        Hey guys…

        I was curious what the differences are besides the m16 BCG weighing more?

        I have always kept a couple of extra bolts around, and one of them is an M16 style. I am getting ready to put together an 18″ rifle, and thinking about using that BCG. Thoughts?

          I know the “M16” BCG’s are popular as of late.

          But all they do is add a small amount of moving mass.
          Its perfectly usable but the benefits are dubious.. I mean who has ever, and I mean ever, seen a BCG break?

          A M16 BCG could be an advantage of you run hot ammo.. say federal Xm855 on a rifle whit an overspec large gas port..

          This can prevent excessive wear on the gun and especially on the bolt and clean up your spent case ejection pattern.

          But unless you have that larger gasport otherwise they dont do anything meaningful except the coolness factor

          On the contrary if its a in spec gas port, maybe even paired with a heavy buffer (which are also popular lately, go figure) you may lessen reliability as the danger of failure to lock back the BCG or even short stroking increases especially as the rifle gets dirtier (or fires softer loaded ammo).

          In summary there is really no practical difference in an M16 BCG’s function over a Semi BCG except where it comes to tuning your gun.

          By itself and not in combination with other factors the heavier BCG will do little, to help or mess up, your tuning.

            I have all M16 BCG in my rifles. On the off chance Full auto should ever become available again. If bad things should happen, the chance of battlefield pickups are high.

              IMO, the only benefit to rocken a M16 BCG is if you are planning on drilling a few holes and taking a dremel to your lower, post SHTF. ;-)

              On another note: Post SHTF I am very happy with the semi function of my long gun. One shot = 1 hit due to ammo reserves.

                Yup. Two pins and slap on the picked up lower. Same optics, same zero, etc.

                OTOH, I’ve never used hand held auto in combat. We had to qual with it, and most of us could shoot a better score on semi. The time limits were generous though.

                If I had an AR15(?) BCG, I wouldn’t sweat it.

                    In times of chaos, things magically become more available.

                    I’m jus’ sayin’

                      The only drawback for me is the late Andy Ginn worked my trigger group to nearly match grade on standard parts. I’d have to be in danger of being overrun to give that up.

                        As far as those battlefield pickups go, you’ll mostly find them with the crappy 3 round burst trigger group, which I could do without. However, the Army is transitioning from the M4 to the M4A1 with the full auto trigger group, so let’s hope this is all academic for at least a few more years.
