Overview
The Kaw Valley Precision 9mm Blowback BCG uses an 8620 steel carrier with a Nitride QPQ finish. It weighs 14.5 ounces, works with Glock- and Colt-pattern magazines, and uses a heavy firing pin retaining spring. Kaw Valley Precision recommends a mil-spec fire control group for the most consistent results because some drop-in triggers can be temperamental in blowback systems.
In an August 2026 bench test, this BCG ran the Partisan Disruptor and Triggered Company LAT cassette FRTs without weight modification. That result applies to cassette systems only. Selector-style forced reset systems still require the internal weight to be notched or a pre-cut carrier.
