First post and I'm terribly sorry if this has been asked 1000x but here goes... I'm new to airsoft and have a Walmart Ignite Black Ops M4, Black Ops 1911, and an HK Dual Power G36C (yeah the full Plastic one). I like them all and they all do the job reasonably well, but I want to upgrade my two rifles. I'm pretty happy with the M4 and 1911 honestly, but have no idea on the longevity or quality of the Black Ops walmart stuff. I know that I'm going to get an Umarex G36c, but I can't decide on whether I should get the Umarex G36KV or a G&P M4 full metal to compliment the G36. The budget is $380. I can get the G36c for $150-ish, so that leaves me $240 for another gun. I guess the BIGGEST question is should I go for the full metal G&P M4, or the G36KV with scope to complement my G36C. I just hate to get another M4 when the Black Ops is working just fine and I'm pretty pleased with it. Also, one last off-topic question...is the Umarex stuff pretty good as long as we are talking about the $150+ stuff and not the dual power guns?
