Click to enlarge<B>Benchmark Expansion Chamber

The newest version of what is probably the finest quality expansion chamber ever! Precision CNC machined 6061 T-6 aluminum in satin black, or optional polished anodized finish. The new BMI expansion chamber is a little shorter so that it doesn’t stick out below the bottom of the grip frame. P.C.R.I. 4 Star rated. Benchmark invented this style, and still builds the best! Don’t be fooled by cheap copies.
