Converted my 590 Cruiser

I liked my Mossberg 590 Cruiser, but with the pistol grip only set-up I didn't get out and shoot it very often. So, I picked up the Blackhawk Knoxx SpecOps adjustable stock this afternoon. Installation was a breeze.

Here's a pic from before...

...and with the new stock...

Here it is with the A1...

The new rig is a much more practical for me and it'll get a lot more range time now.

Just installed a receiver rail and a Sightmark Mini Shot holographic reflex sight on the 590. Picked it up for $80 w/free shipping at

The Sightmark series of reflex sights are designed to create a lightweight, yet accurate, sight. Sightmark reflex sights are able to handle heavy recoil, will stay zeroed in longer than competitor's reflex sights and are perfect for shotguns, pistols and rifles. The Mini Shot™ is the most compact in the Sightmark line; it is lightweight and extremely accurate for its miniature size. This reflex sight features a 3 MOA illuminated dot reticle and is useful for most any application from close quarter combat situations to hunting. The Mini-Shot's compact size makes it perfect for use with handguns and shotguns; which can then be utilized for home defense, target shooting, or turkey hunting. To create the ultimate weapon, mount the Mini Shot alongside a riflescope in order to quickly acquire targets at close distances while utilizing the riflescope to engage targets at long range.

Initial impressions:

This thing is tiny! It seems very well built despite its size and the 3 MOA dot is VERY crisp. The two brightness settings make for quick adjustment depending on your lighting conditions. It has a light censor that when you put the hood on, switches the optic into sleep mode.

As for performance, this thing is a little beast!

What it lacks in size it more than makes up in results on target. Windage and elevation adjustments are made with a small screwdriver. Took me about five shots to get her dialed in and I was punching holes where I wanted em in no time. Here's one of my 50 yard targets using Centurion 2.75 inch, 1 1/8 oz slugs. Ten rounds went into this one...

Put 50 rounds down range today with no movement or vibration in the optic or mount. I highly recommend the Sightmark Mini Shot to anyone looking for a great, affordable reflex red dot.

What muzzle break is that? Can you post a close up of that?
looks like a factory Mossberg breacher barrel.

Yup, it's the factory breaching/stand-off device on Mossberg's 500/590 breacher barrel.

Here are some close-up shots...

Thanks, now I need to find that barrel!
Very nice!

Last time I shot 50 rounds of 12ga at one time I had a bruise on my shoulder that was like four different colors!

Gotta love the SpecOps stock!

The recoil reduction system works like charm. My shoulder was a little tender, but no bruising at all. I could have put another 50 rounds through it on the day without a problem.

you'd honestly be better off to just but a complete gun with that barrel.

you'll spend about 200 bucks on the barrel alone I think.
I've got to try one of those sights on my desert eagle or my saiga 12!
Your conversion with this stock is excellent. I don't want a 12 ga. pistol, however a 12 ga. with a stock similar to yours makes a lot of sense.
