New AR10 Smoking after shooting

[steveber]

Good Day all
Not sure if this is the right spot for this and if its not forgive me please.

I just bought a new Sig 716 AR10 and took it to the range the other day. After putting 240 rounds threw it at the end of shooting it for the whole day at the very end I put like 60-90 rounds threw it in 5 or 10 minutes (I don't recall the exact numbers). I was excited for finally getting the scope set up and was having a fun day shooting the steal and hitting it every shot I took at 300 plus meters. After shooting smoke was coming from the piston and barrel area. It lasted only few seconds but the barrel was very hot.

Was this bad for the gun?

Ammo used was the Hirtenberger 7.62x51 Nato.

Thanks

no. most likely oil burning off.

 

[Redblack]

Nope, just oil burning off

 

[JayCarver]

Just means your using it.

Its a piston. The gas block or barrel around that area may have had something that likely burned off.

How was your bcg after 240 rounds of ammo?

Hey look - a total "AR Newbie"! Don't worry OP, we were all where you are at one point. Welcome to the exciting and fun world of big-bore ARs!

People asked about your Bolt Carrier Group (BCG) because it should have stayed relatively cool and clean thanks to the piston area collecting all of the heat and fouling (residue) from firing.

308 is big bore now?... Only to an AR Guy... Lol

Can't wait to show my friends my big bore hunting rifle! That 303 brit is a beast! Lol


OP, did you strip and clean the internals when you bought it? Or might that just be the grease it was shipped in burning off?

 

[Stray03]

Im surprised smoking is the only issue your gun has after throwing it around all day at the range.

 

[enefgee]

Wait until you get it hot to the touch at the hand guards - great on a cold morning! As noted, perfectly normal - have fun!

Thank you BARTOK5 for going easy on me I'm sorry I am new to this. Im big into shotgun (and shoot it competitively) so if you want to talk big bore I have a 10 gauge I can show you LOL. It was the piston area that smoked and the bolt area I never really felt but not remember it to be that warm.

As for the others the only cleaning I did was pull the bolt out and lube it up with oil and run a bore snake threw it 3 times and just shot it.
I did the same thing when I bought that special edition Colt Canada C7.

You ruined the temper of the metal. You need to send it to me for disposal.
