Receivers are available in your choice of 416 stainless or chrome moly 4140 steel in right, left, and dual port.

Each receiver is inspected for bore diameter and straightness using a Sheffield Precision Air Gauge. This instrument is accurate to 50 millionths of an inch.

To maintain straightness, we machine all the openings in the receiver in hardened steel after heat treating. This is difficult, as the hardness is Rockwell 41-42 C. But, this is done to maintain the optimal tolerances accurate actions require.

Optional dovetail style scope rail.

The dual port model is designed for competetion shooters who desire the advantage of placing shots downrange quickly. It is a left load, right eject micro port.

The micro port opening measures .550 inch in height and 2.040 in length. The receiver has the same footprint as the single port. It is available is either 6PPC or .308 boltface.
