I know the knights ones are rare and stupid expensive, but are there any us made set ups I can get? I know there is a Canadian one but I don’t know if they import to the USA.

I’m about to send a 870 magnum receiver off to get the Mag tube cut down to MCS length. I also want to get sling swivel installed on the top back end of the receiver but I don’t know if it’s threaded in. Soldered in or if there’s type of nut inside….
So to hijack your thread , does anybody have a Remington MCS with some close up pics? |

Anyone have a video of someone trying to breech a door, from the lock side, with this monster?
I prefer the stock/grip to be as thin as possible near the receiver to use my thumb once you have it angled in and down. |

If people want to play with breeching rounds, a cheap option is to take a single shot, shotgun and cut down the barrel to 18” and the stock to where you still have 26” OAL ( to avoid NFA stamps). Because the receiver is shorter, you can get it shorter than a pump.
Note: most breeches are going to take more than one shot. |

Quoted: Nice! His website I believe it is a one man shop. I have messaged the owner on FB for general questions about the mount and the capabilities. The good thing is the mount can be utilized for both the 870 and 500/590. However, the 500/590 needs an extra work for security and if i remember correctly it was the installation of helicoils into Mossberg receiver. The 870 just drill and tap. |

If you are wanting to go the whipit route with pistol grips, i'd recommend getting a set of the old TacStar type grips. The are based off the old Thompson 1928 grips front and back. The good thing about the front grip is that it forces you to not let your left hand get too far forward and be subect to the mussle blast or worse. And they push the recoil down into the palm of the hand, not driving it into the web. This does make recoil hurt a lot less.

I think I'll end up with the pirate gun (only a pistol grip) but I'm still messing about. Hogue will be considered next. |

it's an annoying and expensive proposition. I tried. The 870 needs to be SBS. Then you need to either get the standard lower tube/barrel, which works out to be ~12.5" barrel at the end of the clamp ring, or source an MCS (I think) military kit for the shorter tube and barrel. Forend bars need to be cut short and rewelded. then you need a clamp, either one of the knights if you can find it or cheap clone copy, lots exist. You need the right barrel/handguard for whatever you decide. If you can do this work, great, but if you farm it out you need the original length parts and the cost of mods worked out to be $800+ last I looked from reputable people.
I believe you wouldn't need to stamp the 870 SO LONG AS the gun you have it attached to is a "pistol" and has a brace, cause then your 870 (so long as it started out a firearm and not a shotgun) would meet the same general requirements as a tacwave, but I'm not a lawyer. In the end, I spent $400 cutting a few inches off a $200 18" shotgun to get one that's only a hair shorter than a shockwave is. I never shoot it and it now wears a folding stock for shits and giggles. WIth the 12.5" barrel and action, you're at about 24" OAL. Which is just a hair shorter than the 26.5" shockwaves. And like 8" longer than a damn rattler is folded. I'm not saying it shouldn't be done, but it's pretty low on the list of range toys for me. I mostly stamped the 870 cause it was my first gun and I'll never sell it anyway, so why not? I did SBS instead of AOW so I can throw on a PG, birdhead, folding, or full stock and be 'legal' in my state. It's silly but I think that's OK. |

Semi autos are fine and I'd say failure rates with a clean semi shotgun shooting high brass loads is way lower than the number of short strokes on a pump under high stress.

I used to make a similar design called The Doorknocker: Firearm Accessory Mount, a bar of 7075 T6 aluminum milled down to the M203 spec with the underside milled out to fit the 870 receiver top using a custom ground ball end mill. Used to sell them for $135 plus $5.95 Priority Mail.
The Moss 500/590 could fit, but the mount blocked the safety lever, I was worried about getting sued because some numbskull shot somebody running around with the breacher off safe at all times. I always wanted to try to mount the old Mossberg 9200 Jungle Gun semi-auto using the Doorknocker. I sold the tooling and "tech data package" to Jonathan in FL but he went bankrupt. I'm not sure if the design is owned by any bank or creditor at this point, over 18 years later. |

I want to agree with you, but theory and finding someone that used it in the dirt and can say yeah, this worked great but no one wanted to pay for them, and the maintenance was too much. I truly want a semiauto breach-only tool. Past my time, but... I still want it. I didn't see too many short strokes, but I grew up in the time that a pump gun was also what people were using to put food on the table, deter predators and hunt people with. Now that it is deprecated and relegated to minor roles, I can kinda see it. I should have been more worried about overstroking and hamburgering my girlfriend, but I could never see my way to putting a DEA duckbill on any of mine at the time. (And still doesn't explain why I can't build a V3 cheaper than buying one lol) I saw a real masterkey a long time ago. I just didn't have the upper body to where it made sense to me. |

Hey guys! Our guns are plug and play clones and are $1850. The first run is SBS only (for the reasons already stated above) but we will have a very limited number of AOW's for brace pistol/firearm use as well. Also, when making a AOW, the base gun can never have had a stock attached so in our case we used Tac14's while all of the SBS's used standard stocked 870's.
Recoil is a little less than what you'd expect just because of the extra weight; I mean you are shooting two guns. The video below is firing reloaded 2 3/4" #7 1 1/8 oz. but high brass loads aren't terrible. You can also use a better stock/recoil pad too if you're not trying to clone something.
