Variable power optics on 9" 300BO SBR?

[ARCHIVED THREAD] - Variable power optics on 9" 300BO SBR?

Posted: 1/17/2017 12:41:39 AM EDT

I've got a 9" 300BO SBR I currently run irons on but am considering a variable power scope. I have been looking at the Primary Arms 1-6x ACSS 300BO/7.62x39 optic since I have one of their ACSS optics already.
I originally built it as a PDW but I have started using it to take some deer the last two seasons, yes it is suppressed and I primarily use super sonic loads.

Anybody that's running a variable power optic on their 300BO SBR chime in.

I'm also thinking about that optic in the same application, be curious to see the responses.

I built an 8.5" with adj gas and side-charging upper, will be suppressed all of the time.

I just put a Primary 1-6 300blk on my 8" and I'm in love with it. I bought it for a pig hunt coming up and couldn't be more pleased, though I have only had one range trip with it. It replaced a EoTech holo/magnifier which I thoroughly enjoyed.

It's a little fishy at 1x but the reticle is daylight bright. Glass is surprisingly good for the price. It's easy to quickly get on target. I can post up some pictures if you want. If you're interested in doing it, I can tell you that you won't be disappointed.

Couple more thoughts...

The reticle is kind of small, but my aging eyes were able to pretty quickly use the subtensions out to 100 yards with subs and supers.

I haven't checked the MV on the factory loads but I'm assuming I'm a little on the slow side for what the reticle was calibrated for. After I figured out what lines to use it was fast getting lead on target.

The zoom ring and all the other adjustments are smooth. A whole lot of scope for the money. My only concern is longevity but for the money, even a few years of use is well worth the coin.

I thought it might be overkill getting a variable zoom for a 300 shorty but I honestly feel like it's a jack of all trades now. I feel comfortable using it for home defense, target shooting and a game gun.

I have a 10.3" 300 BLK AR-15 SBR.

I started out with a RDS, but wanted more versatility (I plan to hunt with it), and went with a Vortex Strike Eagle 1-6.

As far as I'm concerned, it has worked out very well. It's a nice clear scope, and while it has a bullet drop reticle geared for a 5.56, I was able to figure out the correct marking for 50, 100 & 150 yards with sub-sonic ammo easily.

Hope this helps,
Bob S.

I run a Millet DMS 1x4x24 on a 9in sbr. It works good for as far as the gun can shoot. One kill at 265 yds.

Will do, it'll be tomorrow sometime but I'll get some up. I have a 7" can that's always mounted so the overall length is about standard. I'll take a picture without the can for effect.

Got an 8" 300 blk pistol now, waiting for approval to slap on a PDW stock. I'm up in the air on what sight to get. I love the idea of variable power, but in wanting to keep this AR small those variable sights look to add some bulk. Was leaning towards the Vortex strike eagle for a bit but now I'm thinking of maybe a regular Eotech to keep everything small.

Similar boat, 9.5" blackout with an aimpoint t1

I'm looking at either a Accupoint or Accupower, both 1-4. Just trying to keep the gun light.

I currently have a RMR 3.25 moa red dot on my 8" 300 blk, I'm going to try out my Vortesx Viper pst 1-4 and Steiner p4xi this weekend to see how I like it and which reticle works better for supers and subs. I would like to get a Leupold 1-4 but they don't have a true 1x and a reticle I like with small 2 moa increments.

Took awhile but here you go. Can't get out to show zoomed glass quality and daylight bright reticle, but you can see its pretty bright. Yes I'm a messy reloader.

Its just a Vortex Crossfire 1-4 with the illuminated reticle (the V-Brite I think it is called) I Like it a lot for the money. With the illuminated reticle and at 1x it works good up close and at 4x it's very serviceable at distance.

I have a 3x9x40 vxr patrol on my 300 BLK SBR which has a 9" barrel; so far it has been deadly accurate, sub 1.5 MOA with Hornady and Barnes ammo!

I use the same scope on my 10.5" 300blk using 205 grain subs. The reticle lines up pretty well with that load and barrel combo. It's a good scope for the gun just be sure to check your muzzle velocity and use a ballistics calculator to true your reticle and load up, maybe make a reference card to go with it and you should be good to go. The illuminated reticle is nice for hunting also.

I use a vortex PST 1-4x in a low NightForce Unimount on my 9" blackout. Nice glass for the price, but unlike my PST 6-24 that I use on a target gun, the reticle on the 1-4 is a little too small for my taste. For a run and gun at 1x it's adequate but no more. Trying to use the reticle for holdovers when going between supers and subs is nearly impossible; I just dial. The zero stop does come in handy then.

