Description

We are posting this PRE-ORDER for : 1x Gas Block & 1x Trunnion to fit the CZ Bren 2 MS barrels.
Here’s the skinny – This pre-order guarantees your place in line to receive the parts once we have them finished and ready for sale. This is a ‘virtual’ pre-order so no shipping has been applied. Once we are ready to ship you will be contacted and the Canada Post charges will then be due before the parts go out the door.

UNTIL THE PARTS ARE READY TO SHIP, if you purchase a set, you will need to be patient and NOT contact us for updates. We can only do this pre-order under those conditions as we are a small shop and need to actually work to get these done. (The trunnion in the display picture has not been Nitride finished yet. The final iteration of these will be black just like the part on your Bren 2)

We are offering these parts two ways. You can have them shipped to you to be installed by a QUALIFIED GUNSMITH in your area, or you can ship your take-off barrel to us and we can install them for an additional fee.

The parts themselves are not enough to make this a complete drop-on package unfortunately. What this pre-order is for is a stripped bolt-on gas block and a barrel trunnion. You will need to reuse the following gas system parts : the piston itself, piston head, piston spring, gas regulator, gas regulator latch and roll pin. The gas block will come with screws and the trunnion will come with oversize cross pins for installation.

Again, and we cannot stress this enough – If you choose to just have us mail you the parts then they MUST BE INSTALLED BY A QUALIFIED MACHINIST OR GUNSMITH. We will not be giving advice nor will we be liable for any home installations gone wrong.

Now for the technical DETAILS ! The trunnions  for all calibers and all barrel lengths are the same. However, the gas blocks (built WAY beefier than the thin factory CZ part!) come in two different versions, one is for 16mm barrel journals and one is for 18mm barrel journals. It is up to you to determine which you have and would like to order. We cannot change which size you get once you have reserved your set, sorry.

I can help a bit from what we have learned about the guns that have come through the shop here but this is NOT A DEFINITIVE LIST on which one you need :

-Canadian delivered 8″ & 11″ rifles in .223 / 5.56 = 16mm barrel journal
-Canadian delivered 7.62×39 rifles = 16mm barrel journal
-CZ-USA delivered 16″ (HB) rifles in .223 / 5.56 = 18mm barrel journal
-CZ-USA delivered 14″ rifles in 7.62×39 = 18mm barrel journal

Any other make or barrel you will need to measure and figure out on your own before committing to purchase parts. We will only guarantee that these parts fit and function on CZ made and Dlask Arms Corp. made barrels. Please do not call asking for help on this, we do not give advice over the phone and ask not to be bothered, please and thank you.
