Waaay out west.
Just a neat video I thought I'd share. I shot a couple hundred rounds through my 12" VZ doing various drills and noticed she was getting a little toasty. So I put on some gloves and put another half dozen mags through her, just for shizzles.:D That area gets sprayed with lots of G96 lubricant/cleaner so I guess it was just burning off the excess...

(P.S. for those that notice, during the mag change with the short mag I had some problems getting it into the mag well so I hit the ambi mag release to help it. It looks like I put my finger inside the trigger guard but I didn't, just a weird camera angle...)

How did the hand gard take the heat any melting?

No, it wasn't nearly hot enough for that. Just hot enough to give me a good burn if I wasn't wearing gloves.

Half a dozen mags (Canadian)= 30 rnds = 1 U.S. mag...sad isn't it.
Yes it is. What bothers me the most is trying to run drills with 5 round mags. VTAC 1-5 is impossible, VTAC Tripple threat as well.
2-2-2 drill is about the only multiple round drill you can run without getting into an inordinate amount of mag changes.
 
I stopped spraying mine with wd40 because I would smell like it for hours after shooting haha.



Nice video.
 
Wha? I clean the piston and block lube them, give a quick wipe, and reassemble.

Yup. Lubricant can catch fire or turn into a hard-to-remove tar that will also cause the piston to seize inside the block. Although the smoke may look cool it is not normal and may be causing damage. That whole area should be as dry as a whistle. Also, resist the urge to overclean piston rod heads. Using steel wool and abrasives may reduce the seal necessary for the gas piston to work properly. When I was in the Army most FNC1s piston rods were scrubbed till they shone. Unfortunately the gas system was skewed and we had to dial the pressure up. This is also where I learned to keep gas piston rod area bone dry. Absolutely no lubricants past the start of the barrel area.

Thanks for the explanation. I think most of the smoke is coming from the barrel under the piston. Like I said I wipe the piston down before I reinstall it. The barrel under the piston gets sprayed liberally with G96 and wiped out but it tends to pool in the crevices under the handguard.

Ah!
You were in the Army when I was. You speak of the FN-C1. That was my first rifle in Basic. Its nice to know that there is other old guys who used to where Olive Drab. Lol! Pro Patria brother. From 1RCR.
I remember how nasty those rifles gas systems were. I used to buff the crap out of the piston and carrier. We were warned if it wasn't perfect, we would be charged. Ah, the good old days.
