Mossberg 590A1 *Updated Pictures*
*Updated pictures with a Hogue O.M. Stock which helps out with the weight issue by bringing the shotgun closer to the body due to it being approximately 2.5" shorter than the factory stock. I also replaced the light module on the Surefire forend with the new LM1 model.
This is my parkerized Mossberg 590A1. It took a little bit of modification to get the Surefire and heat shield to fit, but well worth the time. Specs: Hogue O.M. Stock *new* Surefire tactical weapon lite w/ *new* LM1 module 9 lbs unloaded...yes it's heavy :( 8 plus 1 rd capacity Factory 20" heavy walled barrel Mossberg heat shield Burris Fastfire II red dot sight Tac Star 6 rd side saddle http://farm6.static.flickr.com/5282/...7dfc19e1_z.jpg http://farm6.static.flickr.com/5008/...3b57da63_z.jpg |
how did you manage the surefire? is that a different bezel?
|
The forend is the Surefire model# 623LFG. It came as is, and I did not have to replace any parts. As stated by Surefire, some modification is needed to make the forend fit correctly. However, I decided to modify the forend instead of their suggestion of modifying the bayonet lug. I used a dremel with a cutting wheel to grind/shave down the slide tube stop on the inside of forend. I took off a little more that a 1/4" to make the forend and the slide tube flush in the rear. This created enough of a gap between the flashlight and bayonet lug for full weapon/light function. I reversed the stock slide nut to secure the forend to the slide tube instead of trying to find a washer to fit the gap created by shaving the forend. I attached a few photos...

nice looking shotty there mang., but that folding stock hurts like a mofo
|
Sick! Hope to see you at the range one of these days :)
|
Awesome, thanks for sharing, I am pretty sure I haven't seen anyone do that mod before, pretty straightforward and you didn't have to remove much material it looks like. Time to start saving up for the fore end.

No problem, always happy to help.

That is one cool 590A1 there. BADASS!:cool:
|
thanks :D
|
Which heatshield did you use?
|
I used the factory Mossberg heat shield off of their website. However, it's hit or miss... My friend has a 590A1 like mine(a little older), and bought the same heat shield off the Mossberg site and it did not fit.

Genius! Well done, a very nice looking 590A1. :cool2: |
Thanks! The only draw back to the heat shield and surefire is that my moss weighs 10 lbs unloaded! hahahaha
|
That's 10 lbs of zombie smashing goodness!
|
is this the one that is sold at big 5? I was looking there today.
|
love that parkerizing, really nice 590A1, I'm beginning to really like this over the 870. again, well played.

Just finished Brent_MPK's Surefire mod on my Mossberg. Only needed to shave/grind off slightly more than 1/4" inside the Surefire. Mossberg 590A1 (#51663) Surefire 623LF Mesa Tactical stock kit (w/ Endine recoil buffer) |
huh, looks like the new LM series with one battery and shorter profile would also adress this now. That being said, i'll be keeping my eye out for a deal on any of the models because of this mod.
|
yeah, i just noticed that myself on the Surefire website. i guess they were just waiting for me to buy the forend that needed modification!
|
How does having that lug and potentially the bayonet effect the light? I'm going to be doing this to my 590a1, and am glad theres a way to do it without taking the lug off. Thanks for showing us how!

Very nice SG guys! I'm jealous!

Anybody want to make a tutorial on how to do this? I'm a noob and still am lost as to where to dremel and where not to...

I decided to go with the 200 lumen 623lmg instead of the 100 lumen 323lmg (lumens don't always tell actual flashlight output, but it is the same company..). I'm hoping to not need to do much modification. |

Well, I suspect that the 6 series LM that I ordered may be too long. I think that it is the 2 cell vs. 1 cell that makes the difference. I guess that I'll be finding out when the unit arrives.
I still think that the 2 cell is a better idea even if I need to modify (thanks to the OP for this mod-it looks like just the trick). 100 lumens vs. 200 lumens just seems like a no brainer. That being said, the bezel design looks to be a bit differnt on the LMs...Perhaps it will clear after all? It would be interesting to hear from someone who has mounted the new 6 series LM to see if it clears. I have a message into Surefire as well, but who knows how long it might take to figure this one out. |

http://i759.photobucket.com/albums/x...0409-19251.jpg I suspect that this is related to the fact that you needed to grind 1/4inch off the forend, but I installed the 623LMG and it seems to be sitting about 1/4inch forward on the slide tube. The LMG series bezel is a bit more sleek, and it clears the bayonet lug however it does so just barely. I was wondering if there was something hanging up the forend (ie. if it somehow slid forward after I attached it, but before I could get the forend nut back on)? I didn't have a forend wrench and don't really want to risk the screwdriver again. I somehow managed to not ding up the nut or the barrel, but I'm not counting on continued good fortune. Unfortunately no local shops carry the wrenches... Sorry for the low quality Blackberry photos. My son ran off with my camera. |

No, that is sitting correctly. The rear of my Surefire looked exactly like that before I did the mod. I do not have the tool for the lug nut either, and instead used a strap wrench to tighten/loosen the nut. The grinding/cutting is not to difficult with the dremel if you want more clearance. |

You saved me from removing everything again just to make sure. Thanks! |
