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.

it doesn't look like it wants to stay folded on top, sadly. Makes me wish I had an active UKARA though

That's glorious. I always wanted a Sheriff SPAS-12. What's the receiver made from? The Sheriff SPAS always seemed a bit too... angular in the heat shield and stock though. the TM one really nailed it

Since the AA-12 is open-bolt (i think), could instead of a lock open device have something on the mag follower that blocks the trigger so it stops shooting with the bolt closed after the last shot? Sorry, I'm sure you've got loads of ideas... it's just Maruzen shotguns and the tinkering of were very much my thing

Interesting project... the M1100 gas system is pretty much bulletproof. A weak spot is is the fake bolt. I had a few snap at the attaching point to the blowback mechanism when putting high pressure gas through it, but it'd be straightforward to fab up a flat AA-12 shaped bolt out of steel or alu.

Western Arms? Prime? Sheriff? What is this? 2008? Reminds me of my old 1911 build before Hicapas dominated the market

There's an airsoft M79 on Thingiverse. https://www.thingiverse.com/thing:3334987 You could use that for inspiration, make a narrower version, hook up two triggers and put stacked barrels on the front. It even has an extractor. Make sure whatever stops the gun from opening too far is something like a steel insert so when you break it open enthusiastically it doesn't snap in half I also wouldn't worry about using plastic, my friend has an O/U I think it's a Beretta which just has a horrible black paint/coating finish instead of bluing Edit: oh the M79 has a top lever... I guess you'd have to make a post going through the action to rotate a locking latch thing beneath the barrels.

sent!

Yeah I just tried. there's just the hold for the bolt that attaches the stock to the body, sadly. I might try shooting right handed, my stance is better and it's less painful

good idea, but i think i'd have to replace the entire stock with lead... my gun weighs like half my friend's Beretta over/under. can't even remember the make/model of mine. it's got a wood stock but plastic pump grip at the front

I inherited the thing so I had to get a section 2 for it and my friends drag me clay shooting quite often. I'm right handed but shoot left handed so although my stance sucks I get better scores shooting left handed. I might try a bunch of 21 grams next time. Every other gun I tried, like my friend's over/under is heavy and has a soft recoil pad but mine weighs nothing and has a solid plastic cap on the stock. bleeh

Aha! yes they look familiar. They were quite expensive last time I looked and the only gun I can use destroys my shoulder so maybe the lighter cartridges would be better. I use whatever cartridges my friends use and apparently they like the heavier ones. My friend's wife uses a 20 gauge I believe which would be way better for me
