Thatwayer Mac11 Sound Director

THIS IS NOT A SURPRESSOR - This redirects sound forward rather than back or to the sides and does not change the sound profile.

If you have a mac11 that doesn't have the course threads at the base of the barrel like the ones sold by Aves, then you usually can't have a cool flush mount muzzle device. Both are 1/2-28 threads. 

Here are two. 

Handguards fit over the smaller one and it does not block picatinny rails.

The Thicc Johnson Edition will block both picatinny from the front and will not fit with most handguards/shrouds. 

Print and use at your own risk. 

I have zero suggestions on how or what to print this out of. Make your own educated decisions on what works best for your application and safety.
