Post subject: Mossberg 590A1 51663 Serial Number range/year

Just curious what year manufacture a 51663 with serial number T086xxx? Anyone recently purchase a 51663? If so, what's your range?
Also, I've read that finish is different for 2007 A1s too? Thanks in advance.

Assuming the numbers go to 999999, then a new letter, your 51663 is 1.5 million units newer than mine, which is in the mid R numbers. Mine was NIB old stock when I bought it. It has the sling swivel stud on the mag cap instead of on the bayo lug like yours has. I don't know what year it was made.

Thanks Austin12Gauge.
Anyone else out there purchased a 51663 recently that could give me an idea about the serial number range?
I'll call Mossberg later, but don't know how helpful they might be about this.
I called Ithaca last week with a number from an old 37 Featherweight and they very politely dated it to 1952 (just two damn years away from C&R!).

Well, Mossberg surprised me. They have a policy of not relaying dates of manufacture or serial numbers over the phone, only e or snail mail. OK, so I sent them my Mossberg serial number list by e-mail and in a few hours got a reply with birth dates for all my guns, cool. The T086xxx is a September XX, 2007 manufacture BTW.

How do you like your 590A1? I keep on thinking of buying one, but I haven't gotten around to it yet. How about a picture?

It's scheduled to arrive with my FFL dealer on Tuesday. Since I have a 50668 (Special Purpose, non-mil spec version of the same gun), it'll be great to compare the two. I'll try to get some photos...

To tide you over until Dub gets some pics of his up-
The 590A1 is a great shotgun. As a recovering green box snob, it won me over.

Post subject: re: Mossberg 590A1 51663 Serial Number range/year

And, as M24's pictures attest, the Mossberg heatshield can be fitted to the heavy barrel M590A1 even though Mossberg says it can't.
Nice pics, M24.

Post subject: re: Mossberg 590A1 51663 Serial Number range/year

Excellent photos M24, better than I'll take for sure. Yours are really the first I've seen that show in glorious detail just how friggin' thick the barrel really is!

Post subject: re: Mossberg 590A1 51663 Serial Number range/year

Here's a better take on barrel thickness; SPX vs A1.

Post subject: re: Mossberg 590A1 51663 Serial Number range/year

Arrived (pics to follow at some point)! R&R shipped the day after I placed my order (maybe they expedite subsequent on-line orders, as my initial SPX order took about 4 days until shipped). Excellent condition, no scratches, rubs, blems, etc.
This gun is surprisingly light -- so much so that I had to compare barrels with my 50668 just to be sure! (Maybe it's because I don't handle my 50668 empty much.) The finish is outstanding, done in what I understand is Mossberg's 'Matte Blue,' a dark, dull black finish, unlike the grey-like park finish on my 50668 circa 2002. I believe the finish of the SPX is the same, but for some reason, not as durable? The matching finish on the SPX Choate tube seems weak, maybe because it's aluminum and the barrel isn't...
I really like the stock on this 51663, actually quite different than the Mossberg Speedfeed featured on the 50668/51668s. The length of trigger pull is shorter than the Speedfeed, great for my somewhat stubby fingers, but the length of pull is standard and fine for my long arms (I've given up on Bantams, which are usually perfect LOTP, but too short an LOP for me, no matter the clothes). The comb is a bit thinner than the Speedfeed, which I like, and the butt pad is more substantial too. I've attached an Eagle 6-round mag pouch to the starboard side and it works well, not interfering with my cheek weld when I switch to that side. I think I'm going to forgo the Speedfeed replacement I had in mind and run this stock...
Anyways, one gripe, the front sight post of my new 51663 is not sitting squarely in the dovetail, slightly left, annoying, given that I've got windage control on the aperature and never touch windage settings after zero. Gotta figure a way to move it without dinging it up (I've got a great front sight blade adjustment tool for Enfield No 4s, but I don't think it will fit here...).
Relatedly, any recommendations for direct blade replacement, tritium? Hans used a direct replacement of the factory blade on my 50668 assembly with a tritium...have to give him a call...
Otherwise, I'm thinking of keeping this gun as is, no side saddle, e.g., that way I can keep it in the Mossberg Loc-Box mounted in the basement, a great go-to when I'm down there doin' the laundry and I forget to bring down my Browning Hi-Power, (plus I would get to enjoy looking at the bold '590A1' embossed on the receiver...

Actually, it is steel too. Choate is just using a not-too-great finish. Granted, I use mine a little roughly and it is not a safe queen but I would still like to see a better finish.

Brass punch + rubber mallet. Just tap it. Not very precise, but it is a shotgun. That is what I used.

Brownell's sells a Meprolight tritium. Pretty good sight.

Most fun to shoot at range. I take the light off and install a plug before shooting at the range.

Run down please: what Knoxx stock is that and either what side saddle is that or what was done to allow the folder to work like it does. Judging from the photo, it looks like the folded stock allows use of the sights in the folded position? I am considering this set-up for my 500 Tactical Cruiser. Thanks in advance.

Stock = Knoxx SpecOps Folder - You can use the sights in the folded position.
Side Saddle = TacStar 6 shot side saddle which I cut the plastic shell holders to 3 and a 1/2 to allow for the stock to fold up. You can purchase a 4 shot version and cut that down. It would be easier. I already had the 6 shot when I got the stock.

Note: The picture shows 4 shot side saddle. I had to cut another 1/2 off to allow for stock recoil.

Post subject: re: Mossberg 590A1 51663 Serial Number range/year

Thanks for that Andersun. I believe the TacStar 4-shot saddle would not solve the problem, as it is mounted in the same rearward position, such that to make the 4-shot work, one would have to remove the three most rearward holders. I think cutting the 6-shot is the only way to do this.
