Description

This is a new OEM Sig Sauer MCX Conversion Kit that includes an integrally suppressed MCX upper receiver, adapters to convert the lower receiver to accept the MCX upper receiver, and a Sig Sauer two-stage trigger. The trigger installation is required to ensure proper operation of the MCX upper receiver. Using your existing trigger is not recommended and may lead to malfunction.

The suppressor is pinned and welded meaning that the overall length is just over 16″. Putting this on your rifle will not make it an SBR.

Note: All NFA Rules apply. This item will require a Form 3 transfer to your local dealer and then a Form 4 transfer to you. Make sure you can legally own this item before purchasing.
