After much deliberation, I decided to switch direction and go with 7.62x39 in my PDW build. I have no plans on buying a can, and with ammo being half, if not less than 300BLK, the proprietary parts made more sense.
Trying a BCA 7.5in barrel, and the AIM BCG to start. If/when the bolt fails, I'll likely swap in an LMT. CPD mags on order.

If you're paying for the ammo, I'll gladly stick with 300BLK! The fact is that 7.62x39 is substantially cheaper, and ballistically is approximately 200fps quicker than 300BLK, given equal barrel lengths and similar weight bullets. Expensive x39 is essentially where cheap 300BLK begins.Personal defense weapon should not be a caliber highly prone to failure in an ar platform. Before anyone goes crazy and comes in with the "x brand runs great" very few ar's run X39 without failures. The ones that run slightly better than most are well north of 1k. Then you have to figure out which magazines work with which ammo. Magazines are very pricey, you also are limited on what magazine carriers will hold the banana X39.
I've never seen an X39 ar finish a class without multiple fails. For a deer rifle that only ever sees slow fire, it can be ok. Still not as good as 300blk, especially in a personal defense weapon.
X39 and 300blk defense ammo is equal cost wise. 300blk has much better extreme short bbl performance as well.
If it were me, budget building with bear creek, there is no way I'd consider X39 for anything other than a vanity round for an ar.
The top is a Bushmaster A2 "ish" factory rifle. Just something to remember old days.
The bottom one is a PSA CHF mid length dissipator upper, and it's all PSA except the the RRA Entry buttstock. I've had and always liked dissipator style AR's and wanted to replace the ones I sold in the spirit of fewer moving parts. I hardly ever adjusted a collapsible buttstock beyond where this one is at anyway so it just made sense. I tried something similar years ago with the magpul fixed stock, but it was much longer. Just got it completed this week so the jury is still out on it's reliability and performance, but I've never been disappointed with a PSA CHF upper. Time and empty cases will tell.

Appreciate the input, and all of those points have been considered at length.
Bolts and magazines tend to be the major failure points. CPD magazines are roughly the same price as current gen Pmags and 300BLK specific mags.
The only BCA component on the pistol is the barrel.

20-30cpr .300BLK is being released this month. Wolf steel. Cheap enough?If you're paying for the ammo, I'll gladly stick with 300BLK!

Definitely gets it in the conversation, and may explore the caliber in the future.20-30cpr .300BLK is being released this month. Wolf steel. Cheap enough?

Feels kinda ironic to me, my first ar I had was a dissipator then I sold the second one to you. I always liked the look of a dissy in a stubby stock. The irony lays in the fact that I had a stubby stock on it at one point in time.
I'm glad it's at a good home!
and other configurations...
Man I appologize, but what rifle did I buy from you? It's been a years and AR's ago?
Whoops! looking back at my PM's it looks like I didn't sell you my dissy (you did pm me about it though), serves me right for playing on the forums while sick lol.
And a new tripod.
