. This allows the builder to install these parts independently of the buffer assembly and avoids headache and frustration when trying to keep the detent spring compressed while threading the end plate and castle nut onto the buffer tube. The 4-40 set screw is not included with the lower receiver, but it does come with most of our AR15 Lower Parts Kits.
