We have joined Lee Sporting and War Hammer Armaments to offer these premium and complete MP5 lower assemblies that include the following:
- Lee Sporting Lower of your choice. You can see their itemized variants HERE.
IF YOU HAVE HEARD THAT LEE SPORTING DOES NOT RECOMMEND THE USE OF SUPER SAFETIES IN THEIR LOWERS, THAT INFORMATION IS WRONG AND PERPETUATED BY THEIR COMPETITORS.
Austin Lee of Lee Sporting Lowers talks about Super Safety compatibility HERE.
- War Hammer Armaments Super Safety, Polished and Black Oxided Steel Slip Trip and CNC machined/hand polished hammer.
TO BE VERY CLEAR, THE SLIP TRIP IS INCLUDED IN THIS KIT, YOU DO NOT NEED TO BUY ONE SEPARATELY.
NOTE: War Hammer Armaments does not warranty its slip trip when used in the MAC5 series of weapons. They highly recommend avoiding them, as they are consistently out of spec by as much as 300% of the maximum tolerance the MP5 calls for in its manufacturing data/tolerances and points of weldment. If you do use one, we highly recommend grinding out the denial block along the slip trip pathway to avoid mechanical interference.
THE INCLUDED TRIGGER CAN BE SEEN HERE.
In full size models, a rubber buffer tube is not required because of the hammer profile we’re using.
We assemble these and ship them to you ready to go. The Lee Sporting shelf lowers include two sized of front shims to ensure a proper fit to your weapon. The larger one can be filed down for a custom fit.
Pistol grip type will vary based upon availability. An A2 grip is standard.
Includes a CNC machined MILSPEC trigger and CNC machined/hand polished hammer.

I love this thing. It is amazing. Works flawlessly. Customer service is fantastic. This is definitely worth it. I got the two pin setup for my Century Arms AP5P.
Jim Gann –
Ordered the complete lower for my HK SP5 and was very impressed with the customer service and product. Even though the order took a little time to fill due to the high demand, Mr. Warren was extremely responsive to my inquiries and took the time to call me and answer all of my questions. I have had absolutely no problems with the lower and it works as advertised.
Franky Despino (verified owner) –
These guys are great. Communication was top notch and delivery was timely. Product was as promised. Would highly recommend.
Mark Miller (verified owner) –
The lower works too well, smooth and burning through ammo like it’s going out of style. Seriously though quality build. I had some issues when I first installed on my upper and due to my own fault on not following instructions, I was having jamming issues. I reached out and they called me back immediately with the solve. Great customer service.
Steven Bradley (verified owner) –
This has been one of if not the best investment for my mp5 guns. Works with my HK and PTR. Warren always responded with any questions I had. If you own an mp5 design and want a super safety this is the place for a complete lower. Ive used other lowers that work but by far the quality and customer service is top notch!
Blake Rosen (verified owner) –
Absolutely top-notch customer service. The order took a little longer than expected and had an issue when it arrived, but Chase called me way after his normal business hours to troubleshoot and shipped replacement parts the same night. The thing now runs like a Swiss watch, and I am super impressed.
Seth Gunn (verified owner) –
Very fun. Once i got it working. Some issues with initial order on engagement between the slip-trip and the lever it engages. Chase promptly answered all questions and spoke with me directly at lengh on the phone. He offered to adjust/replace what might be wrong with it and paid for two way shipping to test fit in his own firearm.
In the meantime he sent me some free merch which was greatly appreciated.
I receieved the lower back in just a couple days and after some careful assembly, works as advertised.
I only have 1/2 a magazine of test fire through my gun, but I think its running as described.
This level of customer service deserves recognition and I would definitely buy from him again.
Rick (verified owner) –
Awesome service and fast
Quality looks great
These guys are top notch and on the ball!!
Dennis (verified owner) –
Well worth the wait. Customer service is the most responsive I have ever encountered.
Jason Phillips (verified owner) –
Amazing quality and flawless function on my AP5-P. I waited about 11 weeks to receive mine but MAN was it worth the wait. Had one question regarding function so I emailed customer service at roughly 730 pm pacific time and Chase replied in less than an hour. I can’t believe how easy it is and the result has far surpassed my wildest dreams. If you’re on the fence, jump off, you be glad you did!
