"Always good to have an extra"

Comments and Suggestions: Raddlock makes the only mag release that is legal in California for the H&K USC. They are hard to find. HKPARTS usually stocks or can quickly get these hard to find parts for H&K product.

Comments and Suggestions: Fast delivery and simple kit for the USC 45 carbine to make it California compliant. This is the place to go for HK parts. Great service.

Comments and Suggestions: I cant even see it, a lil bit of a hassel to insert the tool to engage the release, but hey thats what its designed go be there for. rather have this unobtrusive lock than an ugly hunk like on my sig556r.
