Strike Industries New 7 Position AR Receiver Extension

    Strike Industries has always pushed the envelope on the innovation.  This time they are releasing a new 7 position buffer tube for a more fine tuned LOP adjustment.  As someone who shoots both with and without body armor, I often find myself adjusting my LOP to account for my armor.  But my stock collapsed for my armor always feels a little short.

    The new buffer tube is also longer on the last notch then a standard M16A2 stock for people with a really long LOP.  Although being a big guy myself, I never find myself at full extension and prefer a shorter LOP.

    I have always been a fan of SI and what they make.  They really are a company that blows the lid off of innovating for different platforms.  Check out their press release and info sheet below for more info.

    Strike Industries is proud to introduce our improved 7-position (That’s right not 6 position but 7) Aluminum receiver extension MIL-SPEC diameter buffer tube.  It will allow users to have finer control of their length of pull. If you have ever felt that your length of pull was in between two settings on a standard buffer tube, this is for you! The tube’s shortest length of pull position is as compact as a fully collapsed M4 carbine butt stock while its longest 7th position stretches the stock to be slightly longer than that of an M16A2 fixed stock. Our end plate is jam packed with loads of features. The first one being a quick detach (QD) build  into it for true ambidextrous shooting. It also incorporates easy attachment points on both sides for slings so you can use just about any sling on the market. This kit also comes with a receiver nut for collapsible receiver extension, also referred to as a Castle Nut. This mil-spec part with fit both the mil-spec and commercial receiver extensions
