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.

  • Advanced receiver extension

    Looks great installed, works great too.

  • Awesome buffer tube

    Posted by Tim Vaughn on 17th Dec 2019

    This tube is awesome in every way. Seven adjustments in standard carbine length tube, drain holes, lightening contours, extended carrier support. Best of all, the FDE blends perfectly with my ATACS AU camo the rest of the gun is in.

  • Real Quality Receiver Extension Tube

    Posted by NATHAN CUNNINGHAM on 5th Nov 2019

    I purchased this for my M&P15 Sport2 which has turned into a AR Rebuild project. My stock buffer tube had damaged threads and the Magpul ASAP QD end plate turned somehow and the end plate key that locks in rotated over the threads damaging them and causing the tube to spin then causing the stock to not line up. Basically I purchased the black version of this Receiver Extension Tube and it was worth every penny. The anodizing is consistent and looks good. The quality of the machining is excellent with a style of their own. The fact that this is 7075 aluminum was another plus as well as it having 7 positions of adjustment instead of the standard 6. Another point of interest for me is the spring & retainer lip on the front of the tube which help to keep the buffer tube exactly straight. I have a magpul CTR stock on with this and with the Friction lock dis-engaged it rattles around alittle bit, but with the Friction lock engaged it feels a lot more solid then it did with the stock tube. Hopefully the anodizing holds up over the yrs but I highly recommend this buffer tube.

    Awesome 7 position buffer tube! Finish and all was very nice!

  • Nice Finish and Design

    Posted by Firesharksar on 15th Jul 2018

    Overall seems to be a good tube. This was a replacement for the previous model Strike Industries discontinued. They did raise the price considerably over the discontinued model but it really doesn't have that much difference in the old design. A few more bevels and tapes but otherwise not sure what they changed. It does have a nice finish and seems solid. My Magpul stock does fit very snug but I think once it gets worked a few times it will loosen up. Seems to be a little bit tighter tolerance on the "mil-spec" end for overall tube diameter. The color does match perfectly with other SI Red Line parts as well as Odin Works red parts.

  • Great quality and color finish

    Looks really good and has extra positions for your stock. Color is a metallic blood red and it is pretty amazing on a black rifle.
