Okay, so if you’re expecting to hit me with the “it won’t fit!” I’m well aware…so now I’m making my own and figured I’d share the shenanigans of it here.
This was a bit of an after thought, so it won’t be as thorough as the random undertakings of others projects.
It started out because someone asked me about the 22LR build I did using the CMMG drop-in kit. Then they mentioned they wished though could use their BAD Lever.
I recently moved and broke my printer while packing it up to do so, but this gave me the kick in the ass I needed to get it repaired and start working on a new project. Anyhoo…
The first thing was figuring out how far forward I’d need the initial ‘arm’ to be in order to have the lever sitting in the trigger guard. I’m slightly ashamed to admit it, but I was half tempted on leaving this as is and calling it a day since it teeeechnically was sitting on the bolt catch and in the trigger guard. However I know I couldn’t call it quits just because it somewhat sorta worked and could be functional.

So on came the shenanigans of adjusting it until it fit properly. I was honestly half expecting to wing it and get lucky, but as you can tell from the multiple prints, that wasn’t the case. I also had one fail, which it the stubby little one, so I had to flip the model to print it differently.
I’m sure the keen eyed might have noticed the initial picture was on the right side, so the lever would work for lefties, which I am not…so I figured I’d also mirror the design and get it going for the right handed shooters.

Needless to say, these receivers are such an oddball shape man. That said, I’m pretty sure I’ve got something that’ll work or am at least really close to it.
I’ve got ample clearance for the left side magazine release and the lever doesn’t hit the receiver when the bolt catch is activated. Being honest though, I might tweak it a tad bit. It sits a wee bit close for my liking, I also want to somewhat account for the tolerances of machining once I eventually send this out to get made out of something a little sturdier than plastic.



I do think there’s enough clearance in the trigger area though. Mind you I’m sure I could adjust the design so that the arm sat a little further forward in order to account for people wearing gloves and stuff. I’m just not sure if by doing that and adding another angle will just cause things to bind up and not actually function as intended.
