Well, I had eschewed top mounted RDS before but maybe they will get a second wind with all of the high mounts in use these days.

It’s a good way to try the high mount, but for me it’s just not ready for prime time. My only issue with top mounted is the two different cheek welds needed between the primary and the secondary optic. You said you eschewed them, so I’m guessing it’s for the same reason I did.

I didn’t mind the two cheek welds as much as I minded the HIGH cheek weld of what I considered the more important of the two sights: the CQB RDS.  

That being said I am about to go balls deep on a 1.93 mount so what do I know.  How high is the RDS?

Wouldn't a LaRue RISR stock attachment  help maintain a more "normal" cheek weld with the tall mounts?

Maybe.

I have a larue risr on a gun, but that gun has what could be considered an absurd height. 2.33 plus hk receiver height so at least 2.5 something.

The risr is great for tuning that personal preference index point when using high mounts if the lower jaw/chin weld is too weird. You still get the tangible benefits of lower stock placement in the shoulder pocket, a more heads up posture, and less neck fatigue. The gun just contacts your face in a different spot.

Some people may like it and some may not. I personally don’t really prefer it, but it does bring back that one nighttime gun back into the realm of a more normal high mount and helps balance it a little better. Still testing it.

yes, while completely removing the point of the tall mount.

Not necessarily. You still get lower stock placement in the shoulder pocket, less tension in your neck hunched down to view the sights, and a more fluid overall posture. With the high mount, Your head is in the exact same position as if you didn’t have the risr. The only difference is that the place where your face indexes is changed.

That said, I am still testing it. It’ll probably stay on the one Setup I mentioned above, but that’s a special case. I’m certainly not rushing to put risrs on all my guns. Like everything, I would say for people to try and evaluate how it works for their physiology.

Super nice setup!  Who makes that grey Upper and is it anodized?  Type 1 or type 2 hard coat?

@slappomatt
@BravoSierra
Sorry Brother but... LOL...That was pretty good!

@M-4matus

It’s a Hodge Defense Systems upper in titanium gray. I believe both the rail and the upper receiver are type 3 anodized.

@
type 3?  I didn't even know there was a type 3...  Whats the difference between type 2 Hard Coat and Type 3?  
If you can, please send a link to their website or a known dealers website.  I need grey now!!!

Later Brother

Very nice!  Although, IMHO, the Mod 2 E3 is has a bit more comfortable rail, yours is probably the best looking KAC Rail ever made...Probably hands down!

Here is my latest KAC Build.  Mod 2 E3 14-5 P/W Upper with Sandcutter BCG.  Still waiting on a KAC Ambi Lower and 5.56 Can...Shipping is crazy, almost as bad as the ATF these days!

All of this high-mount porn is going to cost me money.

Well worth it my friend...You'll love shooting with them, especially with a vest or NODS.  GL, don't spend it all!

@Cartel-
Almost seems like LMT makes these KAC Lowers and KAC Mods them.  I have thought this about many KAC items I have seen in the past.  Does anyone know if this is the case or if LMT & KAC collaborate on parts?

Okay phase one of my rebuilds is almost complete.  I re-configured and repurposed my cheap aero/faxon truck gun into a dedicated HD gun for my wife.  The POU being a handy gun that is easy for her to use (she has much more experience with AR platform weapons than any other and she isn’t the most competent pistolera) and won’t absolutely destroy everyone’s hearing.  I also won’t cry a river if it spends a couple years in an evidence locker in the unfortunate event it ever has to be used in self defense.  So when we are at home and my do-all BCM 11.5 is in the safe, this gun is staged as our GO-TO home defense platform.




