Gun and gear reviews Mag extension or couplers

Just messing around with some mag extensions to speed up reloads. The small mag extension is ok but still a bit annoying to reload quickly. The coupler works well but I'm not the biggest fan of the flip reload. I designed "big black" so I can get a good grip around the shaft for easier back and forth in the mag well. This is just an initial prototype for sizing and attaching to mag.

I'll be honest I must have had a weird brain fart when I typed in the length. I'm going to print a shorter one with some shape modifications.

Aka the Ruger PC Carbine at home

Kinda what I was thinking in terms of the extended Glock mags.

u/FD4L Apr 30 '26

Big black needs to evolve into a trident/pitchfork so you can have 3 mags and shift the whole works sideways for reloads. 🤣

Hmmm...this is the kinda feedback I'm looking for . I'll see what I can do.

The two spare long boi mags would create a bipod for the rifle with the normal tripler

I want oneee

I've just started designing stuff. I'm nowhere near being able to distribute anything. It's just fun to make useful shit on the printer.

If the extended version was the same length as the grip i would be very interested

u/dgod40 Apr 30 '26

To get the gun to stand up properly? I'll make one tomorrow and see how it looks.

u/DougMacRay617 Apr 30 '26

No, i was thinking justt give it enough real estate for a positive purchase but without going all crazy long

I've got a version that's about that length and an mp5 profile one. Dm me if interested in more details

1

u/DougMacRay617 May 01 '26

So its like the same length as the one pictured but with a curve?

1

u/3DGunWorks Business Account May 01 '26

Yes the mp5 one is curved and about the same length. Then I have a second style that is closer to pistol grip length.

I like the trimags.

I think it's the fastest way to carry/swap 10 rd 10/22 mags in competition.

1

u/dgod40 Apr 30 '26

I'm literally 1 hour into a tri mag holder right now

2

u/Bubbafett33 Apr 30 '26

An hour? You should be able to reload in about 1-2 seconds when you get the hang of it....

There is a saying in these parts Slow is smooth, smooth is busch ice.

u/Planters_Donuts Apr 30 '26

What if you could make a * and get a mag on each point ? I have a 3 sided one but five sided would be interesting

u/No_Praline_1835 Apr 30 '26

Nice fake suppressor.

u/dgod40 Apr 30 '26

I'm all about the fakeys. Half the fun of firearms is larping.

I love the long boi, where can I find one? But personally I’m a coupler kinda guy since I hate being capped at 10 with a 22, I also have a few mags with extensions and it does make reloads a lot easier, but still not as fast as a coupled mag. I am a huge fan of the tandemkross mags as well, they function even better than the OEM Ruger 10rd mags and look sweet with the clear plastic.

u/swift_gilford Apr 30 '26

Personally the long version should be curved imo; Think more MP5, less UMP.

1

u/dgod40 Apr 30 '26

That's what I was thinking. Maybe not as bad as the tm22 but still a slight curve.

2

u/swift_gilford Apr 30 '26

Honestly if you just traced the BX-15 and/or the BX-25 profile you'd be good to go.

1

u/dgod40 Apr 30 '26

True. Probably makes the most sense.

u/GabRB26DETT Apr 30 '26

That's a BIG STICC

u/Zealousideal-Hat5814 May 01 '26

Mag couplers are way nicer

1

u/Girthquake2654 May 01 '26

Nice, just ran my double mag coupler for the first time today and loved it. Massively reduces the form factor of carrying mags for a plinking day. Gives it a really m1 carbine kind of look too

“I designed the “big black” so I can get a good grip around the shaft for easier back and forth”

If you ever decide to sell these I'll buy a bunch for competition use
