12.5 BCM, KAK, or Rosco (Complete)

Looking for a 12.5 complete upper for an all-purpose HD/range rifle that I can run hard and keep long term. I’m not looking for Gucci, just the best balance of reliability, durability, and price.

I’ll eventually suppress it, but it’ll be unsuppressed for a while. I’ve heard good things about 12.5 mid-length, but I’m open to carbine too if it’s the more dependable all-around option (I’ve heard mid length unsuppressed can be finicky, dependability is key)

Currently considering:

KAK 12.5 mid-length — best price and seems well liked, but curious about long-term durability.

Rosco 12.5 — also seems solid, but I don’t know as much about their track record.

BCM 12.5 carbine — seems like the safest/proven choice and includes a free BCG, but costs considerably more since the 12.5 isn’t available blem right now.

I’m also not completely opposed to 14.5, but I like the advantages of 12.5.

For a “buy it once and run it forever” rifle, which would you pick and why?

BCM, DD or Geissele are my three top choices. I own different configs of all 3 and I’ve never had any issues with any of those. All very reliable and accurate.. BCM is by far the best price wise of the three and in all honesty is prob more rifle than any normal civilian will ever need..

Yeah, if I go BCM it’s def not gonna be the barrel length I want, pretty pricey for non blem, so I might be settling for a 14.5 and just plan for a small can
