Pkekyo-Nor Posted February 27, 2010 Report Share Posted February 27, 2010 I'm currently in the planning stages for building two M249 pintle mounts, and will base them off this design: Planned features: - Steel construction - Sans ammo box rack - Optimized for CA M249s I would love it if anyone have stuff such as measurements or detailed reference photos, as I want this project to turn out as good as possible. I only have the three photos posted above to work from, but I believe I have a decent understanding on how this stuff is set up to work, despite not being able to figure out how one would use the rear pin to secure the gun. I started out with a photo of my M249 and did a quick sketch in photoshop: Red: Pintle Green: Cradle Blue: holes for screws/bolts and whatnot Then I turned onto doing a cardboard mockup, in an attempt to quantify how big a sheet of steel I'll have to get, and as an attempt to find and work out any issues before starting actual production. Right side: Bottom: Left side: - And that's about as far as I've gotten as of now, I'll make a mockup of the pintle as well during the night or sometime in the morning. I'll keep the thread updated.

Pkekyo-Nor Posted February 28, 2010 Author Report Share Posted February 28, 2010 Yeah, that's the site I snagged my photos off. It doesn't give any insight in detail though, so I'd very much like as much proper info and photos as possible. Thanks though /EDIT: Finished the pintle mockup. It sure ain't pretty, but atleast it's proof of concept, right? /EDIT2: I've been concerned about the rear of the mount, and the possibility of it dislocating itself from the MG, so I tried this: In the production version, I'd do this with metal rings in the cradle assembly, and possibly a piece of chain, or maybe just a heavier weight of shock cord.

BigEd Posted February 28, 2010 Report Share Posted February 28, 2010 The rear half of the cradle assemble is normally attached to the front locking pin on the trigger guard assembly. This is where the a T&E is attached when the gun is mouted on M2 tripod with a gooseneck pintle. Having a single fixed point on the front trunion will be very loose. I would extended the lower tray of the cradle assembly to attach it to the hand guard locking pin. (just like the real one). But since it is an 249 airsoft magazine which is usually attached to the gun. You can stick the box mag into a ammo can and extend the feed spring to reach the gun. Another option would be attaching the rear half of the cradle to the bottom rail. ///ed/// Link to post Share on other sites
Pkekyo-Nor Posted February 28, 2010 Author Report Share Posted February 28, 2010 Yeah, but as an airsoft gun extending the mount further back really isn't a very good option, as detached mags... Well, they won't work well. I have a coil of rather heavy weight shock cord laying around here, and think it should serve us well enough just to keep the rear of the cradle in place, it's not as the rear will be loadbearing. Worst case scenario and it doesn't work, one could always just chop off the rear portion of the cradle entirely and have a single contact point up front. Figured we'll be needing two sheets of 2-3mm thick 50cm * 50cm steel for this build, off to see if I can find a supplier in the morning. Thanks for the info on the RS mount BigEd! It's greatly appreciated. Link to post Share on other sites
Pkekyo-Nor Posted March 15, 2010 Author Report Share Posted March 15, 2010 Some progress... Albeit small. The steel cost me 300NOK/34GBP/51USD, but it seems I bought twice as much as needed. So there's room for cock-ups Or if I don't sod anything up, I might just make another two mounts and flog them to the highest bidder... :> Link to post Share on other sites
Roskov Posted March 16, 2010 Report Share Posted March 16, 2010 Well im sure there's a car nearby waiting to be mounted by some m249, so selling those mounts shouldn't be hard Link to post Share on other sites

Pkekyo-Nor Posted March 26, 2010 Author Report Share Posted March 26, 2010 Just waiting for the lad with the plasma cutter to find some spare time Got some days off coming up, hoping to get it done sometime next week! Link to post Share on other sites
Noart Posted March 29, 2010 Report Share Posted March 29, 2010 Love it! I like the thing that you will keep the "normal" mags on the gun, incase you want to disembark you don't have to play around with the box. Where's the favorite thread button? Link to post Share on other sites
