The build is complete

[u/Ravens_beak224]

1970s Remington 870 Wingmaster, the last two pictures are the only ones I have of it in its original configuration with the 30 inch vent rib barrel I've been slowly getting parts together since I bought the gun. I was going for a 70s FBI/police shotgun, but in my mind every shotgun needs a bayonet so I had to have one even though law enforcement don't run bayonets.

Build list

1. Professionally chopped blu'd 870 Wingmaster barrel without a vent rib

2. Ground down and drilled steel round stock with nut and bolt to accommodate the bayonet

3. Blu'd 870 OEM +2 magazine tube extension (the original one I had was parkerized and clashed with the bluing of the gun)

4. M1 carbine bayonet I believe its official designation is M4 not to be confused with the rifle or shotgun of the same name.

5. S&J bayonet ½ mount

6. Grovtec barrel clamp w/picatinny rail, QD cup, and sling swivel. I'm not a big fan of the pic rail and will probably swap it out with a nut at some point in the near future but its what the bolt screws into so I dont really have a choice, I also decided to exclude the QD cup for the same reason.

7. S&J magazine spring and follower kit, minus the follower I love the smoothness of their spring but I didn't want the high vis follower just a personal aesthetic choice although I do know them to be incredible followers.

And finally to top it all off a custom made leather bandolier/sling. This one was also aesthetic I wanted a leather sling to complement the wood and the dark tones with the lacquer finish but I also wanted it to be able to hold shells so I had something custom made and I'm glad I did because it looks like it belongs on the gun in my opinion, the width makes it very comfortable even loaded down with shells. All said and done I think it was money well wasted.

What length was the barrel shortened to? I’m thinking of doing a build like this and want the mag extension relatively flush with where the barrel is cut

18.5 inches it does stick out just a hair past the +2 tube though.
