Mossberg 590 a1 18"

[StukaJr]

I've jerryrigged the Mossberg heatshield onto a 590A1 - the heavy barrel makes it too wide for screwholes to properly align, so I had to do some rigging with different hex screws and JBWeld... Took spme heavy hammering with a rubber mallet to fit over the front of the barrel - the braised on front sights prevent the heatshield from "slipping" over the front... Scratched park in few places...



Has held for 2 years now - no problem... Wouldn't do it again, but at the time, I had to have a heatshield on my Mossberg and keep a heavy barrel... If it comes apart in the future, perhaps I'll take it off again and just get a spare 590 barrel.

P.S. The parkerizing on Mossberg 590A1's is very weak and scratches off too easily - my loading tube got silver lines on it from test feeding dummy rounds almost immediately...

Added: The current configuration, I'm using SpeedFeed III stock - the SpeedFeed IV, while a good idea, does not work as well in practice and negates benefits of Mossberg design. Grip has to be changed to disengage the safety and completely changed to release action - not a problem with classic rifle buttstock... +4 shell storage is a nice addition, but little cumbersome for tactical reloads - good addition for Administrative reloads though. Make sure to fit both shells though, because when adding only 1 - they fly out with recoil - rather troublesome if using those off-size Eastern European shotshells like S&B.

Looks good. Did you buy the heatshield parkerized. How do you parkerize a gun? Is it simmilar to powder coating? I would love to do mine.

Wow I didnt realize how far back that pistol grip was on the speedfeed stock. I can reach the action tab and saftey from mine.

590A1 comes "parked" from the factory. Mossberg makes 2 types of heatshield - blued and parkerized (stainless steel maybe as well). Parkerized heatshield matches 590A1 exactly in finish - which makes me wonder if they intended it for 590A1 at some point.

Parkerizing process involves stripping the bluing to bare steel, prepping the metal and "boiling" the steel in the parkerizing solution - http://www.blindhogg.com/parkerizing.html has a step by step explanation...

not all 590's have a metal trigger gaurd.mine has a plastic one.there are at least 5 differentones off the top of my head

we are talking about the 590a1 not regular 590's.....the regular 590 has plastic and the 590a1 does not

I believe that metal replacement parts for the trigger guard and safety tang are available from Mossberg - the plastic parts suppose to be durable enough with the exception of extreme hot climates.

You forgot the heavy walled barrel that comes with the 590A1 also

I believe you have to buy a whole new trigger assembly. Also there is no real reason to get a metal trigger guard. The plastic ones are extremely durable.

plastic is not more shock/impact resistant than steel

I was speaking of plastic parts on the Mossberg 590 that have readily available replacements - if I forgot heavy barrel, then you forgot ghostring sights

plastic is not more shock/impact resistant than steel

It's not, but it's "good enough" for the job - majority of the reported failures of both the triggerguard and the safety tang were due to exposure to extreme cold temperatures... Otherwise, the part endures. That said, though, I do prefer steel over plastic any day.

[proraptor]

wrong because you can get regular 590 with ghost ring sights

Do you guys know if the metal trigger assembly for the 590A1 is compatable with a 500A? Basicly could I pull the plastic one out of my 500 and replace it with one for a 590A1?....
