View Full Version : Long Range 16" Build
I wanted to learn distance shooting, and my CL 14.5" barrel wasnt giving me the results I needed.
I have weekly access to a 700yd range with 1000yds available once a month or so. I built the following to push the limits of a 16" 223/5.56 and develop my LR skills.
Tip-to-butt:
FCD brake
Harris hbrs with badger mlok adapter
Larue Stealth 16"
Giessele Mk8 15"
Aero upper
Bcm bcg
Bcm mod4
Anvil arms lower
Bcm gf3 grip
Larue MTB
Reptilla AUS
Brownells MPO 3-18
Arrendondo magwell
B5 bravo

Called flier opens the group to 1.5"
Shot with bang bag and bipod off wooden bench. I believe the higher shots are something Im doing. Still learning:

I was TODAY years old when I found out that the words Long Range & 16" could be used in the same sentence.
Brother thats fine shooting right there, NICE rig. What ammo?

Haha, yeah... im using the term in a 223 context.
69gr handloads. Ill be trying these and also working up some 75s for 1k.
Very nice looking carbine.
I find I shoot better from a bag or back pack than with bipod, just if you haven’t tried it.

Thanks, ill try it. Im definately doing something wrong. I was messing with trigger pulls and bipod tension (how hard the stock is in my shoulder), and it moves my poi up and down. The three high shots were "looser".
I should be on the 700yd tomorrow.
Very nice. Flyers or not, those are good real world results. I look forward to seeing your work with this build.
Most impressive, thank you for the specs noted, may adapt and try a new build to start doing distance shooting as well.
Had a great day. Had repeatable hits out to 650 on c-zone (5 in a row). Followed with a first-attempt hit on a 4" plate at 600. (First round on that target, but had windage from 550 &650). Not super repeatable, but a good confidence boost.
I'm going to work this load and try new primers and boosting the charge. It cycles but does not lock back on empty mag (69gr x 2725fps). Im getting random, unexplainable shots around .3 mil off, always seems to be high/left. Trying to determine if its me or the load.
Almost forgot, dude I met had a USO 6-36x(iirc), very nice. My scope absolutely works at these distances, and I love the reticle, but i see where the 3x price goes... clarity was noticably better, and no noticable chromatic abarration. The brownells has blatent abbaration on 18x but the reticle is crisp and tracks very well. Image is clear enough to see what I need to at 700. The image clears up a bit just dropping down to 15x. He also showed me up with his 20" AR on the headhunter... time to put more work in!

Well that’s a good time. Well done!

You shot that group at 700 yards?
If so, holy crap dude, that’s awesome!

That's a hundo group. If he shot that at 700 yards, I'd quit shooting.

That’s your 100 yard group?
YOU SUCK!
Just kidding!

Lol. I do though! See below, i feel like this is a 1" gun easy, might have to get some fgmm to rule out or confirm ammo.
Any idea whats going on here? Got my velocity SD down to <12
Is this a trigger press/followthrough issue? Could inconsistent stock pressure/placement do this? Parrellax was correct. I keep getting 2 distinct groups:
1- 6 shots about .8"
2- 4 shots i. .7"
3- 5~1.1 (top shot was cold bore)
4 - 5 shots in .46"

I would get some good, solid match ammo, setup a bipod and rear bag, and take your time shooting.
It took me a long time to get anywhere near the groups i get now. I started in to the long rang PRS not too long ago (getting out of it now). It took me about a year to hold a 1” 10 round group with match ammo that costs 2.50 a round.

Put a harmonic balancer on the end of the barrel, see if that closes up the groups. If that works then you might need a different barrel.
I’ve had some Larue barrels shoot lights out and some just ok. They all needed a little break in though.
Ditch the bipod, get good sand bags fore and aft.
69s will go trans-sonic between 800 and 900 yards. You'll need a heavier bullet to stay supersonic at 1,000 (typically a Sierra, Berger, Hornady, or Nosler -- 70+ Very Low Drag, or an 80 / 80+ grain Match, usually loaded long for single-shot feeding).

Gun looks great.
I have a similar "long range-ish" 16" I setup for the same purpose. Groups a bit over 1.5" using regular old XM193 and a DD CL/HF barrel.
Eventually I'll get another scope, but it's low on my priority list and already groups better than I thought it would.
Also recently installed a Larue two-stage and a couple hundred rounds of "match" ammo (77g?) so I'd like to see if I can tighten it up.