- Aero receivers
- Aero LPK (ETA: I was mistaken.  Spikes LPK)
- Faxon 10.5” socom barrel I got on sale for less than $100
- BCM PMT trigger
- LMT BCG
- MCMR 9
- SBA3
- MCMR Mod 3 grip
- swapped the faxon gas block for a SA adjustable gas block
- Had my AAC 556-SD modified by Ecco Machine to accept the keymo threads.  Currently using a Q plan B and cherry bomb to obtain a reliable direct thread mount.  This gun is tuned to shoot only suppressed.
- Sprinco Blue spring and H3 buffer.  The gas port is fucking huge at .080 (I pin gauged it) so with the can attached even this heavier set up is not enough.  With the bleed off set to the MAX I am just BARELY able to get 3 o’clockish  ejection.  I am not really comfortable with that and will be obtaining a heavier red spring.  I will re-tune the gas block to that in the near future.
- Holosun HE515GT-RD.  I have used this on several guns since Feb of 2019 and it is awesome.  I have put a lot of rounds through it and trust it very much.  That having been said, I will be slapping some MBUS on it soon just in case.  I have this in a Geissele absolute co witness mount because my wife is short.
- Re-purposed surefire X300 with a switch kit
- it’s not shown but I have a proctor sling on it.  Will probably switch to a VTAC because my wife does not have the patience to learn the eccentricities of the proctor sling.

In its time as my truck gun this gun has proven itself many times over with approximately 3000 rounds down the pipe.  Now after the re-fit, it still holds 1” at 50 yards on a B8 bull with cheap 55 grain and minimal effort.  ETA: I know to some that is unacceptable, but for the previous and current POU, the cost of the barrel and the inexpensive ammunition, I think 2 MOA is highly acceptable.  YMMV.

Back in the day when I was a huge LMT fanboi I had heard tell of a close working relationship between the two.  Especially concerning the MWS and KAC AR-10s.  But it was a long time ago and I can’t cite anything or even remember where I read that, so take that for what it’s worth.

Love the SR15s.

Love it.

@amediocreshooter

Why did you delete your pics? Very nice gun.

Eh. Not really a fan of putting pics of the boomsticks online I guess.

Thanks for the compliment though.

how do you like that holosun? my 14.5 needs an optic, was thinking that and a g33.

A couple of slight modifications:



Upper:

Triarc Systems 11.5" bbl with .48 gas port
Triarc Systems 10.75" Trilok rail
Aimpoint T2 in LT660 mount
Magpul Pro BUIS
Surfire M600 with SR05 and Arisaka offset MLOK light mount
Griffin M4SD-K can with Griffin Hammer Comp mount
Armageddon Tactical ambi CH
Magpul MLOK VFG

Lower:

LMT Def2K ergo grip with enhanced Sopmod
Geissele SSA
JP Enterprises Spring and H2 buffer
Magpul enhanced trigger guard
VTAC 2pt padded sling

I really like it.  I don’t trust it to the same level as my T2 yet but on the whole it has been great, with features my T2 can’t touch.  Seems to have more parallax than my T2.

thanks, gonna check some YT reviews.

the 14.5 isnt a go to rifle and the optic budget is like $400ish or is just t2 all the things lol

Sometimes it's hard to refute the "T2 all the things" argument.

And I love LPVOs and high mounts.

Agreed, I have four that replaced all my T1's.  It's a better micro rendition in every facet.

I had one LPVO but I rarely used it as the weight vs the T2 was challenging on 8-10 hour hunts on foot.

If I'm adding 1+ lbs of optic, it's giving me super powers:

@SurtrsFire

Check out this video John Lovell put out recently, where he digs into the holosun elite line:

I committed to the bit and now I have three 1-6 razors.  You notice the boat anchor weight less when you always have it on there across multiple weapons.

Yes, if it's normalized across multiple platforms I can see it being unnoticed.  Back and forth between a T2 and it was not nice.  Granted it was two different IR/NOD setups, so I'm lugging the variable optic with an IR laser vs one with a T2 and IR.  At night the LPVO is only a big anchor and of no use...

Whats everyones thoughts on say a T2 vs one of the Comp models that take AA/AAA? I see the T2 is lighter, but is the battery commonality of the Comp series worth the trade off?

