The bayonet mounts will go on any barrel with a 3/4” gas block and .79” of unobstructed barrel rear of the thread shoulder.  

They will only permit bayonet mounting on barrels that would take a bayonet before.  Aka 14.5” govt m-4, or m4A1, 16” HK IAR, 20” A2,3,4.  Thats a spatial length arrangement issue of the lug needing to be a correct distance to the thread shoulder.

The mounts essentially make a reflex K can out of whatever you mount them to.  That means they make the cans shorter in their mounted configurations, a few db louder with more muzzle flash in the suppressor attached configuration.  We make the bayonet mounts in single port brakes and flash suppressors.  

The single port brakes will help flash suppression and noise suppression of the mounted cans remain more optimal.  

The recce 5 has less loss of performance with the bayonet mount than dual lok tubeless cans due to baffle characteristics.

The bayonet mounts are long internally so you have to pay attention to that with some of the plan A combinations as you still need the device to fit inside the can to be useable. The compact HRT is too short internally to fit the bayonet flash suppressor but the brake will work for example.  We have a special military model that is longer that will take the bayonet flash suppressor.  It was produced in sample qty only for demonstration purposes and is essentially a technology demonstrator.  So its lack of availability is not reflective of our withholding it from anyone.

For training purposes the flash suppressors feature a BFA groove for std affordable blank firing adapters and USGI insight bore sight collimator compatibility is retained.

Our M4-SD series is also compatible with bayonets.  We have made a new closed tine flash suppressor for those that is also compatible with a std issue BFA, and the bore sight collimator, and has a three position wire/ rebar cutter on the muzzle end.

The closed tine flash suppressor is also being made for taper mount and dual lok, but not currently in a bayonet compatible version.  It does however accept the BFA in the dual lok 5.56mm version only. Bore sight collimator in both mount versions and both calibers 30 and 556.

The other page for the taper mount version hasn't been made, this one wasn't listed because the marketing department wasn't sure of pricing.  I didn't have a discussion about pricing, I just made the page visible.  I think the pricing might be solid where that's at.

This stuff is always odd, because I work on stuff months and months before it ever shows up, and sometimes people don't know about it, or know about it and don't carry it through, so it doesn't get completed to the simple point of "Showing up", even though its here and ready to ship.

Hey I'm sorry for the bad news, someone reported to me that the taper mount bayonet brakes ONLY are waiting for shipment to PVD coating.  They will probably be a month, and cost $119.95 MSRP.

I think OAL is ~2.4" on that model.

The relevant dimension is distance to the blast baffle in the suppressor that needs to be compatible.  That's where the OAL of the muzzle device can provide interference of fit.  Otherwise the 2.5" dual lok bayonet flash suppressor for example, is shorter than an A2 compensator in the mounted configuration by about .12"

I don't have a hosting platform for photos and my photos would suck.  Brooke at Griffin is a photographer and has a hosting platform.

Sorry no action yet.  It was a military thing we are selling to whoever has money.

I think the brakes are cool for consumers where bfa’s and bore sight collimators don’t matter so much.

Something will probably happen.  So your not wrong.

You don't have to like stabby things to use a bayonet micro brake.  That's just shorter OAL mounting of a suppressor you already own.  Turns cans into a mini-OTB can.
