Clipping & Pinning Service HK Lower Housings - Poly

HK Clipped & Pinned Service - For Polymer Grip Frames

At HKPARTS we offer our own HK trigger housing clip & pin services. No one does a better job with a quicker turnaround than we do. We will clip and pin any "push pin" plastic housing for $99.95 each, plus return shipping (USPS priority mail) back to you. Have us do the work on the supplied housing that you send us, or we can clip & pin any housing purchased with HK Parts.

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 
Push Pin HK Receiver and Trigger Housing

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.

Trigger Housings Further Explained:

Can the housing styles be swapped?

Short Answer: No.

Long Answer: Regular trigger housings can be altered through our “clipping and pinning service” to fit on a semi-auto shelf.

What are the differences?

Answer: Regular trigger housings attach to the receiver with a small push pin. Semi-auto trigger housings attach by inserting the semi-auto shelf into the trigger housing.
