Description
The JE Machine PS-ST8B is a skeletonized A-frame buttstock built to slip onto any mil-spec diameter buffer tube and give your AR-15 or AR-10 a cleaner, lighter feel. The open A-frame profile shaves ounces while keeping the strong backbone you want behind the gun, and the whole thing tips the scale at a trim 10.8 ounces. Six adjustment positions let you dial in a length of pull that works whether you're running a slick plate carrier or just shooting in a t-shirt at the range.
What Sets the PS-ST8B A-Frame Apart
The slim contours are the real story here. That skeletonized shape cuts down on snag points, so the stock slides past slings, gear, and clothing instead of hanging up on them. It's a nice touch for anyone who shoulders and re-shoulders a lot, and it gives the rifle a purposeful, streamlined look without going overboard. A recoil reduction buttpad comes attached, which takes some of the edge off against your shoulder during longer strings.
Sling Options on the Skeletonized A-Frame Stock
JE Machine built this one with flexibility in mind. You get ambidextrous sling attachment loops along with QD points, so you can set up a single-point, two-point, or whatever sling configuration fits how you carry and shoot. Lefty or righty, the mounting works the same on both sides.
Fit and Build Quality of the PS-ST8B
The stock is molded from impact-resistant, high-strength polymer and finished in black, and it's made in the USA. It carries true mil-spec fitment, so it drops onto a standard mil-spec buffer tube. Keep in mind the buffer tube itself is sold separately, so if you're starting from a bare lower you'll want to pair this with a mil-spec receiver extension kit. For anyone refreshing an older carbine or finishing a fresh build, it's a straightforward, no-drama way to lighten things up and add better sling versatility.

Frequently Asked Questions
Does the PS-ST8B A-frame stock come with a buffer tube?
No, the PS-ST8B is just the buttstock itself. It's designed to slide onto a standard mil-spec diameter buffer tube, which you'll need to supply separately. If you're building from a bare lower, grab a mil-spec receiver extension kit to go with it.
Will this skeletonized A-frame stock fit my AR-15?
If your rifle runs a mil-spec diameter buffer tube, this stock will fit right up. It's built to true mil-spec fitment and works on AR-15 and AR-10 platforms. It will not fit commercial-spec tubes, so double-check which tube you have before ordering.
What sling setups work with the PS-ST8B?
The stock has ambidextrous sling attachment loops along with QD points, so you've got plenty of options. You can run a single-point, two-point, or whatever configuration suits your carry style. The mounting points are the same on both sides, so it works for lefties and righties.
How much does the PS-ST8B weigh?
It comes in at 10.8 ounces, which is on the lighter side thanks to the skeletonized A-frame design. That open shape trims weight while keeping a strong backbone behind the gun. It's a solid pick if you're trying to shave ounces off a build.
