XTS-106 AR Collapsible Stock with Adjustable Cheek Rest and Mil-Spec Buffer Tube Assembly – Black

$63.95

The XTS-106 adjustable cheek rest AR stock bundled with a complete mil-spec buffer tube assembly. Includes buffer tube, carbine buffer, carbine spring, castle nut, and end plate. Ambidextrous. Available in black. SKU: DT-XTS-106-BT.

The XTS-106 adjustable cheek rest stock paired with a complete mil-spec buffer tube assembly — the right starting point for a scoped AR build where consistent eye alignment matters. The adjustable cheek rest slides to your preferred height and locks down firmly, keeping your head on the same plane every time you shoulder the rifle. A shock-absorbing rubber buttpad reduces felt recoil, and the ambidextrous layout works for right- or left-handed shooters equally. The included buffer tube assembly is hard-anodized 6061 aluminum with carbine buffer, carbine spring, castle nut, and end plate.

Why is the XTS-106 a good choice for a scoped AR build?

When running a scope or magnified optic, your cheek weld height becomes critical — your eye needs to be at the right height relative to the optic’s eyepiece for a clear sight picture. The XTS-106’s adjustable cheek rest lets you set that height precisely and lock it down, so you get the same cheek weld every time you shoulder the rifle instead of hunting for your sight picture.

Does the buffer tube assembly in this kit require any modification to fit my lower?

No. The mil-spec buffer tube threads directly into any standard AR-15 or AR-10 lower receiver that accepts a mil-spec carbine receiver extension. The end plate and castle nut install in the standard way. No modifications are required.

Is the XTS-106 cheek rest adjustable on both sides?

The cheek rest adjustment knob is on one side of the stock. The cheek rest itself is centered, so it provides support from both sides, but the height adjustment is controlled from a single knob rather than both sides simultaneously.

What is the advantage of the ambidextrous design on the XTS-106?

The XTS-106’s symmetrical layout means left-handed shooters can use it without modification. The sling mounting slots are accessible from both sides, and the cheek rest works equally well regardless of which shoulder you shoot from.

Can I upgrade to a QD end plate instead of the standard one included?

Yes. The standard end plate in this kit can be swapped out for a QD sling end plate at any time. Remove the castle nut, replace the end plate, and reinstall. The buffer tube, buffer, and spring remain in place.
