I just got to setting up my HKP RMR mount and was going to put a 508T on it. The screws bottomed out before they seated all the way. Does anyone know if the RMR screws are shorter than the Holosun bolts? Should I just order the RMR screws from HKP? Thanks

For reference, I'm talking about this mount

The height where the screw makes contact with the body of the optic is higher on the RMR vs the Holosun.

The footprint is the same, but screw length will be different.  Holosuns require shorter screws.  You can trim them/grind them down.

I’ve had luck cutting screws that are too long with my dremmel.

I had this 508T mounted on an ACOG, and used the same screws (they worked great on the 12 o'clock mount). I may have the shorter screws in the box somewhere.

Thanks

Most mounts use the same thread pitch. Some do not.  Just make sure they’re the same before you give them a go.

Jagerwerks has many different screw lengths and options, so that is where I'll get shorter screws.

Recently tried one of these and the hooks don’t fully
engage below the tabs. I suspect I will need to remove
about 0.010” from each hook.  

Rather surprised it does not fit an HK SP5

How’s the sight picture on these?  I recently purchased an SP5K-PDW and have a spare RMR I want to use on it.  

On my AP5 I have a B&T rail with an Aimpoint CompM3 and ADM low mount.  That puts the top of the hood in the lower 1/4 of view and isn’t very distracting.  I’ve had setups in the past where the top of the hood ends up lined up with the dot and that’s no good.

It’s a perfect co-witness with the dot right over the front post. Not obscured at all with the front hood.  The only thing is any co-witness is busy with the rear diopter so I’ve changed mine to the castle style and a “v” notch one and that works perfect for me.  Very cool mounts and the best co-witness one out there from the many I’ve tried.

Ok cool, I’ll have to try one out.  I didn’t want a big claw mount rail on this one.  The SP5K-PDW comes with the castle rear sight and I was going to change that to a diopter but maybe I’ll leave it on if I go this route.

I’d leave it for now until you try the mount.  Much better than the diopter with the sight.

IMO these are too low, they're basically at the same level as the Irons, and if you have the rear site there between your NODs and the RMR, it's going to obscure and ghost the view a good bit.  Not to mention the collision potential with the rear of the receiver as you try to line things up.

I've run my AP5 with NODs, and I put the optic way up above the irons.

I’m running the Aimpoint Acro version. I had it out at a night shoot a couple weeks ago. I didn’t have any issues hitting steel plates using it passive. I honestly expected it to be too low.

Anyone try one of the Titan mounts?
I want a mount for a Holosun but HKParts is out of stock on their standard Rmr/holosun mount and only have their new style which requires an adapter plate so it ends up being almost double when all said and done.

Titan mount is only $65 but can’t seem to find any good reviews on it so very hesitant.

Would prefer the older style rmr / holosun mount from HkParts if they were available.

Give it a few days...I hemmed around and finally decided to order the standard mount (non-plate version) a month or so ago, and it suddenly went out of stock. I waited a few days while I contemplated/researched what other mount to substitute and it came back in stock. Glad I waited, I really like it.

I'm wondering if the Reptilia riser will work. I also would like to know if there are holes to stack on the boss posts.

The HKparts mount is the best one out of the three I've used, but I'd like to bump up the height just a bit.

I went with a American Defense MFG MRO mount for my SP5 SBR. It has the HK Parts rail adapter on it as well. I went with co-witness height. I've tried the low mounts for the RMR or other styles of compact RDS and just didn't care for them at all across several different PCC's.

The Titan mounts are good, better than the HKparts in my opinion.

I don't think anyone makes a single claw that holds zero out of the box however (within 5 MOA). I've been buying them anyways & tinkering with ways to increase the stability without the front set of claws, since I really hate the ergonomics of the full claw setup.

Are you getting a 5 moa shift with these in between range trips without removing them?

I agree you won’t likely find a single claw mount that holds a zero.  However given how the rear mount sits on the receiver it’s not very difficult to bed the mount to the receiver. You don’t need much bedding compound, just enough to fill the space between the recess in the sight and one of the lugs on the receiver. Neutral shoe polish in the receiver works as a release agent and a small amount of JB weld applied in one of the recesses on the mount will do for bedding compound.

I will bench test it before it gets any range time. They have to hold up to firm hand pressure (rotating) in both directions and a few raps with a screwdriver handle, without shifting before moving forward. They all rotate (yaw) to some degree.

Yep! I have had some success with this, or shims that fill the U shaped recoil pocket. The Titan mounts lend themselves better for shimming.

