So, I have a few rifles, mostly PSA framed with tasteful upgrades. I don't tend to cheap out on optics, triggers, etc. currently I have a Jakl, and a 300 blackout SBR.

Anywho, I took advantage of the Geissele blems sale, and would like to start a "Top End" or "Gucci" build.

So far, I have a rail, lower, buffer tube, charging handle all from Geissele.

I guess what I'm looking for is advise for internals and other parts. Was thinking of going BCM for the bcg, and would typically like an adjustable gas block.

As far as a barrel goes, I have been looking at the PSA FN chf chrome lined they have.

Any other suggestions? Better barrel idea?

The rail is a 13.5" and would like to keep the barrel relatively short.

Give me advise on good parts and suggestions! This build will take time, since I'm going to be using more expensive top shelf parts.

Thanks!!
