Thread: Stirling Model P20 Bullpup conversion

This is my Stirling Model P20 conversion, using one of the many Steyr BB guns available on TradeMe. I paid $19 for this broken one, then gutted it using my Dremel knock-off.




It doesn't need too much modifying to make it fit.



This one uses the Stirling's slip on silencer and a bipod foregrip, which replace the fake ones from the BB gun.



A couple of hours work with the dremel for both halves of the clam-shell. If I do any more I will be much quicker now I've worked out where everything fits.





This is a piece of stainless steel from an ATM cash canister guide rail to keep the trigger linkages straight.



The trigger linkages are two welding rods attached from the BB trigger (a spring goes behind it) to the Stirling trigger.



It's not the most practical piece of kit but I reckon it looks a bit cooler than the original. I may possibly modify the BB mag so the Stirling one fits inside it but then I would have to register it as an E-cat weapon.



This measures 31 inches with the silencer, 30.5 inches without.
