SIG 716 G2 DMR Body Kit AEG
After doing the Surgeon CSR, i've been contacted for a SIG 716 G2 design.
SIG 716 G2 is based on the original 716i.
It was build to answer a CAN SOF requirement for a new platform.
"1 MOA at 300m suppressed".
It's available in 308, and 6.5CM
Base 716i : Direct Infrigement
716 G2 : Short Stroke Piston
The handguard is a bit like the MCX Spear LT.
Comparison between a 716 G2, and a MCX :

Airsoft'Wise, it's basically an AR10.
What AEG aftermarket will it use ?
- AEG Motor Grip
- AEG Stock Tube
- AR15 AEG Selector
- SR25/AR10 mags
- GB V2
- Nozzle 33/36mm MAXX
- M4 Hop Hup
- M4 AEG Outer Barrel 16/18"
(list may grow during the progress...)
(About the magazines, i think about 2 solutions :
1. Long nozzle 33/36mm, so you can use aftermarket sr25 mags.
2. Standard M4 nozzle, and an insert for the hop hup unit displacement, and custom made/printed PMAG mags.
We'll see...)
Before starting CAD, i compile some interesting pics from SIG manuals, and the Internet.




You can see some above but i have compiled more than 50 pictures.
Those pics will help a lot for the accuracy.
"Le Plat de Résistance" / "The Main Course" = CAD/ Design
First thing i do is the Lower, and then the Handguard since it will define the width of the whole Upper/Handguard combo.

Following with the Upper, and the Mag.
I'm also editing the Handguard all along the process.

Adding SIG logo, and doing more bits.

While the handguard was easy, the Upper is a bit harder.


Adding the Forward assist

Ejection port, dust cover guide and a lot of small bits...

SIG Markings, and mag release zone bits...

Full Upper


Working on the Lower/Upper Combo


Overall Render with Internals and magazine

Added Bronze color, and worked on details more and more...
Lot's of works behind the scene to match the real one, so all details are not necessarly obvious or visible.




The next big detail is the gazblock/gaztube/gas adjustment/rod
On the real 716G2 it's like that :

(courtesy of SIG manuals)
It's similar to an MCX, you adjust the gas using a palm valve with an opening thru the handguard

And here is mine




Small 10rnd pmag custom, and cocking handle



Prototype WIP :
18" outer barrel, V2 gearbox, sr25 mag and CTR stock


CAD was made with zero tolerance for a planned CNC machining of the bodykit once done.
3D printed prototype is full drop-in with zero sanding on any parts, wich is higgly satisfying.
Gazzblock group :



Some close-ups with a custom shorty mag.




D. Alexander, one of the JTF2 team member from the 2017 Mosul 3540m record, was equipped with 716G2 during multiple of his deployment.

Keymod version, first gen 716 DMR.
CTR stock, atlas bipod, NF scope, 16" barrel and SRD762QD silencer.

...
Thoses "wired" renders are specially made so you can see the complex geometry, and hope it will help you understand the amount of work needed for such accurate designs/works...
And of course since it's made for 3Dprinting, it's optimized for this usage, but can also be made in CNC, for a way bigger cost.
And for those who thinks they have the right to criticize something they are completely uncapable of doing, i am still waiting for you to do such things in the same timeframe as i do them ;)
