Ruck block/take down storage block for AR-15 or AR-9.

Keeps the bolt of the upper receiver in place while the rifle is taken down. A cable lock can be added to secure the rifle during transport or storage. This makes carrying in a case or back pack more secure by keeping all the parts of the rifle locked together. Holes in the center allow it to be strapped down or have things strapped to it.

Great for bug-out bags and survival kits or hanging in your safe.

3D printed polymer, pins included. Shown with AR9 Pistol which is not included.
