They both shoot awesome! Both flawless with everything I've shot so far- .223, 5.56, and Tula. They both are 14.5" middies so they shoot pretty similar. The BCM has the Gunfighter mod 1 comp and the noveske has the battlecomp 1.5. Both do a great job keeping the muzzle down during rapid fire. I would give a slight edge to the BC if I had to choose but that noveske SS barrel is a lot heavier than the BCM BFH lightweight. Both did excellent. The BC was about 2x louder tho. There was more side to side movement during rapid fire than any rise, if at all. Finally put froglube to the test and it was nothing short of amazing to me. Doesn't looked lubed at all then once you start firing all the lube just pours out and all the parts are wet and runs smooth as butter. Really glad i tried it out. worked awesome in my G17 too. All brass ejected consistently at 4 o'clock with ST-T2 (Noveske) and H buffer (BCM) thru all ammo fired.
