Mossberg stock questions

[colostomyclown]

So here's the deal, with pictures to follow , bear with me:

Had a 590a1, came with a speedfeed stock. Decided to put a wood set on it. Ordered wood set. Speedfeed had a bolt, and two lock washers.

Bought a 590 mariner. Came with synthetic stock with stock bolt, larger flat washer and one lock washer.

I'm wanting to use the wood with the A1, and the Speedfeed with the Mariner. Stock bolts are the same size, so I'll swap those, but the oversize flat mariner washer won't fit into the speedfeed bolt hole. Does it really matter what I use, as long as I have two and the fit snug?

How should I proceed?

you should be fine without it. if your worried about it go buy a smaller washer or use one of the old lock washer

Just go to your local hardware store and get a washer with a smaller OD for the Mariner...so regular washer, lock washer.

Really nothing required beyond the regular washer, though...most guns come with only that. Stock bolts with lock washers are the exception.
