MP5/SP5 HK93 HK91 Removable carrier sear trip modification service

Description

I CANNOT ANSWER “Did you get my carrier?” EMAILS/MESSAGES. If this is a concern, you have to add delivery confirmation when you ship your carrier in and use that as your confirmation. I get way too many emails/messages asking if I can confirm we got their parts in. Apologizes, but it just takes to much time away from actual work. Thank you for understanding. 

This is a service done to you current bolt carrier. Can be done to full size or K size carriers, full auto or semi auto. This modification allows you to run a legal posti pack, registered sear, registered trigger pack and FRTs in your HK SP5, SP5K, HK91/93 or any HK pattern “9X” pattern semi auto carrier without modifying the receiver. This also works for the MKE, MKEK and POF receivers that have full auto carrier block plates. The benefit is being able to use your legal full auto trigger packs while keeping the host weapon a title 1, none NFA item. The host weapon retains its value and remains unmodified. You purchase the service, send your carrier in and we modify it to accept a removable sear trip. This service is for semi auto or full auto carriers. Once you receive the carrier back, you install the carrier as normal, move it forward past the carrier block plate and then install the sear trip. Trip piece is only tightened to 10-12 INCH pounds, if you want to use thread locker, we recommend the one in the product pictures, ONE drop only. Now you have a full auto carrier within your receiver. Price includes modification and machine work to your current carrier, tool steel sear trip piece, Torx screw, blue recoil buffer/spacer (full size carriers only, K size carriers do not use the blue buffer) and return USPS 1st class shipping. This modification works on: HK SP5,  MKE/Zenith full size and K, POF 9mm and HK MP5 40/10mm carriers. THIS IS A SERVICE DONE TO YOUR EXISTING CARRIER YOU SEND IN. Modification does not include a carrier refinish, however,  CeraKote refinish is an option. Price includes modification and machine work done to your carrier, tool steel sear trip piece, Torx screw and recoil buffer/SP5 spacer*. K size carriers do not come with or use the blue buffer, only the full size carriers come with and use the blue buffer.

IVE ALSO ADDED THE HK93 AND HK91 CARRIERS TO THIS SERVICE. FOR THOSE WHO WANT TO RUN POSTIE PACKS OR REGISTERED SEAR PACKS IN THEIR HK93/91 AND NEED A FULL AUTO CARRIER TRIP, BUT DO T NEED TO PURCHASE AN NEW, FULL AUTO CARRIER. 

ALL NFA RULES APPLY!
