A pocket rocket - Maxim Defense Industries MDX 505 PDX SCW PDW Brace Upper Kit

I picked up this Maxim Industries PDX kit after watching a review from Short Shot Tony on YouTube about the now discontinued Springfield armory PDW Saint. That Saint was made with the Maxim Industries PDX kit, and after trying to find one, I decided to build one myself. The kid comes with a fully assembled upper, ready to be attached to your own lower, and it is very easy to do so. I attached it to an AT3 lower receiver with no issues. I really like the proprietary BCG and it's innovative buffer assembly. It does take some very slight finagling to get the upper and lower mated, but it's negligible. Recoil is very manageable with the 5.5" barrel, even in a 5.56 load, thanks to the HATEBRAKE. I added some MagPul Gen 3 MBUS sights (which actually took a little coercing to convince to fit on the rail) and a Holosun 510C-GR optic, and it acquires and dispatches targets like a dream. If you have the money for a Gucci Gun, this is my recommendation.
