Really, i think i saw someday someone using M27 IAR too... hmmm, but they werent sof i think.. Except the M27 is not the same thing. Its an infantry automatic rifle, not a carbine. I was only listing carbines, since were on pistons lets add the M249, Mk48, shall i go on? Quoted:
Ok, and M16 and M4 is the same weapon  practically they are |

http://militarytimes.com/blogs/gearscout/2011/10/24/whats-the-diff-between-the-m27-iar-and-the-hk416/ The M27 is a longer barreled 416. The only other differences are accessories. The M27 IAR is used by Marine infantry units, but just started being phased in. Are you kidding? The significant major difference is the IAR fires open bolt after the first round. The bolt only moves forward to strip the next round into the chamber after you pull the trigger. This has several advantages for an automatic riflemen, mostly in relation to heat. Not round sitting the chamber getting hot, and more cooldown time for the barrel. Watch this video of the LWRC IAR to showcase this difference. http://m.youtube.com/#/watch?desktop_uri=%2Fwatch%3Fv%3D2YzGzeLh3mc&v=2YzGzeLh3mc&gl=US |

The M27 IAR doesn't fire from an open bolt, ever. [quote =wikipedia] Design ↑Jump back a section See also References External links Type your search here... The M27 is based on the Heckler & Koch HK416, which in turn derives from the M4 carbine and Heckler & Koch G36. [15] It features a gas-operated short-stroke piston action (instead of the traditional direct impingement) with a rotating bolt. The weapon also fires from an open-bolt position in fully automatic, like many traditional machine guns, however, upon switching to semi-automatic fire the first round is fired from an open-bolt and each round after is fired from a closed bolt, like traditional assault rifles. It is modified with a heavier barrel and includes a bayonet lug. The free-floating barrel is surrounded by MIL-STD-1913 Picatinny rails for use with accessories and optics. It draws ammunition from any standard [/quote] |

Ok I stand corrected. Every source speculating on the M27 IAR has always assumed it was open bolt because simply a closed bolt doesn't make sense???? Of all the competitors, the H&K was the only closed bolt design.
So from the specs it looks like the only difference between the M27 IAR and the M416 is 2 inches of barrel length, and speculative a heavier barrel profile??? Why bother calling it an IAR, why bother having another gun besides the M416??? The extra 2 inches of barrel length will add maybe 100fps at most, which is really negligible. So why bother???? I really can't think of a legit reason, maybe someone else can enlighten me. |

So, it begs the question : what are the differences between the m27 and the civilian MR556A1 besides the full automatic mode and all the enchilada associated with supporting sustained auto mode?
In other words, is the MR556A1 worth the $3k, keeping in mind that there are other short stroke piston rifles like LWRC, LMT and Colt that will cost around $2K? |

Video states the M27 IAR is bolt closed on semi and Open on F/A fire.  http://www.youtube.com/watch?v=OukIvPxdakwWhere is my facepalm .gif That is not the M27 IAR, that is the entry from LWRCI that did no perform that well. Im telling you r0n you cant reason with some people when it comes to shitopedia and future weapons(the same thin that said you cant fire the M4 when its upside down) |
