Yeah, I ran a buffer tube with the Defiance stock on mine for a while. Don’t know why but it was smaller diameter than a normal buffer tube and no way to fit a lipo in it so it stayed wired in the grip.
Then of course you’ve got the problem of the stock itself which is very sexy imo, that’s too small for any other blaster that’s running a normal tube.
I didn’t really like the ergos and cheek weld much and it felt kind of wrong so I went back to the KV skeleton stock. I think they look more purposeful and mean with them on and very comfy to shoulder.
If there was a kit available it’d be hugely popular.
Sadly, there ain’t… yet! Fingers crossed.
But I agree… as iconic as the M41A pulse rifles from “Aliens” are, they’re horribly awkward to handle. From the looks of the Romulus props if it was available in gel form it’d be a nicer bit of kit to use.
