870 mk1

[colt thompson]

I have a lead on an 870 with US property marks and the blade front site/bayonet lug. The serial number is s087652v. What's the current market value?
Thanks

Any photos available??

According to Canfield's "U.S. Military Combat Shotguns" book, (Collector Notes, page 193), your serial number appears to be within the USMC Model 870 Mark I serial number range (S081347V - S127,697V, with most known specimens falling into the S117000V - S129000V range).

Canfield also advises that some USMC 870 MKI's had "US Property" or similar markings "rather crudely hand-etched, usually on the left side of the receiver" - but, "not all of the 870 MKI shotguns had such post factory markings applied".

From my research, genuine 870 MKI's are still in limited USMC active service (Standard "B" weapons). Very, very few complete shotguns have legitimately made their way into civilian hands. On the other hand, the USMC Bayonet Adaptor Sleeve (with Rifle Sight Ramp/Base) do come available from time to time. Over the last 10 years, I've only seen three (3) legitimate USMC Adaptor Sleeves on the open market.

Stocks/Forends more frequently show up for sale. However, stocks may have a locally applied (USMC Base) "Rack Number", either hand etched or stencilled on, but without provenance, almost impossible to tell if from a USMC, USAF, USN, or early police 870 Riot shotguns - all used similar type plain walnut wood.

It would help if you could post up some photos, we would better be able make informed observations...

Be very careful. There is a guy on Long Island who "makes" US marked 870's

To reinforce what "scosgt" is cautioning, have a look at the attached 2013 auction listing where a fake USMC 870 sold for nearly $9,800.00!

And, I've been corresponding with a novice combat shotgun collector who recently got burned for $1,500.00 on a purported "870 Trench Gun" - the only part having any value being the Early/1st Type, One-Piece, Bayonet Adaptor Sleeve. Came with homemade heat shield. He "bought the story" that came with the pictures. See below.

On the outside, the Adaptor Sleeve looks pretty good, but are there close-up photos of the Sight Base?

If you are able to remove the Adaptor Sleeve and look inside near the front of it, there should not be a hole that would indicate it previously had a Bead Sight installed. Legitimate USMC 870 MKI Adaptor Sleeves WILL NOT have a Bead Sight hole covered over by the [soldered on] Rifle Sight Ramp Base.

Remington offered Bead Sighted Adaptor Sleeve kits to the USAF, USN, and police - these are identical to the USMC Sleeves, except they are Bead Sight Only - No Rifle Sight Ramp.

Can you provide profile photos of the complete shotgun, including close-ups of the Rear Sight and markings around it, Bolt, Trigger Guard, Stock, Rear Swivel Assembly and Butt Plate?

Have you been able to measure the Barrel for 21"?

I don't particularly like the US PROPERTY stamp...a little fishy looking to me.

The barrel is MOD so there is not going to be a hole if it was cut down.

Just to clarify, I was talking about if there is a hole for a Bead Sight in the Adaptor Sleeve (under the Ramp Base) - not the Barrel.

The Mark I guns were made by Remington under a 1969 USMC contract and there several features specific to the guns. Genuine Mark I shotguns are extremely rare "on the loose" but Model 870 shotguns fitted with bayonet adapters are fairly common. Some were fitted with the adapters under government auspieces. Most weren't.

I used them on active duty. Have never seen the real deal outside a USMC Armory. I do have a USMC adapter, barrel and extension tube mounted on a 870 Express. I was a Combat Shotgun Instructor for the USMC Security Force Bn Pac. I found the adapter, barrel, and extension at a LA gunshow at the Fairgrounds there. The seller was a retired USMC Armorer, where he got it I have no idea. I was teaching at NS Long Beach and the Navy was using Mossberg 500's. I had my Express set up like a MK I. I used it to teach the Combat Shotgun Course. Still have it and will keep it, not many folks can say that they have a gun they used on active duty.

Well, I bought the gun. I'll post detailed photos when I receive it

Sell it to me... I'm going insane looking for parts. Anyone have any spare parts kicking around?
