APS SR-2 Custom Build – PRS Stock Installation
After doing a few finishing touches on my custom stock extension tube for the APS SR-2, I waited an extra day for the painted parts to dry before proceeding with the installation of the PRS adjustable stock to the rifle.

Here’s a quick peek at what the finished mod looks like.

Before we get to more images of the results, let’s go over the installation process.

To start off, here’s what the finished stock extension tube looks like after sanding it with 320, 600, 1500, and finally, 2500 grit sandpaper. And yes, it reminds me of the days when I lapped CPU heatsinks for overclocking. lol.

Chrome finish on the tube, with zero black camo paint on the exposed parts.

Custom length steel bolt, with washer, inside the extension tube.

Extension tube fitted into the APS SR-2 receiver guide.

Custom stock extension tube fitted to the APS SR-2 lower receiver;
with the threaded end cap secured into place.

PRS stock fitted onto the new assembly.

Securing the PRS with a secondary bolt that goes into the threaded end cap.

Here are a few more shots of my APS SR-2, in full view of the rifle, with the PRS stock installed. The total length is now 50 inches, and although I haven’t exactly weighed it yet, it feels like carrying a 50 cal. around. Well, almost. lol.

I’m quite happy with the outcome of the mod. Along with the internals on a previous upgrade, everything turned out great. 😀

My next mod would be fitting a PSG-1 style sniper grip to this rifle. And again, having non-standard parts, that would require machining a block of tempered aluminum to make the rifle compatible with the grip.

A more immediate concern though is sourcing out the sniper grip itself. I seem to have a knack for requiring things at a time stores are mostly out of stock. lol.
