I have sent off the paperwork for my first suppressor and am in the long waiting process. The rifle I am putting it on is home built (specs below) and is currently running perfect. All casings eject around 4 o'clock. I don't have an adjustable gas block and wanted to ask the guys with experience how I can tune this to run without being over-gassed once the suppressor is mounted? I can't change the gas block as the AAC Blackout is pinned as it is a 14.5". Should I have a set of different weight buffers and a wolf extra power spring to tune this or is there another way?

There are a few old school and proprietary tricks of the trade I've learned from old school smiths to customize the flow of the gas from the port to the operating system, and Colt's also been developing a modified DI system (something about a sleeved gas tube?) that makes gas port erosion irrelevant... so there are ways to customize the amount of gas going into the system once you've developed a build.
However, with a QD can, your gas port pressure will vary wildly, and most methods of customizing gas flow are relatively permanent. The only quick adjust methods I know of are the Switchblock, MGI adjustable gas tube, and the soon to be released WAR upper receiver. You will either need to get a switch block or similar, or just learn to accept the fact that with a suppressor on, your rate of fire and wear on the gun will increase. One method I saw on TOS was when the owner of said TOS built a custom upper with the gas tuned to be able to cycle the rifle (but not lock back on an empty mag) reliably without the can, but not so much as to be overgassed. This type of work is very expensive as it either requires a barrel blank, cutting down and re contouring an existing barrel, or using the fore mentioned proprietary methods mentioned above. All are time consuming as one need to experiment to get things "just right". Most people just learn to deal with overgassing, haha. This is a off the shelf build with a Gemtech Trek permanently attached to a stock Daniel Defense 11.5" barrel. Even with a Colt X Buffer, this gun's running very, very fast.

| Thanks guys! I wasn't thinking this through all the way when I built it :( Now I wish I would have used the SB. I have plenty of time to figure this out as I just sent my paperwork in 3rd week of Jan. I might pick up the Noveske 16" barrel with switchblock from Ranier and sell my current barrel. |
