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 a nice, clean, fit too tight HK tolerances.

We finish the process by taking the time to permanently epoxy a factory German push pin in place (Push pin included in price). This effect allows us to “mimic” the look of a true push pin HK lower housing.

Price for this service is $69.95 each + return shipping (shipping is added upon checkout.)

The Quick and Dirty Explanation

What does “clipped and pinned” mean?

Answer: We are 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.
There you go, happy shopping.

Trigger Housings Further Explained

Can the housing styles be swaped?

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 the differences?
