Hey guys! Building my first grendel, and first stainless barrel build also. I found a 12.5 BA Hanson bead blasted stainless barrel for a great deal so I pulled the trigger. The place I bought it from even offered to cerakote it for 40 bucks and I have no idea why I didn't go ahead and do it.
This pistol will be mostly a night coyote and hog rig and I'm worried about rust especially without being able to wipe it down under the handguard. Should I just go ahead and duracoat it when I get the chance or are their easier and cheaper options for rust protection

Take the handguard off and clean the barrel, when finished but the handguard back on.
Simple, cheap.

I'm installing a Larue Mlok handguard on this build and although it will be my first time with this handguard, it appears it would be anything but simple for me. Lol

Place the Keeper, Handguard Nut and Barrel Nut on to the Upper in that order. Apply Aeroshell 33 or equivalent on to the uppers threads and torque to minimum spec then go a bit further if needed to align the hole for the gas tube. Slide the Spacer over the barrel and then install your gas block and tube. That last bit is the one thing the LaRue instructions get wrong IMO. Trying to install the gas after the guard is secured can be quite difficult.
The BA micro gas blocks fit through the back of the LaRue guards just fine, be sure the gas tube roll pin is fully seated and the pin for the block is centered, that one is overly long and will block the guard if not centered or shortened.
I apply a bit of grease to the guard threads then assemble and tighten with a strap wrench. Apply some blue loc-tite to the lock screws and install and you are done.

Where did you get your barrel? I had been trying to find one since early Dec. but all out of stock everywhere I looked.

As already stated, just remove the handguard and clean it and reinstall. It really isn't difficult.
If you wanted it painted, that cerakote job for $40 was a fair deal. If you rattle can DuraCoat, buy the paint and the recommended TruStrip cleaner/degreaser kit from Lauer Custom Weaponry, that kit will cost near $50. If you have a good sprayer or airbrush and propellant already you might DuraCoat it a little cheaper.
I haven't used DuraCoat on stainless so don't know how well it works. For application questions give Lauer a call and they'll be happy to answer any questions you might have.

The stainless barrel can rust. I had a stainless Kimber 1911 once I let rust bad under the frame grips because I thought it wouldn't.

Yea, I definitely should have jumped on the cerakote.
I ended up cheaping out and going with some duplicolor high heat engine paint. I'd read mixed reviews about it and I dont know how it would hold up to solvents but I was very impressed with the handling it that got done during the install.
