Got my GSG-16 today what a pile of

[tharkhold]

I measured the gun with a micrometer, modelled it in Fusion 360 and 3D printed it. I don’t mind making a couple more if you don’t mind paying for the filament. Shoot me a PM if you like.

I want to shoot the gun tomorrow and make sure that area above the charging handle doesn’t get super hot. I can’t see it getting hot enough to warp the PLA but we’ll see. I’ve got the day off and a 800 rounds of CCI Mini Mags lol

worse comes to worse, petg might work, then ABS if that's not good enough

Can you make me one of those top covers??

x3 please

The only reason I always start with PLA is cost and colours. If the prototype cheap Chinese PLA passes the torture/heat test tomorrow I've got ColorFabb PLA/PHA in matte black for my permanent one.

If PLA doesn't cut it I normally jump to ABS. I'm not a huge fan of PETG. I don't mind printing in an enclosure. But over the last month I've been experimenting with ASA to replace ABS as my go to engineering-grade plastic and I really love it... Unfortunately the only colour of ASA I currently have around is grey ApolloX I was using for a prototype at work. So we will see how hot this gun gets.

Id live one as well.
What kind of cost are you thinking?

[Wal-Mart Greeter]

Lemme dump a few hundred rounds through it tomorrow and see how hot it gets up there. My problem is ABS/ASA always comes out super shiny. I'd like to match the colour of the gun with a matte black material if at all possible. Once I figure out what material will work, and how many you guys want I will nail down cost and run them all off over the weekend. Keep you posted.

4.7lbs (with mag attached)

That's a pretty sweet number...4.7lbs whooowee

[phillyblt]

are the pic rails metal? they must be with that weight savings. with rail is 5.84lbs if I remember correct...at 4.7lbs is 1.14lbs off..wow

[Wal-Mart Greeter]

The rails are polymer. I don't know where GSG got that 5.84lbs spec... Maybe gravity is different in Germany. One of the online reviews lists it at 4.82lbs unloaded with magazine.

What do you think about unscrewing the rear sight assembly, chopping off the front sight ears, and installing metal HK drum sights on a full length rail? And upgrading all poly rails to metal ones?

sounds good but maybe a lil heavier
