Clipping & Pinning Service HK Lower Housings - Poly

HK Clipped & Pinned Service - For Polymer Grip Frames

We will clip and pin any "push pin" plastic housing for $99.95 each plus return shipping via USPS priority mail. Our technicians can perform the service on a customer supplied grip or we can clip & pin any housing purchased from our site.

Please Note: We only provide clipping and pinning on polymer housings NO metal grip frames.

Quality Finish: We use the proper machining equipment to take your push pin lower housing and mill out the area that is needed to fit a semi-auto shelf of your HK receiver. We then professionally trim and polish the edges of the milled area for nice, clean, fit-to-tight HK tolerances. We finish the process by taking the time to permanently epoxy a factory German push pin in place (pushpin included in price). This effect allows us to mimic the look of a true push pin HK lower housing.

Mailing Instructions:

Send us your plastic housings ONLY. Please, no trigger packs or selectors (they are not needed anyway) only send the polymer housing that needs to be clipped & pinned.

The Quick And Dirty Explanation: What does “clipped and pinned” mean?

Answer: We're referring to the front attachment point of the trigger housing to the receiver.
Check out the receiver examples below.

Example #1
Semi-Auto Shelf HK Receiver.

Requires clipped and pinned trigger housings or semi-auto metal trigger housing.

Example #2

If your HK receiver looks like example #1 then you have a receiver that needs a clipped and pinned trigger housing or a semi-auto metal trigger group.
