Meet the UTG Pro RBUS3BM Mil-Spec OPS Ready S3 Stock Kit. A lean, mean, fighting machine tailored for your AR-15 or M16. It’s designed with military-grade precision to tackle heavy-duty operations. And it comes in a no-nonsense black finish.

Precision takes center stage in this kit. Crafted for tight tolerance controls, it ensures a firm, secure fit and function. No wiggle room. No loose ends. Just a snug, secure fit for your peace of mind.

The Mil-spec stock isn’t messing around. It’s molded from high-impact resistant polymer that’s ready to face the storm. Add to that, the extension tube, expertly machined from aircraft-grade aluminum. Rolled threads? Check. Anodized for corrosion and wear resistance? Double check.

Want more stability in your shooting? The rubberized butt pad has you covered. The slanted cheek rest? That’s a bonus. With these, you’ve got a firm grip and consistent firearm control.

It also boasts an integral ambidextrous sling loop and QD. Its unique 6.05″ length and sub-compact profile offers lightweight performance like no other. Six-position adjustability? You bet.

Pair it with our Super Slim Handguards for an unmatched firearm handling experience. All corners are dehorned. All contours are melted. Result? Snag-free performance and increased comfort.

And, it’s proudly made in the USA.
