I have just picked up a Sinclair, Inc. rifle built on a 40x action. It is a .308/.334NK, 11.75 twist 24” barrel in what appears to be a M24 contour. It’s slick as snot and the original 40x trigger has been tuned to perfection.
I originally thought the stock was a McMillan HTG as it is definitely a M40A1 pattern stock, but it doesn’t feel like any McM I’ve handled. It weighs a scant 29oz and has a Pachmayr basket weave pad on it. It is definitely painted fiberglass, but the butt sounds hollow. It is full length bedded, and has held up well over who knows how long. The tang area is also deep, requiring a very distinctive safety relief cut.
Does anyone know what type of stock Sinclair used to build on, or know who made this one?
