Meet the Breaching Stock AR
So last week I spoke with one of the inventors of an AR-15/M-16/M4 accessory that allows a rescue tool to be mounted on the end of a firearm. And I have to admit, I think it’s pretty cool, and under the right circumstances could help save lives.
“The insertion body is ideally formed in a shape that will aid emergency first-responders, law enforcement personnel and/or military personnel in entering buildings through entryways such as, for example, secured doors and windows,” reads the abstract on Patent# US20160153742.
Now I know 7075-T6 Aluminum is tough, but if you were serious about this you would need a stronger than spec (maybe milled steel?) lower and correspondingly thick steel buffer tube for this to work more than twice and not ruin your weapon, which means instead of a 6-7 pound gun, you are looking at more like a 10-15 pound gun depending on the breaching attachment, but it still has a niche purpose.
Of course, for those using it, they would want a clear/safe weapon before they turned it into an entry tool, but as anyone that has experience with an AR will testify, you can make one hot again in a second or two.
Further, a crow foot pry bar on the back of an AR pistol would be a tool, not a stock, which could have really neat and non-NFA applications similar to the SIG Brace.
