Sorry if this is a dead horse topic, but I've been trying to find the best optic for my 300 blk 9" SBR with can (waiting on stamp for both). It's a 9" AAC 300 with SDN-6.

I've spent weeks researching the topic (particularly this site), but I'm still unsure.

I plan on shooting factory subs close to 100% of the time. Very limited supers...maybe hand load subs in the future, but nothing in the works.

Primary uses are plinking, HD, and varmint eradication (hogs, skunks, gophers).

Most shots under 100 yds, but like the idea of reaching out to 200 yds or so for hogs.

My research has basically lead me to low power variable vs RDS with magnifier.

In the low power variable category, I've honed in on the SWFA SS 1-4/6, same in vortex, and trijicon accupoint.

Some consideration being given to leupold 1.5 and trijicon VCOG. The former makes me hesitate b/c not true 1x...the later because of price (would like to keep it $1200 and under).

Would also consider other brands, but the SS and vortex seem very impressive for the price point. Are they REALLY functional at 1x as a RDS?

What would you recommend?

For my purposes, is a 1-4/6 overkill based on weight and cost? If not, would it be worth the extra money and weight to get 1-6 instead of 1-4? SS vs Vortex vs Accupoint? Something else (nikon 2x7)?

A RDS (leaning towards Eotech 300 blk) with QD magnifier seems like it would be better for my purposes, but would the magnifier do a good enough job at 150-250 yds? Or would I end up wishing I chose a low power variable with mil dot?

Mil dot and MOA are both new to me. Not above taking time to learn, but time constraints and shooting frequency lean me more towards "point and shoot" functionality.

Prefer reticles with red dot functionality. SS, vortex, eotech, and leupold (.300) reticles catch my eye.

Will be 95%+ 100 yds and in for varmints and HD.

Weight is important, but not my primary consideration (won't be humping it anywhere).

Appreciate any advice you could offer this new member to the forum.

Make sure what ever you choose it has target type turrets and a lot of elevation adjustment.  300 blk drops like a rock, so to shoot very far you need alot of adjustment. For 300 yards you need like almost 10 mils of adjustment. 

The SS scopes would be a good choice as they do have a lot.

I've been running 300 variants  for years (blackouts and fireballs and whispers and...) and have now settled into the 2.5-10X mag range for mine, for the following reasons:


1. Shot placement is far, far more important with a bullet that isn't spinning at 250,000RPM and isn't expanding much. 

2.  Follow-up shots are frequent, so the ability to dial up and down quickly on the mag range  pays huge dividends.  I generally take the first shot at 10X with my support hand on the power ring when the shot breaks.  It takes practice, but precision in the first shot is at least as important as field of view in the follow-up.

3.  I like either lots of drop on the reticle (IOR MP8 reticle) or a Christmas tree type reticle (Gen 2 XR), because, as supertool said, 300 subs drop from the sky.  The ability to dope the shot on the turret is a definite advantage, but the ability to precisely hold over is much, much more important. (Must be FFP scope.)

4.  A larger scope on a suppressed 300blackout SBR won't be a problem.  I've run them as short as about 7 inches (which is loud even with a can) up to 16" (where it isn't SBR any more) and bigger scopes aren't problematic.  Balance isn't an issue when you have a relatively large hunk of metal at the end of a short barrel.

5.  Sometimes close shots happen fast, and I seldom feel liker I have too much magnification at 2.5 or 3X.  Always keep the scope at the lowest mag, longer shots usually allow more time to change mag than do short shots.


I have run reflex and red dot sights on my 300 SBRs but always find that I want more precision than they allow.  But, I also take shots out to 200 yards and am comfortable doing so.  At 200 yards, even a very small 2MOA dot is covering 4 inches of target.  If yours is to be a 50-100 yard gun, a red dot might not be problematic (since most SBR subs I have used are 1-1.5MOA guns anyway.)


Lastly, good luck with the factory ammo.  I have never seen a caliber that demanded tuning the way 300 SBRs do.  I've played with many, many hand load recipes and have always found one the gun liked, but have never found a factory load (in subsonic) that ran consistently the way I wanted.


They are very fun!

And, for better or worse, they get much, MUCH attention on ranges.

For those of you with the SS, would you trust it for bump in the night HD?

And would 1-4 be ample for my set up, or is it worth the squeeze to go 1-6?

Rancid Coolaid,
Are you hunting at those distances?
what bullet are you running?

I am hunting up to 200 but am only taking brain shots on pigs or am taking shots on smaller game.


My projectile of choice is a 208 amax, it doesn't expand much at all in soft tissue but messes up bone pretty good at 200.


I do NOT use that rifle for animals that I have to recover.  I hunt one particular spot where the owner gets very upset if animals aren't on the trailer at the end of the hunt, and I don't deploy the SBR with subsonics on those hunts.

Appreciate the insight.

The frequency that I would venture a 200 yd shot would be rare.

Since I will be 100yds and in 99% of the time, I doubt I need that much magnification.

I lean towards a red dot, but don't have the best eyes...hence the desire for a little boost in magnification.

That leaves me with a 1-4/6, a RDS with magnifier, or something like an ACOG 1.5 fixed.

The eotech, SS 1-6, and vortex 1-4 reticles catch my eye, cause the my eye picks the circle up quickly.

Don't care for the SS 1-4 1x reticle view, or the vortex 1-6 1x reticle.

Eotech with magnifier costs the same as SS 1-6, but get more holdover with SS...with similar weight. Wonder if the SS 1-6 would hamper me for HD?

The vortex 1-4 is half the price and lighter than SS 1-6, but less magnification.

Both the SS and Vortex have acceptable eye relief.

A low power fixed Acog is good on weight, but costs almost as much as the SS with a lot less capability...and the 1.5x24 has good eye relief, but no circle dot (my preference)...while the 1.5x16 has the circle dot, but poor eye relief.

Basically, I'm down to eotech with magnifier...vortex 1-4 PST...and SS 1-6.

Just would like to know if the 1x on the vortex and SS are fast enough for close quarters in the middle of the night.

Yes, they are.  There is eye relief, unlike an EoTech or Aimpoint, but with practice, it is quite fast as a "both eyes open" solution.  I am no fan of magnifiers behind red dot scopes, it just doesn't work for me.


The 1-6X SS is a good choice.  I have not run the vortex so cannot say on that, but have used everything else mentioned.  An ACOG isn't a bad idea, but isn't ideal.  I would tend toward a variable - as said above - and the 1-6X seems the best option of those pursued.

I am clueless to this topic.. but I am wondering... what is the appeal of "the SBR with subsonics"?

300 BO was designed to get full powder burn out of a 9" barrel.
So, running an AR in a SBR with a can and subs makes sense

How about a trijicon 1-4x? Based on what u are listing your shooting to be rhat would fit your needs well.

I have on on a .223 ar and really like it

Looked pretty hard at it. Light...good price...good glass...good eye relief

Just don't know if it gives me enough help with holdovers for the 300 blk

the downside to the Accupoints is lack of any real holdover points, I mean you can figure some out..

Seems like you are on the 1-x with 300 BDC holds

Look at the Leupold Mark4

Or the Patrol 1.25 - 4 and learn the corrections needed
