| hey guys what are you guys using for an offset mount for the rmr? I want to mount the rmr in conjunction with my leupold mk4 but there doesn't seem to be too much available as of yet. maybe I missed something in my search. so what do you guys do? |
|
I say definitely off the rails. If the RMR is piggy-backed on top of your primary optic, you will have to pull your head and cheek weld off of the stock and this causes unwanted head movement and also gives you less control of the weapon, your cheek being an added point of contact and stabilization. If the RMR is positioned at the 1 o'clock one quick 5 degree rotation on the weapon moves your eye back and forth from primary to secondary reticle very quickly allowing your cheek weld to remain steady.
Couple options: 
DD Offset

Daniel Defense, LaRue Tactical, Gear Sector, and YHM all make mounts that will work for you. TNVC also makes a scope mounted offset mount. Hey bud thanks for the info. I'm aware of the yhm, and DD mounts but I believe Larue only has mounts for the dr optics RD. I just checked gear sectors website and couldn't find any mounts for the RMR do you have any links? much appreciated JD |

TNVC ring mount Looks like as long as you get the picatinny base for your RMR you can use any of these in addition to the YHM & DD.....unless im totally missing something. |

Wow nice work brother. That gear sector mount looks great ESP in FDE since the rest of my rifle is FDE! I wonder if anyone is using the gear sector I'd love to know if it works out well! hey man thanks again! JD Glad I could help. I wouldn't worry about Gear Sector. Quality products all around. I have their offset Surefire Scout mount inbound. |

I like 12 oclock mount ––-I use a dedicated SAR mount from TNVC on top of my Leupold prismatic.
in a cqb situation I think that having your head up and not buried in an optic would be intuitive and work well with the two eyes open reflex RMR design. cheekweld to jawweld––jaw weld position maximizes your awareness with head up. one thing I just dont like about the offset mounts is that it will complicate or ruin your zeroing––especially if the sight is not mounted perpendicular to the bore. just my opinions.......... |
| Look at what competitive shooters are doing, it's by far the most common setup when using a secondary optic to use an offset mount (or a handguard like the JP/VTAC that lets you attach rails right to the handguard in an offset position.) It's faster to shoot that way and you don't have to break your cheekweld to do it. Further, it keeps the optic lower to the bore, which is what you want for a close range setup. I never understood why people were so determined to mount their close range optic on top of another optic since they end up with a massive sight offset, not to mention you have to break your cheekweld to use the optic. |

That might be what competition shooters may like and these mounts do take a more than 5 deg cant to see the dot. Also, keep in mind for shooting prone it's VERY difficult using a these offset rail mounts, plus the turrets get in the way with some scopes regardless. With our TNVC SAR, you can mount ones RDS in ANY position you have room for and that includes a 4:30 low or 2: o'clock position while STILL keeping a cheek weld. That is the beauty of the TNVC SAR unit. Hope this helps.

Vic The turret issue is valid and something to consider, but I've never had a problem shooting under barricades or anything and I know plenty of other people who use offset mounts who haven't had problems either when shooting prone. |

Not to argue the point, but canting a weapon while on a bipod or not and trying to twist the rifle way over 5 degrees which these offset mount use, is no joy while shooting prone. This IS and one of the main reasons the new Army Quick Fire solicitation has ONLY called out for a scope mounted mini RDS system and not a rail mount system. Hope this helps.

hey guys what are you guys using for an offset mount for the rmr? I want to mount the rmr in conjunction with my leupold mk4 but there doesn't seem to be too much available as of yet. maybe I missed something in my search. so what do you guys do? I'm currently using the SAR mount from Victor at TNVC. I use both an Aimpoint T-1 and a Trijicon RMR 4 MOA this way. You can place the RMR between the windage or parralax turrets (depending on left or right handed shooter) and the elevation turret. For me, even shooting from standing or kneeling positions, I much prefer this mounting (I am a southpaw). Rotating the weapon 45 degrees just doesn't work as accurately, or rapidly, as rotating it 5-8 degrees with a slight rise on my cheekweld, at leasst for me. This allows you to shoot from prone as well, as only a positional change in cheekweld is required, as opposed to rotating the whole weapon (not practical from a precision prone firing position) to bring the RDS onto target. It is a little more "heads up" cheek, but that's actually an advantage when rapidly transitioning between targets that are say, 400 meters away vs ones that are only 30 meters away. My RMR has actually been very surprising, mounted on both a USO SN-3 as well as a Nightforce NSX 3.5-15X50 on 16" to 18" ARs, results have been very encouraging. Not to say that my 18" SPR is going to replace my 10.5" LMT/M4S Aimpoint equipped SBR as a home defense gun, but with the little RMR mounted on the SAR ring, it could! |

wow so many options here guys!! How bout some pics to better illustrate these set ups! Again, I've never ever had a problem shooting with the red dot prone, and I've never had a problem rotating the gun to see through it. The low sight height definitely helps with close up shooting.

That gear sector mount looks great ESP in FDE since the rest of my rifle is FDE! I wonder if anyone is using the gear sector I'd love to know if it works out well!
We just finished T&E of our offset mount. It has entered production and should be available very soon. That said, it works extremely well with a variety of MRD's as well as its intended purpose of running a Surefire X300. How bout some pics to better illustrate these set ups!

| Just a note to the OP. If you decide to go the route of running the RDS offset on the railed hand guards then you will want a free floated set as non-free floated rails will give you some trouble holding a zero with the RDS. If holding a perfect zero isn't necessary and 1-2" of movement on target at 25y is within reason for what you are going to be shooting then don't worry about free floating. |

maybe if I list my specs it'll help narrow down the choices. here they are as follows:
Noveske N6 with... tag for pics but my specs are as follows -Noveske N6 lower -Magpul PRS -Armalite LPK w/tactica 2 stagel trigger -Magpul MIAD -Magpul MOE trigger guard -BCM gunfighter -Scar rail panels -Armalite upper -Noveske 21" fluted SS barrel -DD 12.0 lite rails -Armalite BCG w/FA -AAC 7.62 51T Brake -Larue Tactical/Harris Bipod -Leupold MK4 6.5-20x -Trijicon RMR -Troy FDE BUIS so seeing how the MK4 has a parallax turret on the left side I'm worried that rail mounting the RMR the view will be obscured by either the parallax or windage turrets. what do you guys think? |

Folks can take a look at this video TACTICAL GUN FAN PART 2 where we talk about the SAR unit and perform a live-fire video clip toward the end showing minimal head and weapon canting movement while using the SAR 3 with an Aimpoint Micro T1. Hope this helps.

Does not compute well I finally got to the range and the 12 o clock rmr worked great for what it does. RMR is 3.5" over bore and the leupold prismatic is 2" over bore. 7moa Tritium/FO rmr zeroed for 50 yards prismatic zero @ 100 i am thinking of zeroing the rmr @ 100 ALSO... |
