You could try t tell the officer its a Fancy Hider / brake rather than a flash one.....???? ;)
Or a breaching attachment
Cool. Will buy a smaller .223 sized one when/if it appears. The prototype I tested was very quiet and nice and light.
Thanks for the comments. All the muzzle devices are A cat compliant. All are closed at the front unlike "flash suppressors" which are specifically designed to "suppress" the flash. I have renamed them so as to not cause confusion. The Cyclone brake performs slightly better inside the can, doesn't need clocking, and will be less obnoxious to those on either side of you at the range. From memory they are only about 1dBA louder than a bare muzzle where the two port brake is about 4 dBA louder but with better recoil.
I am testing the 556 version now and have a mid sized design for up to 6.8. With the brake the can is good for 308 down to 14.5". I will be expanding the range of brake threads to accommodate all barrel sizes. I will even be able to provide 1/2-28 thread for 308 sized rifles by drilling up the 556 brakes.
@ODL do the cyclone 'brakes' require a crush washer on a 5.56 AR15?
What will be the approx difference in dimensions / weight between the current 7.62 can and the mid-weight?
Cheers,
Keep up the excellent work.
No washers are required with the cyclone since it does not need to be clocked. It only needs a minimum shoulder of about 2mm over the thread to square up on. One of the things that worried me about the prototype Gimp tested was the fact that the FH could be installed on the piss by improper use of the crush washer.
The two port brakes are supplied with a shim kit for alignment or you can get a smith to turn down the face for a no shim fit. One customer using the brake with the shim kit and suppressor is getting good results from a DTA. Just less than 1 moa shift can on or off and groups around .375".
Current weight of the 6.8 and 556 as designed in titanium is 155 grams x 165mm OAL and 145 x 150mm OAL. You need to also add the weight of the brake which is around 74 grams in 15-5 PH SS. These may change during testing but not much. The 762 can is well tested and for its size is a very efficient suppressor which provides the same sound reduction as the thread on 762-20. Using M193 556 Belmont in the 762 can with a Colt Commando 11.5" barrel provided 138 dBA average at the muzzle but with a bit more back pressure than a dedicated 556 suppressor. This was tested with the standard front site gas block, not an adjustable.
Here's a couple of pics of the 7.62 version , 5/8 thread , its a elegant & simple design , it slips on and screws on approx 1.5 - 2 turns , and then you just click the collar into the locked posn , which is both marks lined up together & thats it , to dismount , click the collar off the mark & un-screw .
Easier to do than describe .
