8. What modifications and additions were done to my MR762 during my 2nd class?
After the first class and after seeing HKPro member Nsheers’ MR762 12” Assaulter build, I decided to build a similar MR762 SBR.
A. SureFire Flash Hider QD. No change. I switched to a SureFire Muzzle Brake, which is a disaster. Will detail later on
B. SureFire SOCOM762-RC suppressor. NEW. Stupid me should have kept the Mini; got excited with BATF approving the RC
C. Harris bipod. NEW
D. Bushnell ERS 3.5-21x50 scope. 34mm with FFP, Zero-stop and Tremor 2 reticle. No change
E. LaRue Optics QD mount. No change
F. Accuracy 1st leveler. No change
G. Aimpoint T-2 Micro RDS. NEW
H. RDS attachment. Can’t recall what I bought
I. Geissele HK417 trigger. No change
J. Blue Fore Gear front sling attachment. No change.
K. Blue Force Gear 2-point sling. No change
L. G28 buffer tube. NEW
M. G28 buttstock. NEW
Given my MR762 13” Assaulter build is meant to be compact, I will dedicate my SureFire SOCOM762-Mini to this carbine. I will leave the full length SureFire SOCOM762-RC suppressor to my second MR762 that is 16.5”.
I am indifferent between Harris bipod and Atlas bipod. Everybody seems to love the Harris. I really can’t tell the difference. : (
9. What questions did I struggle with?
I can honestly say that the only thing I struggled with is barrel length.
I struggled with 12” vs. 13” barrel length. Original HK417 Assaulter was 12” with the new HK417 Assaulter 13” (just like the new HK416 shorty is 11” length instead of the previous 10.4” length).
I decide on the 13” because loss of muzzle velocity accelerate as the barrel gets shorter. I hear rumblings that the 12” will not cycle properly without a suppressor, but I have yet to shoot without a suppressor.
I will test out the MR762 13” Assaulter build the next time I go to the gun range and report back.
Hopefully the 13” will cycle properly without a suppressor. Otherwise I might have to test out a 14” MR762. Yucks… That would suck…
10. What steps are involved in building a MR762 SBR?
Not very complicated actually
A. Apply for SBR permit. Takes about 4 to 6 weeks with eFile
B. Send lower to get engraved. Takes about 4 weeks depending on how backed-up the engraver/machinist is
- IIRC, your gunsmith has to ship the lower back to your FFL.
- It was a PITA to take apart the lower, but thankfully my gunsmith/FFL took it apart before shipping to the engraver
C. Decide on what barrel length you want
D. Send upper to machinist to get barrel shortened
Once everything is done, you need to put together everything again. Not a huge hassle, but then again not a 5-minute exercise.
11. How did the MR762 13” Assaulter perform?
It performed beyond my expectations. I was able to shoot out to 1,000 yards consistently. Was making 50% to 60% of my 1,000 yard shots.
I didn’t shoot 2 or 3 times and assume I would make 50% to 60% of my shots. I literally took my time and attempted 10 shots in a row. My buddy was counting off the hits.
Once the elevation was dialed-in and the wind was blowing consistently, it was simply a matter of consistent shooting techniques including making sure the carbine was level.
I won’t lie in that my mind was blown. Can you imagine? A 13” SBR able to shoot out to 1,000 yards in the hands of a novice like me. I can easily see a skilled sniper making 1,200 yards to 1,500 yards cold bore first-round hits. #MINDOFFICIALLYBLOWN
Towards the end of the class, after I was packed-up and ready to go home, Todd asked me to shoot one more time while he observed me. I was already stoked that I could make 1,000 yard shots consistently that I didn’t want to end my class on a down note in case I missed badly, but I said what the heck.
The farthest I had shot was 968M according to my laser range finder (975M according to Todd). Todd pointed out a target at 1,505M. For those of you counting, 1,600M is one mile. 1,505M was waaaaaaaay farther than anything I have every shot at in my life.
With a bunch of other students standing around to observe me shoot, talk about pressure!!
I looked at my Kestrel, and stupid me read 29MILs elevation which I later realized was wrong. I dialed my turret to 10MIL, which means I had to hold 19MIL for elevation in the reticle (29MIL less 10MIL turret hold). Todd made the wind call, and after taking a very short time to get into a comfortable body position, I checked my leveler and focused on my grip. Fingertips on the grip and thumb outside so that I wouldn’t accidentally torque the carbine, I took a few breadths and then checked my leveler one last time.
After slowly exhaling, I slowly and calmly sent a round down range (Todd was constantly calling out the wind read every 5 seconds or so, which meant the wind call was pretty accurate vs. 30 second dated).
Todd told me to adjust my elevation 5 MIL, which was crazy. I completely missed my shot.
Second shot was pretty damn close.
Long story short, I made my shot on my 3rd attempt. What an awesome feeling!
Granted it was a huge target since I couldn’t see squat with the scope zoomed out to read 19MIL. That is why I am actively looking for an ammo that has higher muzzle velocity, higher BC (which means better aerodynamics) and together tolerances in terms of MV spread. Due to my slow muzzle velocity, I had to hold a much higher elevation (34MIL vs. my buddy had to hold 29MIL for his 16.5” ORB using the same ammo). That meant I had to zoom out to 15x??, which is hard to make out a bus at 1,505M let alone a human target.
