pretty slick

Written on Apr 06, 2023

Just installed it, did a couple dry mag changes to see how well it works and i think im about to order a bunch more. I used a stock milspec geissele spring bc its what was already installed and i noticed some giys say it was too stiff bc of that but it seems to work really well in this run of the muck milspec lower. If anything changes ill update this but i really like so far.

Look im gonna take the "L" for this one bc i shouldve read the product description bc the whole reason i got this was bc i thought it would be cheaper but this package doesnt come with a charging handle or Bcg so thats on me but im not gonna dis the product for my incompetence.
Out of the package it seems like a nice clean and well assembled upper. No marks or rust, barrel looks chrome lined. I honestly hate left handed uppers for ARs, they work right or left in its standard configuration.
For real though their is a brass deflector for reason my dudes.

Its my first 10.5 pistol build so i went with rosco. Watched a few videos and also checked out their website to read up on it. I wasnt sure what to expect but i was extremely happy with it after it arrived. No nicks or scratches. Comes dimpled and tye fit is truly awesome when putting it together. Used a geissele gas block that fit perfectly. Ive only put about 250 rounds through so far but havent been disappointed yet.