Im currently stuck on deciding on a TA31/33 or a T2/Comp? for a go-to LT UU 12" 5.56 I have coming

ETA: my current go-to is a 12.3" BA Hanson, Aero M4E1 receivers. LT Slick-AR 11" and MBT with a Holosun 503 circle-dot on a G mount. It was originally a "fun" build that I had the receiver sets cerakoted tungsten, but it came together so well, I put it to go-to role. I like the circle-dot of the HS optic, so if I went with an ACOG it would be the horseshoe reticle.

A few thoughts:

- The T2 is lighter and a little shorter, the latter variable will give the slight appearance of less tube effect looking through it
- The M5 is 7075 with the T2 being 6061 aluminum; the former is more durable in theory
- ...however, there is a test by pew pew tactical [0] where the CompM5 bowed early due to the battery compartment breaking on the drop test
- The M5 disconnected switch design (in theory) allows it to run when damaged in ways a T1/T2 may fail (never seen this actually happen but it's a talking point with M4/M4S fanboys)
- Many M5 users have seen issues with the early M5's.  Dot won't turn on etc.   Not certain if it was an early run issue or what the main problem is/was

Personally, I have owned five T1's and now have four T2's.  The T2 lens and body improvements make it much better than the T1.  

I have little interest in the M5 variant.  The AAA batteries are not a selling point for me, and I like the overall form factor of the T2.

Aimpoint overall is very GTG.  I think ACOGs are good for what they are.  On an SBR I'd probably go with the TA44 or TA33 for the eye relief and overall size...

ETA: If Aimpoint can make a 25mm "micro" and keep the price decent (ain't happening) with immaterial parallax (think T2 results vs T1 and MRO) it would grab my interest.

Just signed up here mine as well drop a picture

It's a PWS mk111 mod1 upper ........ can is still jail

Just bought my first pair of nods from the EE so the set up will change soon to accommodate








Hmmm shows it as an image when I click preview????

@StarCityShooter
I have 3 T2s and 2 Comp M5s.  The T2 is a little lighter than a Comp, especially M4s.  I do not have experience with Comp M4s, but I am pretty sure the M5 out preforms the M4 in about every way.  The only real difference is the AAA Battery.  

For me, they are about the same.  I run Comps for the same reason they were made in the first place.  Just because the batteries are always available.  In a grab and go situation, I like only having to worry about 3 types of batteries instead of 4.  In my case,  everything works on 123As, AA & AAA.  That covers NODS, IR, WMLs & Optics.  

In a pinch, I grab a vest, helmet and gun.  I'm ready to train...

@DefenderAO
Man, every time I see that thing I can't believe I don't have one!  Really nice optic...

Thanks.  They are quite impressive.  The hogs around here sure do hate it though

Waiting for my Triarc 12.5" upper and OSS titanium can to get in as the new home for it.  

The go-to now has appropriate desert camouflage.

looks good....other than the plastic DD ejection port cover

Weirdly the ejection port cover hasn’t caused any malfunctions. Think I’ll keep it.

you never know...

My trusty Colt M4 with TA31RCO is the 'go to'. Even though its a dated design it always goes bang and never lets me down.

still one of the best looking ar15 configurations ever

It might be dated or there maybe other options that are lighter or better for in close. But for an all around rifle that’s hard to beat, and you know it’s going to go bang. The 6920 is the rifle all others are measure against.

I should also note that I use the scalar works mount to swap it on onto a 15-22 to train with, so the weight is present there also.

@TBone556
This is true.  It's just too bad Colt completely stopped all R&D after they made that gun.  IMHO, Colt has done almost nothing to advance the M4 platform in 15 years.  

There are so many great AR companies out there that have made major improvements to the Platform.  I just don't understand why Colt was not at the for front of these changes.  I would like to say I'm a Colt fan boy,  but I've only ever found use for their barrels, and that is only when a Clone requires a Colt Barrel....
