Kwa sr10 rm4 aeg3 with 2 uppers. One user is for normal field lengths, one upper was used as a dmr. Internals are stock except for a solid cylinder installed and a spring upgrade. Don’t remember what spring is in there, but last I played I used it was firing around 400fps with .32g. Each upper had a prowin HopUp, with prom rhop inner barrels. Both uppers shoot very accurately. Comes with 4 30/120 Mags and 4 short 70rd mags(? I forgot the capacity, also some of these mags have internal problems, sorry, unsure which of them are like that). No battery included but highly recommend using a 11.1v limo with this. Also has been converted to Deans, but including an adapter I made for the more common connectors. Being sold all together, will no sell uppers separately. Sorry, no trades
