SKU: Bren/MCX Adapter Combo Kit Category: Tags: , , , , , , , ,


Our CZ Bren 805 & MCX Stock Adapter Kit will allow you to easily and quickly adapt your Bren 805 rifle or SBR to accept the Sig Sauer MCX folding stock. The stock will fold to the left but will not interfere with the function/operation of the reciprocating charging handle. The Sig Sauer MCX folding stock is supremely lightweight, streamlined, and compact without sacrificing rigidity or durability and makes an excellent fit with the Bren 805. You’ll have to see it to believe it!

Our CZ Bren 805 adapter supports a standard AR15 buffer tube with ease. Coupled with our MCX stock adapter, the overall length added to your SBR or rifle is minimal!

The MCX adapter kit is composed of two parts and an attaching bolt. The externally-threaded adapter plug fits into the threaded buffer socket or ring. The adapter rail section firs into the slot in the adapter plug and the two are secured to each other and the firearm by a hex-socket bolt and lock washer.


Included with our Bren 805 block adapter are two soft-tip screws and two standard screws that be used to eliminate any wobble or play in the adapter. They are OPTIONAL and are not required for installation. If you have any questions pertaining to this product, contact us at