My other complaint is weight. The PST does feel top heavy, even with the lightweight NF mount. However, the field of view is leagues better than the featherweight Weaver 1-3x on the .22 SBR, so I feel the trade off is worth it.

If I ran supers exclusively for hunting, I might opt for a low magnification fixed power scope. If I ran only supers, I think I'd go Aimpoint.

At least you're in the basement, my reloading setup is in my shop which is just heated enough to keep the water from freezing and no A/C. Nice looking SBR

I use an SWFA 1-6 on my 10.5" blk. I like that it gives me 20 extra mils in the reticle for shooting subs at range. That gives me over 37 mils of elevation between the reticle and the turret.

Put a Leupold vxr patrol 1-4 on my 300 blk pistol thats waiting to be an sbr. 1-4 or 1-6 is great for a do-all/general purpose type rifle imo.

I think a 9" barrel would match well with a Vortex Viper 1-4x

I know have an eight month wait to figure out what optics to put on my Angstadt Arms UDP9 PDW SBR!

I could use my AAC Evo 9 can but I might end up with something new to go on it as well.

Here is what a Bushnell 1-6.5x on my 9" 300BLK should look like. I am still waiting on a mount since I spent $3K on optics this week

Something funny that I noticed is that the battery cap and internals are exactly the same between them.

Yeah I went a little crazy and also bought a Bushnell LRTSi 3-12x44mm. I did sell an ACOG and an Aimpoint though to help offset the expenditures.

I have a very understanding wife

I use my 8" 300 blackout for deer as well with an SAS Reaper suppressor. I've found that the Steiner P4xi 1-4x works great: good eye relief, clear glass, and daylight illumination if you want to use it for home defense and run it like a red dot.

For comparison, I run a PA 1-6x ACSS on my 16" 5.56 rifle and the Steiner blows it away for clarity and eye relief.

Edit: shooting Barnes 110 grain Vortx ammo, you can use the first hash mark as a BDC for 200 yards with a 100 yard zero.

(Top rifle) My 8" 300BLK w/suppressor wears a Lucid L7 (1-6X24). Works great for hunting. Slightly heavy for just playing around all day.
I also have the PA 1-6 with ACSS on a 16" rifle. Great optic.

I run a PRO on my 10" but wanted a variable power for hunting. I got this Leupold Mark4 MR/T 1.5x5 with the .300BO reticle on it now. I've only had a chance to sight in at 100yds in prep for a hunt last month. I haven't had time since to really check out all the settings or shoot out to where it's marked up for. It's my first FFP scope but I'm liking it so far.

funny, i read the title and was jumping in to say "variables would be dumb on an SBR unless you're hunting..."

That said, I put a Trijicon 1-4 on my 10" HD rifle for a while. I have one on my competition rifle and it's great for anything inside contact distance to 450+ for me. But it was a lot of bulk and I was never going to use it zoomed in, so I switched to a dot. I am currently building a PDW style 7.5" 300BO and it's sole purpose will be inside the house/yard so again going with a dot.

a true 1x on the low power makes a huge difference. I've had good luck with Trijicon and the bushnell 1-6, along with swarofski if you're feeling spendy have all been great on the low power end. I hear great things about the PA, too, so I wouldn't hesitate to go with it.

After Form 1'ing my Sig pm400 elite 8.5" AR pistol, I immediately got PA's 1-6 ACSS and really liked it, but the rifle felt chunky and heavier, particularly with my Sig Titanium direct thread 308 suppressor. Made swapping between subs and supers simple, and my eyes need the magnification at 100 yds and out (to shoot moa).

I removed the PA 1-6 x ACSS right away

(EE, soon) and got a Leupold Deltapoint Pro with 7 moa triangle instead. I can adjust for elevation between subs and supers, but primarily shoot suppressed subs anyway. Think "pellet gun and a thud" as subs impact dirt at 100 yds. Its a beautiful thing!

If I ever get magnification for a light weight sbr again, it'll be the smallest and lightest 1-4x available, which doesn't include a Trij Accupoint that's' already in my safe, unfortunately.

Posted: 4/9/2017 11:29:21 AM EDT

[#43]

While not a true 1x, the Leupold VX-R 1.25-4x is just about the lightest 30mm "tactical" scope I know of, lighter than most by four or five ounces. Leupold quotes it at 11.5 ounces. (I like mine, although I wish it had a dial for power vice the button press method.)
