I call this my low-crapa. Made mainly out of a worn out WE 1911 I was given to butcher for one of my springer pistol projects but seemed a waste of even a naff gbb seen as it was technically still functioning. Few old junk spares, CJ barrel/hop I got cheap and ended up not using from another project. The only bit I bought was the sights for £20 and the cj barrel £12 so for what's gone into it the results are actually not bad. With the lighter hammer/recoil springs, stock tm 4.3 capa slide it's a hell of a lot more efficient. You'll also notice the lack of recoil guide. I had to make a short plug & guide out the original 1911 one. In all quite pleased with it, just need to raid the kids Lego for rods for the sights.
