How to Measure Your Barrel Contour

Action length is the distance between the front and rear action screws. These screws are found on the bottom of the stock fore and aft of the trigger and magazine/loading port, which hold the barreled action to the stock.

When taking this measurement remember to measure from the middle of one hole to the middle of the other hole. Also, do not mistake the trigger guard screws for action screws. Since the difference between a short or long action can be as little as ½-inch either mistake can be critical.

Another means of identifying action type- is the cartridge type. In most cases cartridges measuring less than 2.8″ will utilize a short action. Long actions will not exceed 3.340″. Calibers larger than this will generally use a magnum action, or a special purpose action specifically designed for that cartridge.

More Information Below.

Peak 44 stocks are based on a tapered Sporter Contour. Tapered contour barrels have a radius that starts 2.750” from the breach and creates a smooth transition to each taper diameter. Options include #1 #2 and #3 contours. The Sendero Contour is a custom sporter sized between #3 and #4 Sporter.

The negative comb reduces felt recoil and allows the shooter to maintain proper form. This is vital for target acquisition and follow up shots.

Carbon Bedding Block

Bonded to the outer shell and working in tandem with a set of aluminum pillars, this slip of carbon takes the place of a much larger and heavier aluminum bedding block. The carbon bedding block allows recoil impulses to transfer directly from the recoil lug of the action to the outer shell of the stock, enabling the use of lighter weight fill material throughout the stock shell.

Advanced Ergonomics

The Bastion’s grip combines a relatively thin wrist with a healthy ambidextrous palm swell and a substantial thumb groove to promote proper form while shooting.

3DHEX Recoil Pad

The 3DHEX recoil pad kills recoil unlike any pad on the market today. The first recoil pad to employ additive manufacturing at the production level. The set of collapsible voids function to stretch the time component of recoil, making that sharp kick a soft shove.
