300 or so
Your question can't be answered as written. What Model? What are ALL the markings? What gauge? How long is the barrel? What type of finish? Mossberg 500C, 20 gauge, 26" accu-choke, serial number K064007, checkered wood stock, blued barrel, vented rib barrel.
No, the Mossberg 500 barrel does not fit the Mossberg 600. The two models have different designs and specifications, which means their parts, including barrels, are not interchangeable. If you need a replacement barrel for a Mossberg 600, it's best to look for parts specifically designed for that model.
It is the rifling in a mossberg rifle barrel.
Yes, the Mossberg?æ500 20 gauge ammunition can be used in the Mossberg .410 model. To find out if ammunition will fit, the Mossberg company stamps the size needed on the side of the barrel.
Yes, you can....but the chamber on the 500 barrel is only bored for 3" max shells. You won't be able to fire 3.5" shells through the 500 barrel.
no
Mossberg makes an 18.5" personal defense/home defense/slug barrel for the 500 .410. The cost is approx $75 delivered via fedex. You should contact Mossberg directly to place the order. It's cheaper than Brownell's, Midway USA, Bass Pro Shops, etc. They get them from Mossberg to sell to you at a higher price.A NOTE OF CAUTION: Mossberg does NOT, repeat NOT recommend using slugs through the standard full-choke barrel. Using slugs in this barrel could bulge or burst the barrel.
No
