Seeing as bullpup AKs are a little thin on the ground, I'm just going to have to build my own.

£30 at the local Airsoft car boot got me a somewhat unloved SRC RPK.

It looked awful, but a fresh battery coaxed it to cycle and once it was disassembled it turned out that apart from a lightly stripped piston the internals are barely used and in great condition.

A cheap (less than £20) AK rail was purchased from China.

Which has had one of the parts reversed and is going to be used upside down...

A quick rummage in the scrap bin at a local fabricators sourced a couple of bits of 2mm aluminium sheet, and then there was a lot of sitting and looking/thinking until my son suggested that I just 'Think like a Russian'. Simplicity wins the day, so out with the hammer...

You do realise that the Bullpup design means that the gun's action parts (and magazine) and located behind the trigger assembly, as per the British L85A1 rifle.  Yes, P90 does have top mounted magazine. It will be interesting to see how you reconfigure the gun.  I do like the attached RIS.

 
Trigger extension is next. It might need a bit of CAD, which in keeping with the low tech 'Russian' approach in this case stands for Cardboard Aided Design. ;)

 
Or I could just get a BTC Chimera and fit a slave trigger switch... so hours of twatting about for a mechanical set up that might not ever work properly or buy something that is easy, has umpteen fire control modes, pre cocking, ROF control, battery protection...Hmm.

 But only for a couple of models of GBB rifles as far as I could tell. Plus it looks like it fell out of the sci-fi ugly tree, and hit every feckin' branch on the way down... ;)

 
Can I get a V3 BTC Chimera anywhere, including the States? Not a chance. Until I check the classifieds on this here forum. Brand new, unused and posted for the sake of poking PayPal with a stick. Be rude not to.

The only problem is if I decide I want them on the rest of my guns. That could get a bit expensive.

 
I'm sitting here looking at the stock and trying to decide whether I like it or not... maybe something simpler.

 
The reach was too long and I didn't like the foreend.... So I threw it away and started again.

I've made a new trigger box that fits up inside the rail section which is cut away.

So the trigger sits much closer to the barrel and the grip can move back towards the magazine.

I Hacked the grip off my previous effort to mock things up.

Nailed it...

I don't know why I didn't think of this before. I've had the rail kicking around for a while, but this morning, for some reason I saw it in a different light. So I chopped it up.

Im not going to be short of rail space.

 
I've decided it's an AK7, cos it's like an AK74 but shorter...

 
It's going to have a Chimera ECU, so semi with pre cocking, three round burst with a trigger tap on auto and full rock and roll if you keep the trigger down.

 
I've finished cutting, filing, drilling and tapping...

Bits, and pretty much all the tools used to make them.

Assembled.

Enough space for 2200mah 11.1v lipo bricks, and the spring latch makes them easy to access.

Paint next.
