I used an ar stoner side charging upper on my grendel which is a heavy long range gun. It is reciprocating right side only. It appears overly built and petty heavy. My gun shoots great but I'm not sure i gain anything other than being a little different. Luckily the standard uppers and side charging seem to be pretty close in price. My next one will be an sbr black out and will probably be t handle like my other battle rifles. I like having options though and playing with my black legos.
