New video: our Doorbuster 12 gauge firearm based on  Black Aces Magazine receiver

This time we wanted to build a door buster SWAT gun as much as legal you could have. The only legal way to do it was to start from a virgin Black Aces magazine receiver , add a SBA3 brace and a barrel just long enough to get to the minimum firearm overall length of 26". This implies that the gun cannot go under 26" overall length so the tube and brace CANNOT be legally removed.

We also made the Black Aces system a little more reliable and found a way to use PGM and Pro MAG SAIGA magazines on this gun (we will publish a video on this pretty soon).

The gun is very reliable and would say on a par with any Shockwave or similar. The PGM and ProMag magazines are even smoother than the original Black Aces mags. We will show how to modify them pretty soon. We also added a flashlight system and a solid front grip system. Enjoy.
