Well I started an ar15 build about forever ago. I purchased a Magpul UBR because of how durable it is and I thought it looked pretty good. Well I'm rethinking my strategy now. Originally I wanted a somewhat light weight rifle, which the UBR is not. So I wanted to see what you guys/gals think. Should I keep it or sell/trade it for something like a Vltor Imod. And what kind of weight saving would I get by switching to an Imod with milspec buffer tube and endpapers vs the UBR. I like the way it looks and feel other than the weight of it. What do you think.
