Has Anyone Changed the Stock On Their Mossberg 500 20 Gauge?

silver-bullet · January 30, 2008, 09:42 PM

I'm considering picking up a mossberg 500, in 20 gauge. It has a wood stock, and I'd want to change it over to a synthetic stock w/pistol grip (full length). But I notice that most of the synthetic stocks (ATI, Knoxx) all seem to specify 12 gauge. My question is: would these stocks also fit the 20 gauge, or is there a significant difference in the size of the receiver, such that aftermarket stocks are not interchangeable between 12 and 20 gauge? Thanks.

The 20 GA receiver is narrower than a 12GA.

A 12GA stock will bolt up to a 20 GA receiver, but you will have a little bit of an overhang on the sides of the stock (somewhere around a 1/16" - 1/8").

If you don't mind that or if your real good with a dremel tool they'll work fine.

The 12 is a TINY bit wider but many factory guns come with more overhang...
You won't notice it likely.

Bravo. This is exactly what I wanted to know. I may give it a shot (no pun intended), and go with one of those ATI collapsable stocks. I notice on their website that the stocks are described as fitting BOTH 12 and 20 gauge. Hmm....

I have a Knoxx stock on my 20 gauge and it fits just fine. I wanted a bedroom SD shotgun and the stock I have on it is the Knoxx SpecOps Folder.

Computerguysd,
Are you saying the Knoxx stock you bought for your 20 ga was originally made for a 12 ga? How does it fit your weapon? Any pics? Thanks for the info.
