So I weighed my recon and my tm10 with a 20" barrel. the recon was only 10oz lighter. so whats a guy to do but put it on a diet. took the quad rail off and chucked the barrel up in my little lathe and got 8oz off the barrel under the hand guard without being very aggressive. ill do some more there if I can ever get a standard barrel nut out of dpms. also changed out the moe stock and grips for a ctr with a thick pad and k2. this required a mil spec buffer tube. these changes saved an oz. next up is most likely taking the quad rail to a single rail.
