The TacFire MAR050S is a mil-spec buffer tube assembly with a 6-position adjustable stock and buttpad, designed as a drop-in replacement or upgrade for AR-15 platform rifles. Whether you're building a new rifle, upgrading a stock setup, or just need a field-proven stock solution, this kit gives you a clean, no-nonsense option in black that won't break the bank. Mil-spec dimensions mean it'll work with standard AR receivers and components you likely already have on hand.
The 6-position design lets you dial in the length of pull to suit your body armor, gear, or just your personal shooting preference—crucial for comfort during long range sessions or hunting trips. The included buttpad provides a reasonable cheek weld and absorbs recoil energy better than bare plastic or metal. This is the kind of stuff that matters when you're behind the gun for hours, not just in the glossy product photos.
TacFire keeps things straightforward and affordable without skipping essentials. You get a mil-spec tube, the stock mechanism, and buttpad all in one kit. It's a solid choice for shooters who want to get their rifle running without paying premium prices for cosmetic frills.
Yes. The TacFire MAR050S is mil-spec, which means it's designed to work with standard mil-spec AR-15 receivers. If your rifle uses a standard receiver extension tube, this stock assembly will fit.
Each position moves the stock closer or farther from the trigger group, letting you customize your length of pull. This is especially useful if you run body armor, heavy gear, or just need to match the stock to your natural shooting position.
The kit includes the buffer tube assembly, the 6-position adjustable stock, and the buttpad. You get everything needed to install it on a compatible AR-15 receiver.