After I made my shot, I took a look at my Kestrel to figure out what went wrong. Stupid me was reading the elevation hold for a shorter distance (1,300M or 1,400M I can’t quite recall). The Kestrel was actually correct at 34MIL hold. Not sure why I read 29MIL hold
If I had read my Kestrel correctly… If my shooting didn’t suck… If I had faster ammo… My buddy told me to keep my excuses to myself. : )
Bottom line, the MR762 13” SBR is pretty damn amazing. Short enough to bring into a vehicle or chopper and short enough for CQB work (although a 308 round will probably pass through walls so maybe not ideal in that sense). Yet able to reach out to 1,000 yards easily and consistently; If I can do it, pretty much anybody can do it.
I hope all you HKPro members with the MR762 exercise the heck of of your MR762s. They are capable of making 1,200M shots easily. Go shoot them!!
12. What was the best part about the class?
I was going to say the best part of the class was making back-to back shots in at 1,000 yards. That was a freaking awesome feeling. Watching the target move and hearing the sound of metal on steel gave me a pretty darn natural high.
However, and in all honesty, the best part of the 2-day class is hands-down the vid of my buddy settling down and getting ready to make a 1,000 yards shot halfway through the second day.
First pull, and he rang steel! What a glorious feeling.
My buddy had never shot more than 200M in his life. After 2 days of tutelage under Todd, he was able to make a 1,000 yard first round hit the second day. Granted he was using Todd’s LaRue OBR 16” that was completely dialed in and with an amazing NightForce scope. But holy kow. 1,000 yards!
I can't show the vid for a variety of reasons, but it shows me taking a second to register that metallic "ringing steel" sound. I turned around to look at my buddy and asked in a completely dumb-founded manner "Was that you?!" My buddy, who is a very calm dude and totally oppose of easily-excitable me, said in a matter-of-fact voice "Yep. That was me".
I lost it there and then! The other students looked at me funny when I started laughing like a lunatic.
The only reason we have a vid is because Todd’s son was nice enough to take a pic. I passed him my phone to take a few pics, and he decided to shoot a vid in addition to shooting pics. I can’t believe my buddy has a vid recording of making a 1st round hit at 1,000 yards. So freaking jealous!!
13. What tweaks if any would I make after the class
Without getting into too many details, I would make tweaks to the below. I learned a lot from my class, and there are tweaks to my gear that I wish to make. I also want to shoot long distance more regularly so I get enough practice.
14. What does one need to bring to the class?
Nothing. Just an open mind and a willingness to learn.
Literally, Todd will provide everything including the LaRue OBR carbine with NightForce scope, Kestrel, laser range finder, spotting scope, shooting matt and even ammo.
If you can show-up at his class, he can provide every single thing. Personally, I prefer to shoot with my own gear. However, if you want to “kick the tires” before buying any gear, you can show-up empty handed.
Just make sure you coordinate with Todd in advance.
I clarified a lot of stuff in advance of my first class so I showed-up with lots of gear that Todd recommended (with no financial incentive on his part). It felt good to shoot with my own “stuff”.
15. What did I bring to the recent High Angle Long Distance shooting class
Probably makes more sense if I described my kit/gear at my first class.
No Kestrel and no laser range finder. Which is totally fine as I didn’t want to buy the wrong gear and be stuck with it. I attended my 1st class with specific question as to what I should buy (best value for money obviously) so that I could avoid junk gear.
Unfortunately, I showed-up with crappy XM80C ammo.
I think the only good thing I had going for me was the MR762 16.5” and a shooting pad. That was pretty much it
For my second class, I came with pretty much everything including my own Kestrel, own laser range finder, etc. I wanted to know my gear inside out. I won’t lie in that the Kestrel confuses the heck out of me. Then again, I was never the sharpest knife in the drawer…
16. What did I learn?
There are so many useful things that I learned from the class. To summarize what I learned in 2 days into a few paragraphs would be a massive disservice to all of you.
The two most important things I learned about long distance shooting are:
A. Three common mistakes that all long distance shooters make.
- The number 1 issue, which I did not expect was rifle cant.
- Bottom line, get a leveler. Even a crappy one is better than none
- The other 2 common mistakes, you guys should learn from Accuracy 1st or other sniper instructors
B. Learn how to shoot with the 308 as it makes one a better shooter
The 308 is pretty darn unforgiving when it comes to making bad wind calls.
So learn how to shoot with the 308 caliber.
And when it comes to SHTF situation, shoot with a caliber that is less affected by poor wind calls, easy to acquire rounds, easy to acquire spare parts, etc.
And the answer is… Take a class with Accuracy 1st or any long distance shooting outfit. Hahahahahahaha.
Hope the above was helpful. Please feel free to ask any questions. I learned so much from the HKPro community so anyway I can contribute back will be awesome.
Pics to follow. Will post the same write-up on RelakJoe.com. Only difference is that it will have a ton more pictures. For all you gun porn addicts… : )
