M118, brand new. First time firing it today.What ammo were you shooting and when was the last time you cleaned your gun?
M118, brand new. First time firing it today.
I’m wondering if it’s just being a new build and the oils/lube.A newly cleaned rifle can create lots of smoke. The cleaning solutions can burn and create lots of smoke which is most likely what we are seeing.
I couldn't tell from the video how the rifle was running but it seems ok.
Some types of ammo/powder can create excess smoke as well. Not enough info to diagnose it further.
If there was good reliable function then just shoot it and it should clear up.
I would venture to say it's 99% the new gun/gun cleaning/whatever crap they put on new guns burning off.I’m wondering if it’s just being a new build and the oils/lube.
My tikka ctr seemed to throw a bit of gas out the end too, it was also new/unfired until today.

Not sure if temp has anything to do with it but it was about 38 degrees
I’ve got the arms spec silent spring in itI would attempt to get the operating system to stay shut longer as well - that really cuts down on gas.
Think heavy buffer as a start.
There are people that think this would matter, but I'm not one of them.I’m running the aero adjustable gas block, wonder if I went to one like the superlative arms with bleed off, if it’d help a little.
I’ll fire some more rounds down it soon to see if it’s the same. Only ran about 12 rounds through it today to zero/ verify function.
I adjusted the gas block 1 click at a time until it locked back on last round, then moved it 1 more click.
I didn’t really notice it too bad while shooting, but in the video, seems to be rather gassy.
This is my first can, so just making sure all is normal.
Thanks for that. And you’re correct on the ejection, the first few were dead on 3’, and I had a few towards the end shift 1.5-2’ a little.Normal - First one green circle highlights the vast majority of gas coming out of your BCG vent holes.

Normal - Orange circle highlights gas coming out of your upper receiver clover leaf where the gas tube goes through. The gas key/gas tube doesn't create an air tight seal.

Normal - Red circle, you'll see this especially with new builds and the carbon/fouling hasn't had a chance to create a tighter seal around your gas block and gas block journal on your barrel. This gas volume slowly reduces the more rounds that get fired. It could take anywhere from 50-200rds depending on how "dirty" your ammo is. During this time, remember to readjust gas block settings as you'll see your ejection pattern start shifting forward even when the rifle is cold. If you run a bleed off gas block, the red circle will have more gas shooting out from this area.

Ejection pattern - This could be camera angle, however, it appears to me your ejection pattern is starting to shift forward closer to 2 o'clock as everything starts to seal up. Reduce AGB by a click or 2.

Final - Yellow circle - note how initial exhaust of gas is not at charging handle and into your eye. Most gas escaping out the ejection port. Residual gas coming through the charging handle as the BCG travels farther rearward also normal.
