Thanks for the heads up Affliction. I ended up installing the mods on my m4. You're right about the rail system. I've got nothing attached to it so far and it's already pretty front heavy. I think I should have went with a longer front.. seeing as I just fell in love with your M16... Looks awesome, great job. I'm waiting on my scope hood (finally found a place in B.C). Thanks for the feedback, really appreciate it. I'll post up new pics as soon as I get a chance. P.s. I may have to get an M16 now..
