From properly managed dwell times for SBRs, to running suppressed, or setting up a balanced patrol carbine, we have incorporated your needs into our engineering. We have successfully accomplished this by selecting the right twist rates, gas port diameters, and barrel materials for the barrel we are making (not a lazy blanket method).
