H&K UMP (.40 S&W/.45 ACP/9mm) Safe/Semi Lower - 2 Position

I bought one of these made by HKparts because the OEM HK lowers are always out of stock. I got it back from Tommy Built all put together, and you honestly can't tell the difference between this in-house made one and an HK original lower. Great quality, decent price, fast shipping; can't lose.

Easy to install with the B block.

Amazing lower, nice quality, and well built! Fast shipping.

Unknown to me when I purchased this, it is fully capable of being dropped on a Gideon UMP upper WITHOUT any modification. Saves a lot of nerve wrecking drilling time and arguably just as cool being that of its origin and model.

Well made lower, great snug fit with my gideon shadow upper....dont forget to get your lower push pin for the back though.

is OMEGA GIDEON SHADOW UMP RECEIVER "UMP" a drop in for this UMP and the similar german made lower semi receiver? Imconfused about UMP to USC and vice versa ( as per the last review by IRA on November 26, 2020 where he/she refers to this lower as USC for UMP mags)and would like parts that just meld together w/out any gunsmithing required.

The product description does not describe this amazing product. It?s a a complete USC lower that takes UMP magazines. The front hooks fit the USC upper, the USC trigger parts are already installed. To convert a USC to UMP you need: This lower, a stock block, stock and mill (or dremel) the upper to accept the wider UMP magazines. This lower saved me hundreds in gunsmithing!

The quality was great. I will definitely be buying another!
