Help with 5.56 pistol upper- JP or Triarc

[NthDegreen]

Hey guys, here's what I've settled on for a PSC-11 dual charging pistol upper. 7075 T6 billet, I have my own lower, same material. Was considering a MK18 in 10.5, but am now going 11.5" barrel.

What i'm looking for is your thoughts on JP vs Triarc barrels and rails... mainly barrels, i'm sure rail is more personal preference... hearing good things about Triarc, but have known of JP for over a decade...

Either a complete JP upper from them ordering now- 16 week lead time. Their Enhanced bolt and full mass system, silent captured spring for law tac folder in H2 buffer, they will cut down their 13.5" stainless 1:7 twist barrel to whatever i want- 11.5, 12.5, etc. base price $1800

Combo of Triarc and JP- I source from Brownells the PSC-11 builders kit- PSC-11 upper receiver with JP bcg- enhanced bolt and full mass, SCS law tac spring kit in H2- around $1000. Then I send that to Triarc for them to add their 11.5" Track 2.0 single edge polygonal rifling proprietary system in their NP3 finish (supposedly very accurate), gas block, Wedge 7 hand rail, and do a custom cerakote on everything including my lower ($480+275+200).

Order the Builders kit and parts from Brownells, then do a separate barrel only kit from JP, probably the same lead time and similar cost...

I cannot help with every part you are looking at. But, I am really happy with my Triarc barrel and handguard. Barrel is light and very accurate. The handguard is very comfortable and rigid and stiff. A great rail to mount optics, IR devices, lights, and bipods.

I had a 12" Triarc rifle to T&E for a few months (thanks for the extra time, COVID) and it shot decent ammo, and even our cheap white box Winchester 55gr training ammo better than I would've expected, and our 55gr Hornady GMX about 1 MOA tighter than any other gun I've shot it in.

I'd have no issues running or recommending the Triarc.