Same here.  3 of the hk parts rmr mounts and 3 that hold zero fine.  The optic weighs like 1 oz.  I’m not sure why one claw wouldn’t hold it tight enough.

A few taps with a rubber screwdriver handle will probably knock the HKP mount around, unless you have a perfectly matching receiver. Normal firing & light handling it would be fine.

For curiosity, I went to the garage and gave the mount/HS407 combo a dozen or so raps with a Brownell's 3/4" Delrin-tipped brass hammer and was able to get the dot to move slightly left in relation to the front sight post. Lesson learned...the mount isn't robust enough to take a hammer beating without losing zero slightly.

Mine could be twisted slightly side to side.  Not much, about 4-5 MOA change in windage at 100 yards, with no change in elevation.

It was still minute of bad guy but the MP5 is capable of better accuracy if you bed the mount to the receiver to eliminate the play.  

It’s not hard to do. Use neutral (or in this case black) Kiwi shoe polish on the receiver and lug for the rear mount as a release agent.  Then fill the forward recess on the mount with JB Weld, and reinstall the mount on the receiver. Let it cure 24 hours and you’re ready to go with a sight that won’t lose its zero, or move even with percussive maintenance.

——

One advantage of the HKP mount is that it is low enough to do witness with the iron sights.

I don’t really care about the back up aspect of that, but rather the accuracy improvement at longer ranges suitable to a MP5 SBR.  

For example, despite their ad hype the Holosun 507C has significant parallax at longer ranges out around 100 yards.  But with co witness sight capability you can zero it with the red dot right above the front sight post with the post centered in the rear aperture.  That will ensure your eye is consistently placed behind the sight.  And when shooting at longer ranges you can attain the same precise centering of your eye and eliminate parallax error.

At close ranges where parallax won’t matter, you can still shoot with both eyes open and use the dominant eye to put the reticle on target. It’ll still shoot one hole groups at 15-20 yards.

My post was more facetiously directed to the posters above me that suggested that the mount wasn't capable of withstanding anything more than a loud fart without losing zero or falling off. I went to the range yesterday and found that after the hammer beating, it was only off by @ .3" at 25 yds. I'm happy with that...I'm confident now that it will take what abuse I'd likely be subjecting it to and still be serviceable. I retorqued the screws, added a couple of right windage clicks, and was back to zero.

Reptilia riser fit right on the HKparts mount. I had to get new mounting screws to make it work, though.

It’d be nice if someone made a riser with an opening in the center so the irons are usable underneath the optic.

But the real question is why hasn’t anyone bothered making a single claw mount for a T2?

Titan just came out with such a mount after all lol. But, they're discontinuing it because it won't actually work with a T2, the dials and optic get in the way of the clamping screws.

I ordered the pic version instead.

Damn, I want to like the TTD mount but it just doesn’t inspire confidence.

It has quite a bit of side to side play on an HK, like 2mm. Doesn’t really make sense as to why there’s such a large difference, I might try shimming it. Bedding with JB weld is an option, but there would be no way to ensure it is centered.

That lends itself to uneven installation, tightening one claw seems to pull it to that side.

Claw contact with the receiver seems to be minimal and not that secure. I’m less worried about it marring, but it seems like the screw could break with a hard impact.

With tightening, the entire mount seems to flex, putting the claw contacts at an even more precarious angle.

It seems like the HKP claw design is a bit better, but I hate the shape of the pic rail, so not getting that.

I'm happy with that...I'm confident now that it will take what abuse I'd likely be subjecting it to and still be serviceable. I retorqued the screws, added a couple of right windage clicks, and was back to zero.

You edited my reply to remove this sentence where I said - "Normal firing & light handling it would be fine."

Everyone has different requirements / expectations for accuracy. I am HOE (hard on equipment) & don't feel like worrying about the zero after I finish mounting / testing.

Question from a MP5 newbie... are the double claw mounts better / more secure or do they also suffer from the same issues?

Should be better, four points of contact plus the recoil lug vs. two.

My MI rail has held fast for a few years now.

I don't think anyone makes a single claw that holds zero out of the box however (within 5 MOA). I've been buying them anyways & tinkering with ways to increase the stability without the front set of claws, since I really hate the ergonomics of the full claw setup.

Wait, are you saying these single-claw compact dot mounts don't hold zero and shift around? Are you mounting them towards the rear seat using the factory recoil lug, or are you mounting them at the forward-most claw area that doesn't have a recoil lug?
