 Here's a lug I cut off from a FSB and drilled and tapped for setscrews to go on a barrel with a short low profile gasblock. there's barely enough room to seat it on the journal, but it does fit, and works fine. |

Quote HistoryQuoted: So I've been giving this some thought. Has anyone ever chopped their sight tower off of the block but kept the bayonet lug on it, and also chopped just enough of the bottom front of a free float to effectively mount the bayonet? I actually took one of the $35 keymod rails Geissele had on sale a while back and did just that for a 16" carry handle upper. I dont have the picture it looks like but I cut the top of the handguard to clear the FSP, and removed portions on the bottom to clear the bayo lug and sling swivel. I think it came out pretty clean until I added holes to get at the FSP pins. Next time I am around the rifle I did it for I'll grab some photos. |

I also had to shave the back flange of the block to get the contour to fit inside the ALG handguard. I would prefer pinned rather than set screwed, but assembly would be problematic.

I think it will hold with loktited set screws I was thinking of using a LaRue LAT in 13" and have some of it overhang with the bottom cutout from the lug forward, so I can still have some real estate for active aiming with a laser and a scout. But then I started thinking of the barrel and having just enough to where I can still shoot from a barricade without having to worry about barrel bounce. I also thought about whip with a pencil and how counterintuitive it could be to preventing barrel bounce. A tapered barrel like from Criterion's Core or some other could actually be better for what I am still thinking of. Thoughts? Nice build buy the way. |

@Jonny1904
No, it's a faxon 16" gunner. the longer flash hider is not needed. the bayonet ring sits at the right location on the FH base. if you use a 14.5 with a PW extended phantom flash hider, the ring sits right at the forward end of the flash hider, right where the front slots end. It works fine |

This was for a 16" carbine gas with A2 upper and FSP. This one would have the floating bayonet issue if it was mounted due to carbine gas, but now at least has a free floating rail and attachment points. This was for another person though. I don't currently have any that use a FSP due to cutting them all down or using low profile gas block with free floating rails. I do have an M7 that is lonely, so I need to just pony up and get the G adapter. |

Quote HistoryQuoted: take that space you would carry said bayonet and add 1 extra magazine. That 30rds will make far more difference than a bayonet. Unless you want to play SOF dress up with your rifle, then yes indeed, add a bayonet you are guaranteed to never use in your lifetime. And if your gun has a malfunction and needs to be taken apart to identify the problem and fix it? Extra mag is worthless. |

I hate all the horrible looking adapters to make one fit a 16” carbine barrel. One of these days I am going to cut an M7 mid-handle and weld in an extension, and make it work. Hard part is making new scales. In the meantime I have to use a 14.5” SBR or a 14.5” with a pin/weld extended flashhider.
there has to be a market for a good, simple, normal looking bayonet on a regular 16”. It is the most common configuration found for carbine barrels, whether or not it is “ideal” is a different matter. Why build ugly adapters when an extended handle bayonet is the correct answer? I understand Colt once made a limited run of them, but I don’t have one... |

If it makes you feel better, have a machinist make you a collar with a set screw to take the slop back down to A2 birdcage levels. |

There's some value of having a bayonet. I wouldn't want to get in a firefight with one fixed, but if you were holding a few perps for the cops, there's some serious psychological value beyond a barrel being pointed at you...it's the tangible effect of seeing exactly what is going to go in your body if you don't comply.
I've had discussions with Gurkhas regarding their khukuries and the psychological fear (and their reputation) it has on the enemy. I've worked with Afghan forces where an AK or M4 is "meh", but they respect blades. And of course, the most reasonable use of a bayonet is to conserve ammo when the zombies are down but not out...coup de grâce with a blade is simply cheaper  ROCK6 |

As long as you're using a quality rail it should be fine. They climbed trees with it and stabbed cars with it after prying stuff. Apparently it was a pretty fun job. You just got to completely abuse a rifle with a bayonet attached. They released a few videos of the testing but it's either on IG or FB I forget which. |

I found a shop local to do the work. They can cut and shape the lug part of the block, have the jig already to drill the barrel for the tapered pin, will be mounted ahead of the already pinned SLR gas block, have the mill to chop a small portion of the bottom front of the RHF tube and will refinish for under $200. Totally worth it to me and will be dropping it off sometime next week after the parts from BCM arrive.

Quote HistoryQuoted: Aside from the handle I like, what makes it good? Quote HistoryQuoted: Quoted: To call the OKC3S a really nice Ka-Bar style knife is a disservice to the OKC3S. We put a lot of effort as a service into making sure our newest bayonet was state of the art. It is fantastic as a military weapon. Quoted: Agreed- I'm not trying to sell it short, believe me! If one can only pick one AR bayonet, get the OKC3S, hands down. Aside from the handle I like, what makes it good? The Marine bayonet has solid tang construction. Not sure if I said that right or not, but it means that the blade and the part underneath the grip are a single piece of steel, like the old Marine Corps/Navy KaBar knives. OTOH, the Army bayonet is not, and is not as strong. |
