For a Naval gun, the Mk18 Mod 0 used either a M16A1 or M4A1 lower. Some had the Crane Anchor as shown in picture above but not all did. Mk18 Mod 1's (block II) used M4A1 lowers and crossed out the M4A1 to add NAVY 18-1

SF gun didn't issue any Mk18 Mod 0s with FSB. SF guns were all Colt M4A1 marked. ODA's never got any M4 with burst. Always been M4A1 with auto. Upper Receiver Group either with a 10.3" or 14.5" and DD RIS II rail would have a M4A1 lower. Some replacement guns have been seen in Group Support Battalion that used either a Colt or FN M4 lower converted to M4A1 standard however.

Would an LT104 work to keep the rail true to the upper during assembly?

Nah, the EXPS bridges just enough to do the job. I've been using them for a while to align when building/rebuilding and it works nicely. Granted, I've never tried cranking down the bolts unevenly or anything, but it always keeps it aligned if you cross torque evenly. |

Hey guys,
I have searched for an answer to this question with no clear results: In regards to the Tango Down Stubby VFG (non-QD) what is the proper mounting orientation? The grip is not perfectly round, has TD.com markings on one side and a protrusion/hump on the other side. Based on people's pics, i've seen it mounted 50/50, "TD.com" markings to the right and/or left side of the rife. I have tried both ways and to me, feel-wise, makes no difference. Thanks for any insight. I'm just wondering if there's a standard or recommended way to mounting the grip. |

On the QD version, TD orients the markings and locking mechanism on the right (assuming you're gripping with your left hand), which would argue for that being the "intended" orientation. That's also how I prefer it; I find having the tapered hump facing into your palm to be the most comfortable/natural position for a C clamp grip. That said, it's a matter of preference. |

I actually went through the same thought process as you, even though I don't have the QD version. Therefore, my non QD stubby has been mounted with TD markings to the right as well. Thanks for the insight. |

Here's another question I have been unable to find definitive answers to:
For my fellow clone history nerds, this question is regarding the MK18 MOD0: (i'm aware of the varying nomenclature pertaining to MK18s vs CQBRs) Is an "old school" gray Colt M16A1 lower "correct" or kosher for a retro MK18 MOD0? I ask because I know the CQBR as well as the SPR were fielded as upper options prior to CRANE taking over and issuing them as complete weapons. When CRANE did so, they fitted the CQBR and SPR uppers onto surplus M16A1 lowers. I have seen plenty of images of M16A1 lowers fitted with "CQBR" uppers as well as "SPR" uppers. Some of the "SPR" references I have seen are mounted on gray colored M16A1 lowers. I have even seen a "SPR" upper mounted to a late-60's slab-side M16A1 lower. So the question remains, could a completed MK18 MOD0 ever have come on a gray colored M16A1 lower receiver? Thanks in advance for any insight! |

ATACR 1-8x is the fix, apparently, but at double the cost :). Not that the x24 eyebox is great either I suppose. Still a used 2.5-10x24 comes in kinda close to Razor pricing really, getting a bit more long end, giving up 1x of course. I'm leaning towards the Razor TBH... just trying to look at all options before laying out the cash :). |
