    The BCM PMCR hand guards also fit great.

    They have a smaller profile and a larger hand stop, both of which are excellent features for a PDW.

    We have not tried that system, but most reviews say it is fairly normal and works with most uppers.

    Size wise, it certainly would be a good combination when used with the PDW barrels.

    The 16" LPR was 24oz and the current 16" HFCL is 26.7oz.

    It just doesn't seem like a big enough difference to be worthwhile.
    No worries! Any plans to do something in the 12.5-12.7" range with the EXC gas system? I might just go shorter instead of thinner, if you catch my drift.

    Hey Clint,

    I have a barrel thats a 14.5 Mid with a 0.625 GB and a 0.077 gas port. Now that I reload only 556 pressure loads and will only be shooting this barrel unsupressed; what size gas tube would you recommend?

    As promised, here is a PDW barrel with the PMCR hand guards and a Covert Comp.

    The Covert Comp is highly recommended to direct blast forward if not using a suppressor mount.

    Does anyone have an accuracy report on the BRT CHF 16" barrel? Looking to build a DMR upper after being inspired by Molon.

    Just ordered one myself. If it is anything like my 12.5, accuracy will be phenomenal.

    My only problem is that I am a moron and forgot to order the gas tube with it.
    Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.
