10.3 with low pro gas block
Written on Aug 05, 2026
Idk if they still have it but i bought my 10.3 with the bomb proof low pro gas block pre drilled and easy install. Ive had this setup since 2018 and she still goes strong. Its only been like maybe 2000 rounds but the consistency and accuracy from 25 to 300 yards has been immaculate. Ive had it setup up suppressed with an RC2 pretty good on gas but its an AR not much you can do to mitigate the gas. I know modern tech seems to be driving more towards 11 and 12 inch carbines but if you really want a mk18 style just for the fun of it this is probably the best option
pretty slick

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.
