I have four AAC rifle suppressors including an M4-2000 and 762-SDN-6 that use the 51T interface. I also have the MK13-SD and TiTAN-QD that use the 90T interface. They're very good suppressors in terms of noise reduction, durability and precision, but the interface is marginal due to the inability to keep the suppressor tightly connected to the rifle. A coworker managed to send his 762-SDN-6 downrange last year due to it working loose. I have a number of Dead Air suppressors that have an excellent QD interface (best I've used) and have a couple of SilencerCo suppressors that use what I would describe as an improved version of the AAC system.
This week I sent off the M4-200 to be modified to my specifications. I created models and drawings of the AAC products I have and came up with a better interface that gives the owner a number of good options. I won't say much more about this until the M4-2000 is back and I've had a chance to test it, but if all goes as planned I expect to be able to talk about a significant upgrade to AAC suppressors that use the 51T and 90T interface. My priority is to fix the four products I have so that I enjoy using them, but I've also thought about offering an upgrade service if all goes to plan.