I'll try this to better evaluate the gun itself.
I do have some nossler cc 77 and rmr 75s, just loading up the rest of my 69s right now as most of the shooting is 700 and in.
Ive been pretty consistent making 1st round hits on 2/3 ipsc at 650yds... so im pretty happy with it so far.
Sure nothing wrong with “ consistent making 1st round hits on 2/3 ipsc at 650yds...”
Around here that’d be something to be really happy with, given our winds and running a .223/5.56 AR.
That's a hundo group. If he shot that at 700 yards, I'd quit shooting.
Ha! Yeah, you and probably everyone else here.

Yeah that's outstanding.
I'll likely post more load details in the reloading forum
Got the tac dialed in for RMR 69s
2800fps
Mostly vertical stringing and even federal primers had high SD. I hand measured each load and all same batch of brass.
Overall happy with it, i shot off a pack and first time out in a while so think this is a 1moa gun but im influencing it... and I need some decent ****ing primers!!
This will accomplish what I'm looking for.
The 2 velocities written are the 2 highest of the string. Without those, the spread drops to 44 and SD to 15.

This is nice. I will echo what others have said regarding getting and using a front bag and a rear bag. I will also add that I would look at the B5 Systems precision stock or the Magpul PRS and PRS Lite stocks.. These are all fully adjustable and can help take some of the variability out in your cheek weld and eye relief, as well as add a little weight to the rear of the gun.

Yeah I need the weight. Ill probably buy a good bag for prs , and plan on getting the XLR/Dissident stock.
Just waiting for a sale.

I've had stuff like that lately too. Even with ammo loaded on the Chargemaster and Wolf primers. Just some oddball velocities that wreck my SD.
I shot some WIN M855 retail box that had better SDs than hand loads.

Maybe I should make some mexican match and see what happens?
I try not to sweat SDs too much, but when they're in the 20s or more off the chargemaster, it's a little annoying.
Ok so to wrap this thread up, I finally got this out to 1k.
Steady 5mph winds with gusts to 12-15.
Tac, rmr75 going 2630fps
It took a while to get on at 850 (no calls) but once we saw impacts in the dirt, I walked in a hit at 850, then 930 after a couple more shots (2/3 ipsc sized steel).
We switched shooters, I spotted my friend on the same targets, then he connected at 1k (tac & rmr 69)
[He has a near identical build: same scope, but a 16" rainier UM, aero handguard that bolts directly to the upper.]
Once I got back on the rifle, I dialed 14 mils, the wind had calmed a little, (i think I was holding 1.75mil windage) and I connected at 1k on shots 5 and 6.
My first time hitting 1k, I'm very excited!

Anyone who says 223/5.56 isn’t good past 300 yards doesn’t actually spend time behind their rifle. I’ve been running my 14.5 with 2-10 Credo and 55gr freedom and pmc xtac to 600 easily. Granted I’m not going for precision groups just accurate repeatable “combat accurate” hits using “commonly available” ammunition types.
I’ve got my own private range I can get to 1085 yards on and targets at random distances from 208-626 then 800 and 1008. It’s setup more as a “dynamic” range for everything outside the 200 yard flat range.

This. 300 yards is nothing.

If there's such a think as "range envy", I've got range envy. You have a very nice place to shoot sir!

YMH R9 came in.
I also upgraded the stock due to lack of cheek weld. Its the dissident arms stock.

That is a good looking gun man, I like the camo, simple but effective. How do you like the Brownell's 3-18x? I have a M&P10 rocking an old 4-14x Primary Arms scope that I think I snagged for $180 with other parts in an Armslist trade and it just doesn't cut it any more

Thanks - Im loving this rifle!
The camo used maple leaves, mesh, and some random tape pieces to break up the colors
I think the scope is really good for the money.
Ive had it out to 1kyds no issues, CA is noticable but mild.
Eye box is very tight at 18x with some edge distortion
Clarity is not as good as a leupold mk5, but again - perfectly usable to 1k
Its heavy
Tracking has been repeatable
Great tectile and audible clicks
Great reticle in the mid to higher zoom ranges. Its kind of thin 3-5x. Usable there, but its not the quickest to pick up at speed. Above 6x its really nice.
