The Rapid Attach Buttstock Adapter allows you to greatly reduce the length of your firearm for compact storage and easy transportation without any modifications. It allows for the attachment and removal of your buttstock or pistol brace in seconds.  

How to use: 

To detach, push the button and twist counter-clockwise 30 degrees.The buttstock will then be separated from the firearm. To re-attach, align the two pieces, push in and turn clockwise 30 degrees. The steel locking mechanism automatically secures the adapter. It's 7075 aluminum construction and steel internals make the RAB-AD both robust and lightweight. The RAB-AD is designed for gas piston, direct impingement, direct blow back and radial delayed blowback systems in the AR platform.

    While I have not yet installed or used this product, as a retired machinist I am impressed with the design and execution of this item. The inclusion of needed tools is a big plus. While the price point seems a bit high, the fact the manufacturer donated part of his proceeds to Gun Owners of America made it more desirable to me.

    Product and customer service

    Top Notch customer service. That's the reason for this review. I've never taken the time to do a review, but when you are refunded 20 percent before your order has even shipped, over a holiday weekend. You are doing something right, and got an email response to boot! Product is great, but the service was even better! Great Job, and thank you for the quick response and fixing the coupon code.

    Works well. Placed on a Magpul PRS stock with A2 style tube. Would prefer a larger (wider / rectangle shape) release button. A good alternative to a folding adapter.

    AWESOME!!! Very easy to install and operate. Adds about an inch to the overall length of pull on your AR. Makes a full size AR fit in a SBR case. Definitely plan on buying another in the future.

    I replaced two Rellim Arms kits on an AR15 and AR10. This seems much more polished and thought out, easier to break the rifles down, and that adaptor to torque the ring is better than any Law Tactical castle nut wrench. Plus no weird buffers or BCG attachments.
