Colt Lower Receiver With ‘Shaved’ Magazine Well

I was sent a photo of an SP1 lower with a ‘shaved’ magazine well. The owner asked if I knew why the magazine well was like that. I had not seen one before and was curious to learn more. If you look below the rollmark and to the right of the rollmark, you can see the line showing how much material was ‘shaved’ off or removed.

Notice line below the rollmark and to the right of the rollmark providing a visual indicator of removal of magazine well material.

I posted an inquiry in my Facebook group and had some private message conversations which were interesting. I learned that when a mistake was made in the rollmark process or when adding the serial number (double print of a serial # for example), the factory would remove as much material as needed and then repeat the rollmark process or redo the serial number.

Anyway, I thought I would share this here so thatbothers can learn from it.

Colt’s Crew Served Weapons

If you are familiar with the Vietnam War, you probably know what PBR’s (Patrol Boat River) are. The PBR crews were some of the bravest personnel of the war in my opinion. Well, apparently Colt manufactured some of the bow twin .50 caliber machine gun turrets for the PBR’s.

Patrol Boat, River…more commonly known as PBR
Gunner’s Mate 3rd Class Earnest McGowan sits in the gun tub of the twin .50-caliber gun mount on a new Mark II river patrol boat (PBR) on January 13, 1968.  Many of these newer PBRs saw action during the Tet Offensive.  On the Mark II, the “.50s” are electronically fired and sit low on the deck.  (Naval History and Heritage Command image)

These turrets were also seen on Patrol Air Cushion Vehicles (PACV) used in the war.

Intact sets of these documents are rare. I never thought I would actually have a chance to own this document set so I’m pretty excited about getting ahold of it.

The folder opened. Factory images on the inside of the front cover on the left. Document pocket on the right.

I am not familiar with turret/weapon configuration shown below being used in active service.

Status of The Site For August, September and Early October

I thought I would mention a significant change that I have going on right now. My family has a new house (shown below) that will be completed at the end of September. We are in the process of getting our current home ready to be listed and on the market on 20 August. All of my Colt collection is being boxed and and moved to a location about an hour away from me to facilitate the home being shown.

The windows in the middle will be location of the new office

So, beginning about the 16th of August, I will not be able to generate any ‘original’ content until after my move is completed at the beginning/middle of October. I will try to keep the site active with ‘repost’ content or things I locate elsewhere.

As part of the change, I am eliminating some other interests that I have had in my life to free up time. When the move is done, I will have a new office in the home (windows in the middle of the photo) where all of my extra time that isn’t spent with family will be focused on ‘thecoltar15resource’ content as well as joint Colt related projects with some other sites. I am also going to be more active with the Colt Collectors Association.

So, please be patient during the next couple of months while I make this transition…don’t hesitate to message me.

Most importantly thank you for choosing to spend some of your valuable time each day stopping by here.
