Hi, i started airsofting about 2 months ago and the gun i use is a UMP45 HK Umarex Elite. And i do have a OD green facemesh with OD green gloves. But i do not know what do buy, my friends are telling me to buy a sight (its hard to use iron sights with the ump since you really have to get you're face into the stock) but i wanna vest so i can buy extra mags. Can you guys give me you're opinion and try not to yell at me or judge me.
