Strike Industries Advanced Receiver Extension


Are you frustrated with the length of pull for your AR-15’s fixed stock? Perhaps you feel that your ideal position is situated directly between two settings on your standard carbine buffer tube. If you feel this way, this 7-position AR-15 buffer tube is for you. Since it’s designed by Strike Industries, you can rest assured that it is of the highest quality.

An AR-15 buffer tube houses the recoil spring and the buffer itself. These components work together to cycle the action of your AR. Without them, your direct impingement AR would not be a semi-automatic weapon.

This new Advanced AR-15 Receiver Extension by Strike is a 7-position buffer tube. The shortest position the buffer tube can achieve will make it as short as a collapsed M4 carbine butt stock. If you choose to use it fully extended, the tube will extend the stock to a length slightly greater than that of an M-16A2 fixed buttstock. You can now achieve the ideal length of pull for your build with this 7-position buffer tube.

If you need a high-quality buffer tube to provide a more tailored experience with your black rifle, consider this 7-position buffer tube by Strike.

It’s a Mil-Spec Buffer Tube. How Is It Advanced?

The Strike Industries 7-Position Advanced Receiver Extension isn’t just another extruded Mil-Spec AR-15 Buffer Tube. Strike’s designers took the basic buffer tube and threw it over their shoulders before creating this beauty.

Advanced Materials:

They started with aircraft grade 7075-T6 aluminum. This higher-grade aluminum retains the lightweight characteristics of other aluminum AR-15 buffer tubes but has a lot more backbone than the 6061 you’ll see used by many other manufacturers. Finished Extensions are hard anodized. That give them a finish that resists the effects of abuse and corrosion, protecting your investment in harsh field conditions as well as from the occasional slip of a screwdriver on the bench.

Advanced Design:

The surfaces of this extension are scalloped, and while it looks awesome, it has a purpose beyond aesthetics. The scalloped surfaces reduce the friction and binding experienced when adjusting close fitting stocks and allow for weight savings while keeping the body of the tube strong. The reduced friction scalloped surfaces make it easy to move your buttstock and simple to keep track of which of the 7 positions you’re in and where you want to move to.
