I don't think you'd be disappointed in the TM SPAS-12. Second hand takes the price sting off it and although it's plasticky, it's not 50-60 quid plasticky. It has the right heft and sizing to it.
I found it rough to pump using gloves as it has a big ol' spring behind it, and it's pretty slippery but the real one has a bigger ol' spring so whatevs :D
Might have been lucky, but I put the guts of a Celcius CTW into a Systema receiver to make a "cheap" M16A2 with 3rd burst. That thing was faaaaaar more reliable than either of my PTW's. It wasn't as snappy but it worked.
The DTW was shite though.
I had a TW5 briefly, and while I never really bought into any kind of Systema "magic" (I liked the slim grip and mag cutoff), the TW5 was actually crazy good. It shot for miles... the hop was awesome.
Also eww hot hatches.
I built two retro AR15 PTW's years ago... Couldn't stand the snide remarks in the lines for chrono at games so I quit playing. That new gearbox looks interesting though, especially if it drops into the existing lowers.
sadly it doesn't fit on my Maruzen 870, but those guns aren't proper scale afaik. Also, the screws on this mount are at different levels unlike an 870 which look to be about the same level as one another, albeit different sizes
I was after a "real steel" optic and was given this Qwik Point on a random shotgun mount (I'm guessing an Automatic 5?). It's interesting, albeit a bit rubbish.
It might look cool on my retro M16 AEG, or I might use it as a spotting scope for my camera
Not mine, but whatevs. Subtle mods to make an A1 into something slightly more retro.
My brother puts together retro AR's. He's nearly finished an M231 FPW
