I ended up making the 9/16x24 before these but will get these done over the summer. They will be 3 and 4 ports with 1/2x28 threads. The length varies a bit, because they are adjustable, but they are roughly .100" longer than the 1 piece version fully collapsed and weigh just under 1 oz more than the 1 piece version. These will be .800" OD and the back of the cap will taper to .750 to match up with the many AR barrels made. They will have the same port size as the current 1 piece Lil Beast brakes.
I have these done in 3 and 4 ports with 9/16x24 threads. You can see that the cap is the same diameter as the brake on these. The 4 port in the picture has the cap backed off 1 revolution (or the max it would need to be backed off). These are a max port brake, since they can't be turned down, so the port size is only about .025" shorter then a normal 1 piece Beast brake. That will make them more effective then a standard 1 piece Lil Beast brake. The 3 ports weigh 3.0 oz, are 2.32" long, and run 98.50 shipped. The 4 ports weigh 3.7 oz, are 2.77" long, and run 103.50 shipped.
The 3 port version is 2.76" long (fully collapsed), 1.01" OD for the brake and 1.075" for the cap, and comes in 5/8x24 threads. The back of the cap is tapered to 1.0". These weigh 4.2 oz and are $98.50 shipped
The 4 port version is 2.76" long (fully collapsed), 1.01" for the brake, 1.075" for the cap, and come in 5/8x24 threads. The back of the cap is tapered to 1.0". These weigh 4.9 oz and are $103.50 shipped.
I will make a 5 port version when I do the next run of these. That should be around March/April.
These are only available in 4 ports with 3/4x24 or M18x1.5 threads. They are 2.80" long (fully collapsed), 1.1" OD for the brake, and 1.165" OD for the cap. They weigh 5.8 oz and are 113.50 shipped.
