How Much Would You Pay for a tactical replacement receiver for a pump/semi shotgun?

    Envision a CNC machined high strength alloy receiver for shotguns, there would be a version for the Mossberg 500, FN SLP, Remington 870, and Remington 1100 series.

    This is a receiver designed to provide a more modern shotgun platform for tactical shooters, competitors, military and law enforcement. It has modern lines (think the billet lowers for AR15s, very sci-fi in a way), and features:

    -Flattop MIL-STD-1913 rail machined directly into the top of the receiver and extended 6" beyond the receiver over the barrel (a reverse-cantilever design). This would be very similar to the flattop rail of an A4 configuration AR15, but with the extension that goes past the receiver. [in order to achieve this and clear the barrel the receiver, integral rail included, would be a little under a centimeter taller than a standard factory receiver].

    -Ambi QD sling mounting cups positioned near the rear of the receiver on both sides of the gun.

    -Two piece (870 and 500) or one piece (1100, SLP) 8 or 10 round magazine tube with integral (machined in) MIL-STD-1913 rails on the end of the magazine tube nearest the muzzle (positioned so as not to impede cycling the pump, etc.). Includes machined ambi QD sling cups.

    -Forward iron sight rail that is attaches to the magazine tube and wraps around the barrel, positioning it in the expected place (this allows for the use of rail mount BUIS without modifying the barrel of the shotgun in any way).

    -Optional mix and matching of stocks (you could order an FN SLP receiver drilled and tapped for Remington 870 stocks, thus greatly expanding your customization options).

    -Bypasses 922r restrictions on imported firearms, the new receiver is technically the gun, just drop in your foreign bolt, barrel, gas system/recoil system/buffer, etc. and use all the 'evil' components you want.

    -Easily installed by anyone who can fully strip their firearm, does not require any special equipment.

    This would be considered a firearm and would be a serialized part, it would have to go through an FFL. Legally your shotgun would no longer be the make/model that it was, it would be the make model that was engraved on the new receiver.

    I am asking THR this because shotgun receivers are relatively simple and I don't think anyone has tried to make a modernized version of the common shotgun receivers. I believe there is a market for them in the tactical community. I have design drawings for the 870 version of the receiver that I will post shortly. I may one day raise capital and begin production of these receivers if my test marketing goes well.

    I'm not sure what it would be worth, but I'd be interested in looking at it for a 590 or 930. Wouldn't need to go around 922r because Mossberg is American.

    One feature I would suggest is a sort of ergonomic contour on the forend. Angle it slightly as it comes back, I find that to be more comfortable.

    Thanks for the feedback.

    This would not include a forend, only a receiver and magazine tube so the angle of the forend would be up to you. It would fit any standard forend for your model of shotgun.

    Would the receiver and magazine tube be one piece, or would the tube be brazed or threaded into the receiver?

    Just my .02,

    That is up in the air at the moment, as both are quite doable with the technology on hand. It would be easier to do them as one piece and most shotgun receivers that I've seen being sold separately include the magazine tube.

    Which would you prefer?

    Roughly same price as an AR-15 lower (pre-madness)

    Here is a side elevation of the receiver design:

    Ah, okay, that makes sense. One other thing: making it easy to install a side-saddle on the side of the receiver would be nice.

    What does installing one usually entail?
  10. Skribs

    Skribs Well-Known Member

    I don't do much of my own stuff, but I just mean make sure there's something there that a commonly manufactured side saddle could be attached, instead of just forgetting about them and requiring the user to figure out how to attach one.
  11. CmdrSlander

    CmdrSlander Well-Known Member

    With an integral top rail I could see a side saddle that attaches by slotting through the Picatinny rails like this AR15 brass catcher (but is mounted on the other side of the firearm).

    Side saddle scope mounts are a dime a dozen. A rail could be made in the same fashion. It would sell better because the aftermarket receiver would devalue the gun (IMO). Everyone knows what they are getting when they buy a gun with a stock receiver. Mossberg drills and taps their receivers. Rails are available on ebay for a reasonable cost for a Mossberg. To be frank I wouldn't buy an aftermarket receiver until they had been field tested for 30 years or so.

    I assume you do realize that a receiver would be considered a firearm by BATF.
    Sorry. It appears I can't read.

    From my OP:
  15. Fred Fuller

    Now IF l'l ol' me could get anything I wanted in a shotgun at this point, I'd like an 870 with a receiver that will accept standard 870 internals (3" is sufficient) and factory barrels, and have a user replaceable ejector and magazine tube. Aluminum or steel, makes not much nevermind because the lockup of bolt to barrel extension is steel on steel no matter what holds the parts in proper working relationship.

    That's pretty much it, for the receiver.

    I'm not much of a fan of cheese graters - excuse me, rails some call them - on genuine working guns. The ability to mount a ghost ring sight on the gun would be an advantage, and there's at least one model of such a sight that mounts on a rail. No need to extend it beyond the front of the receiver though, IMHO.

    That would mean having to provide magazine tubes threaded at the rear to fit the new receiver, since Remington mag tubes are soldered into the receiver. Having the option of swapping standard mag tube lengths (4-round and 6-round) plus being able to add extensions if needed would be an advantage IMHO. That would mean standard Remington mag tube threads on the muzzle end.

    hth, and good luck on the project - this could get really interesting!

    OBTW, the last stripped 870 receiver I bought (with mag tube in place) was $70 delivered. I'd pay twice that or more to get one that meets the basic outline above.

    Don't get it. The 870 receiver is fine. Your doing this why?
  17. CmdrSlander

    CmdrSlander Well-Known Member

    To offer reduced weight and superior hardpoints for optics and slings as well as user replaceable magazine tubes and the ability to mate accessories that are available for common shotguns (such the 870) to receivers that accept the action of less common guns (FN SLP). Look at Volquartsen and their custom 10/22 Receivers or all the companies that make AR15 upper receivers that are unique or superior in some way... it works well for them even though their is nothing "wrong" with the original firearm.

    I'll have a draft of the design you spec'd ready in about an hour.

    I love rails and am of the opinion that the flexibility they give the user makes any firearm better, but I can understand the opposition to rails as well. As a rule I don't like full on quad rail setups on my firearms, but a receiver and under barrel rail are musts for me, at least on a rifle. Shotguns, which have less use for vertical foregrips and bipods can get away with only a top rail.

    Here is Fred Fuller's stripped down variant:

    The issue with adding a rail on top of the receiver is it is taller than if you just have the rail included.
