[QUOTE="ARlife4me, post: 2701193, member: 105694"] There are reasons for h3 buffers and higher spring pressures also.................save bcg or do you want a blowback 5.56? no thanks! I have rifle length on 20"ers, but couldn't get it on 18's (intermediate) and 1 16". Gas port size is extremely important for sure regardless of cartridge and barrel length. +2 on a 24" 5.56 is ridiculous, but doable if the have the proper bcg, buffer and spring! Wanting that dwell time can cost you IF you don't have enough pressure due to which powder you use. Fastest powders will drop like a lead balloon. [/QUOTE]
