I had the pistol grip spring version and it gave me horrible face slap.
I know it was my hold but that's just the way I hold a shotgun...
Sold the gun and recently put their NRS (no recoil system) on a 12" Grizzly and love it![]()
Just google "blackhawk specops knoxx stock installation instructions"
you can look at the installation manual. it tells you how to avoid the cheek slap.
Below is the text, but i cant get the pics to copy.
IMPORTANT NOTICE: During recoil, the shotgun moves rearward over the pistol grip
slightly more than one inch. To avoid discomfort or “cheek-slap” maintain a minimum
space of 1” between cheek and flare on front of stock. (Fig. 6 & 7) If “cheek slap”
persists, position face further back or extend stock one position.
It is not necessary to pull the stock tightly into your shoulder. Instead, take a firm but
not too tight of a hold of the pistol grip and set the butt solidly into the pocket of your
shoulder. This will allow the recoil reduction mechanisms to function most effectively.
Do not pre-compress the stock. In addition, start out shooting the stock longer than
you think necessary and gradually shorten the stock until you find the correct length setting.
RIGHT: Maintain at least 1” space between cheek and flare in stock. Maintain a
comfortable cheek weld, avoid mashing or pushing face down into stock. Keep head
more upright and relaxed.

without proper eye relief will come back and hit you! Be sure to allow liberal eye relief
of about 3”to 4” to prevent an injury. Do not let anyone shoot your shotgun without
checking for proper eye clearance.
NOTE: When using BLACKHAWK! Knoxx Stocks in conjunction with SureFire® and
similar forends, it is advisable to keep the weak hand back at least an inch from the
lamp housing bulge. This will avoid the possibility of recoil impact on the fore part of
the weak hand when the shotgun is fired.
