H&K MP5, 93/53/33, G3 (9mm & 7.62/.308 & 5.52/.223) SEF Navy Style Polymer Housing - Clipped & Pinned

In the questions, there were several people who used this in their PTR 9CT with no issues, but I thought I'd give MY experience. I bought this to put on my SBR'd PTR 9CT. It looks amazing, but mine required significant fitting to even go on. AS in, out of the shipping box, it wouldn't even start to go on. First of all, dimension-wise it is smaller than the PTR trigger housing. Internal dimensions (where the trigger pack sits) were .020"-.030" narrower, as was the outside of the housing. The trigger pack had a slip fit in my PTR, but was VERY tight in the this housing. I was still able to get in it with out modification, but it was very tight. Secondly, I had to remove a good amount material around the "ears" where the faux push pin is. Basically there is a ledge above the pin that had to be filed/dremeled flush with rest to get it to even start to go on. Even after doing that, it was still a very tight fit, but I didn't want to start removing material in the fear it would look weird. Overall, it looks fantastic, but be prepared to do some fitting.

I had my sear pack in an MP5K and want to see if the PTR MP5 clone would be a good sear host so I bought this housing after buying the wrong on 1st. This trigger housing is as advertised! Great fit and finish, no modifications needed at all worked great swapped it over really fast with no issues. Even if you don't have a sear this housing is great! I would definitely buy again if I get another host gun.
