Description
The Thril CCS, short for Combat Competition Stock, is one of those upgrades that instantly makes a plain carbine feel like it was built with intent. It's a compact, lightweight collapsible buttstock that drops onto any standard Mil-Spec buffer tube, so if you've been running a bland factory stock or an old A-frame, this is a simple swap that pays off the moment you shoulder the rifle. The sleek profile keeps things trim without stripping away the features that matter when you're moving fast.
What Sets the CCS Stock Apart
Where this one earns its keep is the sling setup. You get dual ambidextrous, free-rotating QD sling cups on both sides plus three manual sling slots, which means you can run a two-point, single-point, or side-mount configuration without fighting your gear. The latch sits recessed and flush with the body to cut down on snagging when you're pulling the rifle out of a bag or working around a plate carrier. Small touches, but they add up when you use the rifle for real.
Cheek Weld and Comfort on the Thril CCS
The angled, rubberized buttpad is a favorite feature among folks who've run this stock. It's removable and shaped for repeatable shoulder placement, and the textured surface holds its spot on your shoulder even in wet or dusty conditions. Owners regularly point out the generous cheek weld and the solid, no-slack fit on the buffer tube, with plenty comparing it favorably to pricier name-brand stocks they've handled side by side.
Built from a tough polymer matrix and made in the USA, the CCS is designed to take a beating and keep going. It's a smart pick for a duty-style carbine, a competition build, or a general-purpose range rifle that needs to shoulder the same way every single time.

Frequently Asked Questions
Will the Thril CCS stock fit my AR-15 buffer tube?
Yes, as long as you're running a standard Mil-Spec diameter buffer tube, which is the most common type on AR-15 carbines. It will not fit commercial-spec tubes without swapping the tube first. If you're not sure which one you have, a quick measurement or a look at your current stock's fit will tell you.
How many sling attachment points does the CCS stock have?
The CCS gives you a lot of options. There are dual ambidextrous QD sling cups, so you can mount a QD swivel on either side, plus three manual sling slots for running webbing or a traditional sling loop. That lets you set up a two-point, single-point, or side carry without any extra hardware.
Can the buttpad be removed from the Thril CCS?
Yes. The angled, rubberized buttpad is removable, and it's shaped and textured to grip your shoulder for consistent, repeatable placement. The rubber surface helps it stay put even in wet or dusty conditions, and many owners run it exactly as it comes.
Is the Thril CCS stock made in the USA?
It is. Thril builds the CCS in the USA from a durable polymer matrix designed to hold up to hard use. It also carries a lifetime warranty against material and workmanship defects.
