Project Peregrine

Recommended Posts

After the disappointment of the VFC MP7 AEG I figured I'd make my own. I picked up a second hand ICS split gearbox for cheap and a bunch of Ares 9mm magazines and have modelled them up in Fusion 360 with help from @Hangtight as I am using my own version of his custom gearbox concept. For the trigger I'm using a BTC Chimera with custom made microswitch modules for the trigger, selector and cut off lever.

 

Which brings us up to date on the work done so far. I need to draw up an AEG outer barrel and a pair of side plate to be laser cut for the lower gearbox and I can start work on the 3d printed parts. These will include a central trunnion that all other parts will be mounted from, a monolithic upper receiver, an Uzi style removable forend containing the battery and MOSFET and a single piece lower receiver/pistol grip/magwell. The lower gearbox will also have 3d printed infills to hold the side plates together. 

 

The final product should be around 400mm long but with its full sized gearbox and an r hopped 200mm inner barrel it should still be capable of 50-60m accurately.

I love this idea! I always wondered why a RIF *had* to be a copy of a real gun amd how you could lay things out if starting from a blank slate.

 

I will be following this 😁

Thanks. it's a lot of the busy work currently, modelling up the existing parts and getting the layout finalised to be able to start drawing up the printed parts. So far it's looking promising though, there's a lot more space for your thumb than it seemed in my rough initial sketches

A rough mock-up of the layout.

Is there no option to angle the grip? Doesnt look all that comfy

 

I'm looking at options for Glock style mags. I was going to go for the Classic Army X9 mags but they're out of stock everywhere at the moment. The Ares m45 mags are looking like a better option currently. This would be as an alternative lower receiver later down the line

If your 3d printing the reciever you could angle the existing mag back and have a feed tube to line up with the hop?

It may come to that. These are only 45 round mags so I was trying to get some higher capacity mid caps to make it more skirmishable. The final grip form is going to be closer to an MP9 to make it more ergonomic than this very rough sketch

A quick exploded view. A couple of major components missing from this are the trigger module, lower gearbox and the trunnion to mount the outer barrel in the upper receiver
