Help Needed!

[LynnKCicle]

Years ago I bought a Tapco Intrafuse TGS-12 Mossberg Adjustable Buttstock and Grip STK54160B for my Shockwave. It has been years since I've fired it, so I took it to the range this week. Now I want to clean it. BUT I cannot remove the trigger group without first removing the Tapco pistol grip, which blocks the trigger group from being removed.. Unfortunately, I have misplaced the instructions and the dedicated tool needed for removing the screw holding the pistol grip to the arm brace. It looks as if it is a hex screw, but an octogon instead of a hexagon. I have tried ever hex wrench I have and none fit; they are either too large or too small.

It also seems that both Tapco and Interfuse are out of business.

If worst comes to worst I'll saw down the rubber/plastic grip so I can use a vice grip to remove the screw. But I'd hate to ruin it. Does anyone have any suggestions???

Perhaps and Allen head?

Could be Torx

If it is an octagon try a square bit.

A damaged screw remover (little reverse threaded tip) may work as well.

Thank you, but I do not think the issue is rust or a frozen screw.

Thank you. I looked at a photo of a Torx on line. It is not the same.

Thank you. I'll try a square bit; if that doesn't work, I'll get a damaged screw remover.

Does it look like this:
If so, it's a double square head and what @Dawico said should work.

Thank you! I found a set of drivers on Amazon for less than $10.00. If they work out, fine; if not, I'll return them and try something else.

Harbor Freight sells bit sets for all of the security bits. Not too expensive. Some on amazon too.

Kidding, kidding...I'm glad you found the right bit for the screw. There's very little I hate more than proprietary fasteners.

Well, I hope it is the right one. If not, it is easy to do returns to Amazon.
