My RRA 16" Predator Pursuit is leaking gas from where the gas tube enters gas block, also gas exiting from rolled pin. RRA 20" Coyote doesn't have this indication. Both purchased last October. Do I have a situation that should be corrected??? Thanks!!

The tube and gas block both have to have tolerances to allow them to fit together.  You probably have a littl eblow-by gas leakage around the barrel at the gas block as well.  Unless excessive, it's normal.  It'll form a scab of sorts after a bit and that will pretty much be the end of it inless you take th etub eout or th eblovk off, in which case it may start again until it scabs again.
If it is excessive, we can certainly take a look and repair iof/as necessary.

Thanks for the reply Steve. Not sure how to measure "excessive"  - I guess it singes the shoot next to me (LOL!) or it refuses to cycle (I'm shooting XM193, and my reloads are 2700-2800 fps.) - I'll continue as is.

if it's peppering  the shooter next to you, you're getting more than carbon.
Better talk to Customer Service/Technical and get the upper half in here so we can take it out and see what's happening.
866-980-7625.  We'll ship it in and back on our dime.

My apologies Steve - I was just trying to be funny on how to measure "excessive" - my RRA is NOT peppering anyone, just some leakage that I had not noticed before but is evident because of the SS barrel. As stated, I'm Rocking along! Thanks! The only weird part is gas coming from the roll pin - but as you stated, it should heal or scab over with more use.

Cool.
It's coming along the exterior of the gas tube and seeking the path of least resistance out....around the pin and out the tube port in the block.  Sounds like some tolerance issues with the tube (small side of things) and the channel for the tube in the block (high side?).
