Strike Industries Mod-1 Collapsible Stock Mil-Spec AR-15/LR-308 Carbine Polymer with QD Sling Mount

The Strike Industries Mod-1 Collapsible Stock is a lightweight, mil-spec replacement buttstock built for AR-15 and LR-308 platforms that demand practical performance without the premium price tag. If you're running a carbine that needs a more compact profile, better ergonomics, or dual quick-detach sling mounting options, this polymer stock delivers the kind of functional upgrades that appeal to serious shooters and field users alike. It's a straightforward slide-on replacement for your factory stock—no special tools or gunsmithing required.

What makes the Mod-1 stand out is the thoughtful integration of features usually found on higher-end builds. The QD cup mounting points are positioned on both sides of the stock for flexible sling setup, whether you're running a two-point tactical rig or prefer one-side carry. The enhanced cheek weld geometry gives you a solid purchase without adding bulk, and the whole package tips the scale at just 6.6 ounces, so you're not dragging extra weight forward on the barrel. The stock works equally well with or without a rubber buttpad, giving you options to tune comfort and grip to your preference (pad sold separately).

Designed to work with mil-spec receiver extension tubes, the Mod-1 fits standard AR variants without modification. Collapse it down for storage, vehicles, or tight spaces; extend it to your preferred length of pull anywhere between 9.25 and 12 inches. It's the kind of no-nonsense upgrade that gets bolted on and forgotten about—until you appreciate the ergonomics in the field or at the range.

Frequently Asked Questions

Will this stock fit my AR-15 or LR-308?

Yes, if your rifle uses a mil-spec sized receiver extension tube. The Mod-1 is designed as a direct replacement for factory collapsible stocks on standard AR-15 and LR-308 platforms. If you have a non-standard or proprietary receiver extension, check your rifle's manual or contact us.

Do I need a gunsmith to install it?

No. The Mod-1 is a slide-on replacement that requires no special tools or expertise. Simply slide it onto your existing receiver extension tube and you're done.

Can I adjust the length of pull?

Absolutely. The stock collapses and extends to accommodate a length of pull between 9.25 and 12 inches, so you can dial in comfort for your body size or to fit over heavy clothing or body armor.

Does it come with a rubber buttpad?

No, the buttpad is sold separately. The stock is designed to function well with or without one, so you can add a pad later if you prefer extra cushioning or grip.
