Best 300 bo upper for ss? (self.general)

submitted 3 weeks ago by Darth_Slayer_12 to c/general

2 comments fedilink hide all child comments

I'm looking to print an ftn4 and have a fun time time with it. Was thinking of a 300 bo sub build with a super safety. Wanted to hear opinions on good uppers for it. Was looking at PSA's sabre-15 upper since it comes with some higher quality parts (adjustable gas block, plan b flash hider) (I am also willing to start from a stripped upper). I don't want the rifle to be a complete poverty pony but I also don't want it to completely break the bank. Any help is appreciated, thanks in advance

No experience with the Sabre line, but I've not been impressed with PSA's standard uppers. They're functional (mostly) but not very efficient due to some pretty lax QC standards. Maybe the Sabre is a lot better, but once you're over the $600 mark, it might be worth ponying up the extra 30% for a BCM.

Also note that if you only plan to run subs, the AGB doesn't really add anything since you'll very likely just run wide open all the time. The AGB really only helps if you want to run both subs and supers so you're not completely over-gassed on the supers.

I run a .300 blk 8" Aero upper with a Nomad 30 and a Super Safety.

It's good fun. Also LMK if you need a cheap Super Safety. I sell DIY Kits for the SCS Super Safety for $15. You just print the printed parts and I handle the metal stuff ;)
