ok :(

i wanted to go shooting today my new grizly but before i wanted to change the stock first.

so i have 2 diffrent stock sets

one is a wingmaster fleur de lys, the other one is a speed feed pistol grip.

the speed feed has a super long screw that is too big to fit in the hole

the wingmaster stock set dosent have a screw included and the grizly one is to short

anyway any advice here ?

i tought it was a 870 prefect clone ?
 
Even within Remington, the synthetic stock bolt is a different length than one from a wood REM stock.

Not sure if it will fit, but maybe the receiver stock nut can be replaced with a Rem one if it's not a different size and if your stock will take the same length of bolt, you'd be in business. However, if the stock bolt is metric, so will be the receiver nut. So you're hooped. China = metric from what I've seen so far. Don't know for sure on the Griz.

They probably make the parts different sizes/lengths 'cause people will try and swap parts and if the parts are a close fit, you'll strip them. If the parts are idiot proof different, they won't fit even close, so parts like screws won't get stripped.

Everybody wants to be different, so you'll buy their parts instead.

A good solution is to fabicate your own screw. Tap n' die set, buy the appropriate length and thickness of rod needed for your Griz and get to it.

I was able to interchange stocks between my Grizzly and Express with no problems.

1. Did the replacement stock work on an existing Remington or did you buy the stock and someone replaced the screw with the wrong one.

2. Take the screw that fits into your Grizzly and go down to the nearest large hardware store where you can determine what thread size it is. They usually have thread guages to assist you in this process. If not try to eyeball equivalent bolt diameters and then try to match pitches by placing the threads of one bolt over the other. Matching pitches will have the major diameter of one thread sit in the valley of the minor bolt thread.
The mountians and valleys will match across the entire length.

3. Once the thread size and pitch are determined (i.e. 1/4-20 vs. 1/4-24 or metric equivalent) then it is just a matter of picking out the bolt/screw that matches the stock length.

All remington butt stocks come with a bolt. I supect the old fleur de lys has changed hands and along the way the bolt was misplaced.
 
I pulled the stock off of my Grizzly and tried a very old Wingmaster stock and bolt that has been kicking around my shop for 10 years and the bolt with the stock fit the Grizzly threads perfectly , they turned in by hand . I sort of like the wood on the Grizzly, I think I will refinish the wood and replace the plastic. I also want to see if it lightens the weight , this is a gun you want to carry a lot and shoot when you need to.
 
I bought a Butler Creek folding stock for my Norinco M870 and I had a similar problem. The bolt/screw provided in the after-market kit didn't fit the Chinese nut...

So down to the hardware store I drove, with the female bolt part in my pocket. Turns out that the only thing that would match the size and thread was a standard ratchet head bolt that was too large to fit (in head diameter) and was not made to be used with screw-drivers.

I had no choice and bought two of the ill-fitting bolts and off to my dad's garage I went. With the aid of a vise and a Dremmel tool, I was able to round off the bolt's head, cut a slant for a flat-head screw driver and cut the bolt's length.

Now everything is nice and tight, just like I like them to be!;)
 
express wood and the factory bolt that came with it fit perfectly on my grizzly. I did have to sand out the inside of the forend a bit since the grizzly forend tube is slightly larger diameter than an actual remington 870.
 
The easy part is .250" NF28 pitch.

The length of the screw, I don't know. I do know they're a difference between wood and polymer stocks.
