Surefire forend recoil reduction mod

[rodregier]

Some people have problems with the Surefire pump action shotgun forend smashing their support hand index finger. I have experienced this myself.
I suspect persons with longer arms encounter this more than users with shorter arms. I'm not impressed with the suggested solution of "grip the forend further back".

I had an idea about a possible solution.

Use a piece of 4x4" 0.5" thk
Durometer 50 OO Sorbothane w/self-adhesive backing.

McMaster-Carr #8794K112 $9.82 ea

http://www.mcmaster.com/

(60 to 90 OO is used for shooting shoulder pads.)

50 is more easily deformed than 90 OO.

Cut out to fit the triangular rear-facing surface
Of the forend, and stick on using the integral adhesive.

Will provide a recoil cushion for the off-hand index finger
When cradling and operating the forend from the underside.

Thoughts?

My arms are actually shorter than average, and I used to encounter this with my Surefire forend. Granted, a lot of it was due to my Knoxx stock kicking back a couple inches each time I fired.

My solution was to sell the Surefire forend, and go with a Streamlight TLR-1 mounted on a Remington 870 adapter, with a Hogue forend for comfort. Works just as well, costs less, and my left forefinger isn't bruised after shooting it.

Since no-one could find fault with my proposed design, I've ordered the Sorbothane to try the mod. Decided to go with the most easily deformed Sorbothane (40 OO) from McMaster-Carr. If I'm really lucky I may be able to get 2 pads out of one 4x4" piece.

Found the forend recoil attacked my off-hand index finger both
with and without a Comp-Stock buttstock.

If this mod helps I'll tell Surefire about it.

The Surefire forend hurts my left (support hand) thumb. I have to move my hand forward on the forend - so that it's always pressing the light bar - to avoid dinging up my left thumb at the edge of the nail.

Let us know how your solution works out.

McMaster-Carr declined my order.

The claimed reason:

"Thank you for your order. Unfortunately, due to the ever increasing complexity of United States export regulations, McMaster-Carr can only process orders from a few long-established customers in Canada. We sincerely regret any inconvenience this causes you."

My response:

"If your web pages had indicated this to begin with,
I would not have tried to place an order.

Suggest updating same."


I suspect the real reason is that it's not enough dollars for the export paperwork. I would have preferred an honest answer or an offer to process my order with a surcharge for the export paperwork.

Sorbothane isn't on a controlled materials or products list to my knowledge.

Working on Plan B and C for the Sorbothane...

I'm getting really tired of this BS. It's becoming easier to source many products from European vendors than US vendors because of real or imagined export barriers. How pathetic.

Received the 50 OO Sorbothane from my US purchasing agent L-)

Cut out a suitable piece, feels promising. Waiting for opportunity to perform live-fire test drive. Perhaps this week.

A single 4x4x.5" piece of Sorbothane can potentially make 4 forend hand pads,
since you only need to trim down a 2x2x.5" piece.

Having issues with the factory self-adhesive backing effectiveness, examining options. The Sorbothane is pretty weird stuff, suitable adhesives are tricky.

Got a chance to test the Surefire forend hand pad concept. Definite improvement over the "naked" Surefire forend. Getting the pad to stay put is still a problem. Used a piece of electrical tape to strap it to the forend as a workaround to permit testing.

My Surefire forends, including the 10 year old + one never beat me up as I recall. The Hogue 12" stock gives me a fat lip with out a raid vest on , so I added 3/4". I shoot quite a bit with them too- maybe 2500 rounds a year. I take off the light during day light training BTW.
