HK UMP Build service (Customizable with your kit)

Build service for the H&K UMP45, UMP40, UMP9, or UMP10 with your parts kit, you provide the kit and all the parts you want installed.

If you have an unmodified full auto bolt in your kit, DO NOT SELECT "No Bolt Machine Work". That option is ONLY if your kit already has a machined bolt to fit the semi-auto receivers. Even if you are an FFL with an 02 SOT, If you want to build into a post sample, you will STILL need bolt machine work.

This service includes fitting all the parts, installing the barrel, installing rails and accessories if added to your cart, doing a semi-auto conversion on the lowers, machining the bolt to fir the Semi-Auto receiver etc.

If you need a receiver, we have S5 Tactical receivers we can use to build your gun.

If you just want a complete UMP ready to go, check out our options here

If you add additional parts to your order, like hand-guard rails or top rails, we can install them with this service.

When checking out, please make sure to specify the FFL you want the firearm shipped to when completed. If you are sending your receiver, make sure to send it with a copy of your ID, or use your local FFL to ship it to us, and make sure they send us a copy of their FFL with the shipment.

Turn around time is ~2-3 weeks from when we receive your parts
