Reduced load for suppressor

[grayfox]

The problem you have may be related to direct gas blowback that a suppressor does to ARs. Its increased backpressure and dwell cause gas to blow back directly over the case into the bcg area. The only way I've read to handle that differently is to get a bleed-off gas block that blows some of the gas forward, thus out of your face; they are mentioned on here but I've not used one. As to gas flow down the gas tube, either an adjustable gas block or an adjustable carrier like the Bootleg model. More closed for suppressed, more opened for normal non-supp.
