Machining melonite/nitride-coated barrels - who?
I'm building a rifle and plan on using a 16 inch VooDoo Innovations melonite-coated barrel. I haven't fully decided between their ultra-light or Govt profile barrels, but my understanding is that they aren't dimpled and they don't offer a preinstalled low-profile gas block on either. My goal is to get the gas block pinned, but it doesn't appear that ADCO or Rainier will dimple and pin a gas block on a melonite-coated barrel. Questions via their websites yield no replies (yet). AR15barrels.com likewise.
- anybody know where I could send a melonite-coated barrel for gas block pinning? (there's nobody local I'd trust to do it)
- any thoughts or experiences on pinning a low-profile gas block on a .625 inch boss? I've seen lots of lore - everything from "not thick enough" to "disturbs barrel harmonics".
I'm aware of the minor controversy surrounding pinning a gas block with some people viewing it as unnecessary, but it's my preference.
TIA

I get all my gas blocks pinned/dimpled. Just a personal preference.
Last I checked, Rainier was trying out some new drill bits to dimple and pin melonite coated barrels. I don't think they'll offer it as a service until they can with 100% confidence get the job done.

I appreciate the update. I realize it will probably be harder on tools and fully expect it will cost more on a nitrided barrel.

However, thanks for reminding me through this thread. They asked if I wanted to be a guinea pig for their dimple/pin test, so I'll bring in an Aero barrel. We'll see how it goes.

You can do it yourself with a hand drill and the jigs from BRD Engineering. Rainier sells some of his jigs, I've bought from them and direct from him as well.

On a side note, the only .625 LW barrels I have are pinned with a FSB. RA doesn't have a jig for LW barrels, so they can't pin them.

Ahhh, bit of a far drive. I may have to take you up on the lending them out sometime though. Got a dimpling jig but not a pinning jig.

I appreciate the offer and the advice. As it turns out, I have a buddy (and my instructor) who sells the VooDoo barrels (he's afifiliated with Huldra) and has the jigs and tools necessary to pin the 87 Industries gas block for me.

If for whatever reason your other deal doesn't work out,
Wes at MSTN. Offer to pay for whatever gets dicked up from trying to cut QPQ. He's a reasonable guy and if you're trying to do the impossible/inadvisable, he will let you know.
