Blackhawk / Knoxx Thumbhole Stocks
Knoxx (now part of Blackhawk) have launched a thumbhole variant of their recoil dampening Talon (shotgun) and Axiom (rifle) stocks.
The Talon is available for the Remington 870, Mossberg 500 and Winchester 1300. The Axiom is available for the Remington 700, Howa 1500 and Weatherby Vanguard.
Murdoc has more info about the Talon and Axiom over at GunPundit.

I ordered one of these in March ‘10 and was told they were back-ordered, with delivery in April. In April I was told May, and now I’m told (from Blackhawk) ” Our design on this product is taking longer than expected as we are doing much testing to make sure we have it just right. It’s looking more towards August possibly July. If you need anything please let us know.” Signed [Blackhawk salesperson]. Anybody know what’s going on at Blackhawk? Should I cancel my order? Was their initial production defective and is now being re-designed? It looks like a good stock for my Rem 870 but I’m not sure now. Any info would be helpful.
The Mossberg 500 Knoxx Spec-ops stock can be readily adapted to the Saiga 12. Just google “knoxx saiga”
I was interested in these until I ran into Zak Smith’s opinion after evaluating one–his opinion: absolutely terrible for accuracy.
I think this is a very cool idea, and I actually like the way it looks with this new design.
Knoxx needs to come up with something for the Saiga 12.
