I am in the process of building a SBR in 300 Blackout. It will have a 10 1/2" Barrel. I am going circles trying to decide on a scope. The gun will be for target shooting, hogs varmits ect.

Optics Budget Max is $1500 but really would like to spend the money saved towards a suppressor for the 300. I already held out $400 for the 2 Tax Stamps so I still have $1500 to play with. I prefer to get optics and have some left for a nice one piece QD Mount that will hold zero. Last requirement CLEAR Glass I am tired of low end scopes this rifle deserves decent respectable optics. So here are the choices I am leaning towards however I am NOT set on these and would appreciate any feedback or suggestions. 

Some of the optics I have considered are:

Leupold 1.5-4 VX-R Patrol (Have not seen how clear glass is, cant find one locally to try) (Kit has 1pc Mount just not QD Like I wanted)

Burris Xtreme XTR-14 (Have not seen how clear glass is, cant find one locally to try) (This is nice as it has Fastfire 3 reddot included)

Vortex Viper PST

Another 2 I consider but will eat up my budget is the ACOG for .300 Blackout and The Browe Both will eat my budget I have set aside and will limit me getting a can right now. I know I can get a can with a rebate or discount for $600 so that would only leave $900 for optics including QD Mount.......

Ok hope I painted a informative picture of my budget and requirements looking forward to suggestions. Even if the optics suggested is not on the list.

Welcome to Optics Talk. 

I'm an advocate for the VX-R. I have one in 3-9x with the Firedot Duplex reticle and I think it works very well in low light hunting applications and for target shooting. I've shot some darn fine groups with my .223 Remington.  
I haven't fooled with the 1.5-4x, but I would definitely consider it. Glass quality is "pretty good" and online with the others you've mentioned, I'd say. The real benefit to me is the Firedot reticle on the Leupold.  

If at first you don't secede...try..try again.

If u plan on shooting subsonic and want to shoot very far, you will want a scope with target type turrets and alot of elevation travel. I habe the vxr partol 3-9x. I like it, glass is good and the illumination is awesome. But it does not have enough elevation adjustment. So eventually i will get something else. The ss 1-4x or 1-6x would be a pretty good choice as they have alot more and they also have better glass than the vxr line.

Lifetime warranty and excellent customer service don't mean a thing when your gun fails during a zombie attack.

FFP with lots of drop on the reticle, like an IOR 2.5-10.

A 10.5 will be loud, even suppressed

Nikon has developed the all-new M-300 BLK riflescope to maximize the
effectiveness of the .300 AAC Blackout cartridge while using both supersonic and
subsonic ammunition. Now, shooters have a 30mm body riflescope that can harness
both variations of this up-and-coming cartridge.

Welcome to the OT.

X2 for the Nikon although I have two of the vx-r's and they are a lot of scope for the money. Frankly I feel like the glass in the Nikon is somewhat superior to the Lupold offering though, the M-series and P series Nikon scopes offer a lot of quality glass for the money.

I just added the M-series Nikon with the laser rangefinder built in with though barrel yardage reading. I have yet to get it afield but am very excited for what it will do for me on fast moving targets with mainly varminting in mind.

I'm not sure if they make this scope system with the appropriate cam system for the blackout but if they do it would be a great choice as it falls within your budget and offers a lot of glass and more for the money.

I will be interested in seeing what all is recommended to you on your string simply due to the fact that I have a blackout on order that is configured to match a Yankee Hill phantom 2 suppresser as well. At this point in the 300 configuration that our fellow member recommended above is first on my list for my personal consideration.

Good luck and keep us posted, REP

I am currently testing that Nikon scope and I have a bit of a mixed feeling on the reticle so far.  Otherwise, it is a decent scope.

Honestly, if I were scoping a Blackout, I would be looking at something with a FFP reticle that has a lot of holdover marks.

If you are OK with a slightly larger scope SWFA SS 3-9x42 is my current scope of choice for this rifle.  I just built a Blackout for my brother and that is the scope he is going to have.

Among the lower magnification scopes, I would stick with something that tops out at no less than 6x.  SWFA SS 1-6x24 is a decent option, although for the Blackout I prefer more holdover points.  I've used the 1-6x24 SS on a Blackout and it worked well, but I ultimately thought it was a better fit for my 458SOCOM and that is where it lives.

With second focal plane scopes, I would probably get the Leupold VX-6 Multigun scope.  I am not a huge fan of the SPR reticle for many of the applications, but for the Blackout it works well, I think. -

I've had no luck with calibrated reticles, prefer mil with data table. But maybe it's just me.

Generally, I fully agree with you and for twisting turrets, I would stick with SWFA SS 1-6x24 for this application.

However, the Blackout is a lot of fun to shoot a bit further out with subsonic loads which, for the most part are defined by these two qualities:
1) They are not very accurate
2) They have a lot of drop

Interestingly, they do not have all that much wind drift, so holdover works well with them and the inherent in inaccuracy of holding over is sorta within the inaccuracy of the round.

I am really leaning towards one of these 3 the SWFA's are First Focal plane and Burris Dual Focal Plane. Any suggestions on these options. They all are eating a lot out of my SBR Build budget but don't want to skimp on the optics too much. I am thinking the 1-4 SWFA I might as well just get the 1-6 and be done if I go the swfa route. I cant seem to find any reviews on the Burris XTR 2 series in this model I guess its too new or I can work google good enough..... -

I'm a fan of more magnification in a subsonic round.  A 1-6X would be the bottom of what I would consider.  My 300s usually wear a 2-10 or 3-9.

My favorite 300BLK scope was a 2.5-10 IOR with their MP8 reticle, it had LOTS of drop on the reticle and is a good mag range for the caliber.

I've tried about 10+ different scopes on my 8" blackout (sub shooting only now) 
Just a few notables -
Browe, - , sucked royally terrible experience with Browe, not sure how they are still in business with their business model.
Nikon - - , good scope, worked better on the 16" upper I had than the 8" SBR. For the price, hard to beat. Fairly close drops on the reticle.
ACOG - - http://swfa.c - om/Trijicon-3x30-Acog-Rifle-Scope-P12905.aspx , worked ok but didn't have the magnification that you need when shooting subs like RC mentions.  If dedicated to shooting supersonic (which should be the case without a suppressor) it would be fine.
Optisan - , just for giggles while in between choices I tried it on there.  Worked fine but took some time to really get a good understanding on the adjustments for viable use
Mark AR - - ,   what I have on there right now.  Still need more magnification but waiting on SWFA's next release, hoping for a 2-10. 
I would like to try the smaller 2-10's out there, IOR, Nightforce, Vortex, etc.  I think for a sub only gun it would be the most practical

Downside to the Nightforce 2-10 is that it is SFP, so only calibrated at 10X.  Don't get me wrong, I have the 2-10x42 on a 308 AR, great scope, but not best, in my opinion, for a caliber with LOTS of drop and may need to take close shots (where 10X is very restrictive.)

8 mils on the reticle isn't bad.

I was asked about my statement that my Nightforce only ranged (accurately) at a specific setting.  I consulted the NF MOA reticle document (here: it confirms that ranging is only accurately accomplished at a single power setting.  It is possible to range at other powers, using some mathemagic; however, scope makers do not (to my limited knowledge) calibrate the mag range anywhere but one point, maybe 2.  Other numbers on the range are approximations.

Hope that helps.
