The stock that you choose to use will depend on the type of hunting/shooting that is conducted. Here is a small breakdown:
The McMillan A4 is the stock we use on the Heavy Tactical. This is a heavy stock that is designed for rifles with heavy #6 and #7 barrels as well as shooting in multiple positions, but is typically used in the prone position. It is ambidextrous, has an adjustable cheek piece, length of pull adjustment and a vertical grip.
The McMillan A3 Sporter is the stock we use on the Long-Range Hunter. This stock is a midline stock that can be used on a long range precision rifle as well as a hunting rifle. It features a ambidextrous vertical grip, high comb, and comfortable forend for both shooting offhand as well as with a bipod.
The McMillan A1-3 is the stock we use on the medium tactical. This is a step above a conventional stock and is geared towards the heavier #5, #6, and #7 barrels. It is a good all around stock with a higher comb, ambidextrous, and a comfortable traditional pistol grip.
The Brown Precision is the stock we use on the Mountain Hunter. It is strictly a hunting stock and designed to be used with #3 and #2 barrels. It has unique properties and design that help reduce felt recoil with the larger magnum calibers. This is an ambidextrous stock.
The McMillan Hunter is the stock we use on the Sport Hunter. It is a hunting stock with a higher comb, Monte Carlo type cheek, palm swell, and narrow forestock. This stock is for the #2 and #3 barrels.
The chassis stocks are highly modular and are very heavy. These are machined out of billet aluminum with plastic and steel pieces. This is modular in that the butt stock, forestock, rail systems, and adjustments can all be changed or replaced. A heavy tactical chassis will typically weigh around 18-20 lbs with a scope.
