While we’re on the subject of tactical AR (AR-15) carbine/SBR accessories and components/parts, we should probably mention Strike Industries (SI) has just introduced their new SI 7-position Aluminum AR (AR-15) Receiver Extension/MILSPEC Buffer Tube in two formats, the SI AR Receiver Extension with 7 Positions, which is just the receiver extension/buffer tube by itself, and the SI AR Receiver Extension with 7 Positions – Assembly, which includes a feature-rich QD (Quick-Detach) end plate designed for ambidextrous shooting, with multiple sling-attachment points. A receiver nut/castle nut also comes with the slightly-more-expensive package.

The Strike Industries SI 7-Position AR Buffer Tube/Receiver Extension’s primary advantage is that it provides the shooter with finer control of his/her length of pull, stretching your telescoping/retractable stock (buttstock) to become slightly longer than an M16A2/A4 fixed stock in the 7th position, and being able to collapse the all the way down to the same compactness as a fully-collapsed M4/M4A1 Carbine stock. Pretty cool.

Nice little package at a great price, as usual for SI.

The following information on the two variants comes directly from the Strike Industries website:

AR Receiver Extension with 7 Positions
SKU#: SI AR-RE7P-BT

Availability: In stock
MSRP: $24.95 USD

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.

Package include:
» 1x 7-Position MILSPEC Buffer Tube

Features:
» 7-position MIL-SPEC diameter buffer tube
» Fits onto any standard AR15 receiver.
» Finer length of pull adjustment.
