Special Tool for Blackhawk! Forearm

Have installed a Blackhawk! SPECOPS stock on my 12ga. Mossberg model 835.
The instructions say there is a special tool needed to remove the slotted forearm retaining ring on the Mossberg 835.
Did some internet research and found a company that sells one for $35.00
Seems like a lot of money for a one-time use.

Has anyone installed the matching black forearm without purchasing the tool?

If so, how'd you do it?

Re: Special Tool for Blackhawk! Forearm

That is just the regular spanning tool. It engages the two slots on either side of the mag tube hole.

You can certainly make one easier than $35. Also if you are careful you can take a soft metla punch and gentle hit either side of the slot to unscrew it. Usually they come off without any denting.

The tool is just piece of flat stock, surprised with the $$4 of that stock they didn't just give you one. the 870 is similiar but a slightly different dimension. Getting to old wood forend off can be tough, after you get the nut off.

Re: Special Tool for Blackhawk! Forearm

I just used a small flat screwdriver and a hammer. A small punch or something similar would work as well. My 835 is about 18 years old and came with the wood stock so the new forend reguired a lot of internal modification to work with it. I was aware of the issue before I bought the new stock so I expected a level of effort to get it to work right.

The other thing I might add is to shoot a fair amount of low or high brass shell through it to help "break in" the stock. After a hundred rounds I've noticed a signifigant improvement in the recoil reduction and travel.

Re: Special Tool for Blackhawk! Forearm

Am going to try the flat screwdriver and hammer method this evening.
Gotta ask: how much modification is needed on that forearm?
A gentleman on another site said that after installing the Blackhawk forearm, he took it off and reinstalled the original one.

Good tip about the "break in " period -- although it helped somewhat with the 3.5" shells, I'm not impressed.
But, will try some other shells (2 3/4") to stretch that spring.
Am looking to use this for turkeys and yotes.

A potrion of the rails inside the new forend may need to be removed for it to work. If you 835 is newer then you may be fine.

I wasn't impressed with the recoil reduction at first. After shooting some clay pigeons with a friend I began noticing more and more movement. After a hundred rounds we could notice a signifigant difference in recoil, with low brass shells, versus his 870.

I used a pair of needlenose pliers that I spread out into 2 of the grooves of the retaining ring when I replaced my 870 stock.
