BlackHawk Products Group has added two new thumb-hole stocks to its line of Knoxx rifle stocks that employ an ergonomic pistol grip to improve accuracy, according to the company.

The Knoxx Axiom TH and Knoxx Talon thumb-hole stocks improve accuracy, target acquisition, firearm steadiness and comfort in various shooting positions, according to BlackHawk.

Using the new two-stage dual Knoxx recoil compensating systems, the Axiom TH has the ability to reduce felt recoil of even the most potent rifle rounds by up to 85 percent.

The stock arrives with interchangeable rubber grip inserts that adjust the overall size of the pistol grip. The barrel channel is a full-float that will fit any barrel diameter. The unique design of the stock cuts muzzle rise and uses a traditional comb design. The receiver is compatible with bi-pods, and a 14-cubic inch rear storage compartment is located in the butt of the stock for small items.

The Axiom TH is available in black polymer or universal camo for the Remington 700 BDL - short and long action, and the Howa 1500/Weather by Vanguard BDL for short and long action. Retail is $269.99 for the black polymer and $299.99 for the universal camo.

The Knoxx Talon stock features Knoxx's dual-recoil compensation to reduce recoil with all loads and eliminates shoulder fatigue and related recoil injuries. The Talon is made from polymer and alloy construction to cut muzzle rise, so shooters can get the gun back on target faster, according to BlackHawk.

Interchangeable rubber-grip inserts allow the shooter to adjust the overall size of the grip for a custom fit. A rear storage compartment of 14 cubic inches allows small items to be kept safely and securely. The Knoxx Talon is available in black polymer and universal camo for Remington 870 12- and 20-gauge shotguns, and pump/semi-rifles, Mossberg 12-gauge pump varieties and Winchester 1300 12- and 20-gauges. Retail is $144.99 for the black polymer stock and $169.99 for the universal camo stock.
