    Is a 10.3" barrel ok to suppress?

    Hey guys I had a problem that came up when in the process of putting togther my sbr build. I originally wanted a dd mk18 upper. However, after speaking to a few people I am wondering whether I should go for the dd mk18 which has a 10.3" barrel, or buy a 10.5" mk18 upper buy another manufacturer. I guess the question is, can I reliably suppress a 10.3" barrel? I have a YHM phantom LT on a form 4 to mount onto the sbr. Anybody have any hands on with this setup or a similar set up?

    An email from YHM I received they will not warranty their suppressors for anything shorter than 11" for 5.56 and 12" for 7.62. With that said though I know some that have used shorter barrels in both calibers. The concerns are blast from the shorter barrels wearing the baffles prematurely and the bullets not stabilizing and causing baffle strikes.

    It depends on the suppressor (both manufacturer and model).

    I recommend the AAC line, especially if you want a 10" barrel.

    AAC's M4-2000™

    or if you want a multi-caliber silencer (recommended), the 762-SDN-6™

    Both are warrantied for a 10" barrel on 5.56mm

    I might suggest this; made for 10" and smaller in 5.56.

    Does 0.7" really make that big of a difference in stabilizing the bullet? Not sayin I would, but how the heck would they find out if the length of the barrel I used on the can was less than 11"?

    Mostly when you try to get it repaired under warranty as they ask bout the host platform. For SBR lengths "longer" is generally better as it gives more time for the powder to burn out and the gas to escape. Less blowback, less heat/debris in chamber, stabler ROF, etc.

    I have been shooting my SDN-762 regularly for a few years (think: tens of thousands of rounds) through my 5.56 BR (7.5" barrel) and have had ZERO issues. I hope this helps you make a decision.
