This is true, but for the price you pay for the TM M4s, its a solid package. The critical stress points and rails are metal. Of course, on a real steel M4 and SIR you need light-weight machined aluminum because the heat the gun generates would melt plastic, but lucky for us in airsoft, thats not the case. Basically, the SIR on TM M4s is strong where it needs to be and doesn't need to worry about melting so it can use cheaper/lighter ABS in the body and metal in connection points and rails, which saves us weight and cost for similar durability and gives us the same effect for a fraction of the price. Having said that, one could always outfit their favourite m4 with an ARMS SIR for the meagre sum of the cost of the gun + 399USD. Plus the rear flip up sight - 99USD. And front flip up sight. And swivel sling mounts.
