Default Military MK17 MOD0 VS. Civi SCAR-17S - (pic heavy)

MK17 MOD0 VS. SCAR-17S

Sorry for the poor quality of the pictures...

Here are the rifles well be looking at:



The first differences are the obvious ones. The MK17 has some extra markings and sticker. The selector markings are also different.



MK17




I expected the side rails to differ as Ive heard they do. On this MK17 they were plastic just like the 17S.

Digging in, I went straight for the obvious, the lower and FCG.
Obviously there is an auto sear in the MK17. The pictures don’t capture it, but the hammer and pin that retains the hammer are shaped slightly different.



Closer-
If you look in the rear of the lower, you'll see the 17s has a date stamp, the Mk17 doesn't.



Next was the ground down pin, front – left side of the magwell on the 17S. I’ve been told this is here for importation purposes.



Next, I dig into the BCG and this is where things get VERY interesting…

I did not have the time today, but the differences in the carrier are worth looking into.
Even at a glace, they look so different. Today we’ll point out the obvious, later measurements will be needed for sure. If you look close, the difference is already obvious…



Internals and the bolt appear same-same.



Cuts on the BCG, different. (look at some of the other differences not noted)



Rear for the carrier is also different. (again, look at all the differences not noted)



From the rear of the carrier.

On the MK17, there were some strange looking cuts. They were still bare metal.
These were angled slightly different than the cuts on the 17S. The Cuts on the 17S were not bare metal
they were anodized like the rest of the gun. I looked at another MK17 and it too had the same bare metal cuts.

Also note the “D” stamped into the 17S.



Another view

Gas blocks appear identical, same settings and all. I didn’t get the chance to pull the piston out
this time around. I spent too much time looking at the carrier.




All in all, I didn’t answer any questions. Having looked inside both side by side…
I’m just left with more questions… If anyone has specific question, or something specific you'd
like to see between the two, just let me know. Like I said. I’ll be getting more into the carrier
later when I have more time. Perhaps the end of next week…

Thanks for looking. I hope this helped answer a few questions about the differences
for some of you 17S owners out there.

wow it looks like they took the best of both AK and AR and put them in one rifle, referring to the gas and bolt design.

Very nice. Thanks for posting. The ground down pin in the mag well is weird. A few more detailed pictures of the FCG would be cool.

Yup. Anytime. Sometimes curiosity gets the best of me, I usually try and share.

Me too. I need a good day with the MK17 to do some measuring.
Range time wouldn't hurt either. It's been almost a year since I last shot it.

Nicely done! You should do some suppressor comparisons sometime. Just to turn us even more green.

I know, right? What a cheap piece of crap. Totally nothing at all like the Mk 17.
