Awesome Value

by Matt S., Gear Expert from IL, United States Written on November 22, 2017
Great magnifier that fits nicely into a vacant market space.

I've used the Vortex 3x and the EoTech 3x magnifiers. For those on a budget the Vortex is perfectly adequate and the EoTech is pretty much the best if you throw budget out the window.

The Juliet4 fits nicely in the middle in terms of price but offers a little more magnification and is very well made.

Comes with shims to align height with optics and you can adjust the magnifier to center the dot.

Flip to side mount is solid with QD lever, won't be easily knocked between positions but doesn't fight the user when trying to flip it in or out of position.

Another quality option packed with value from SIG.
Most Helpful Positive Review Excellent magnifier for those with astigmatism
Not only is this an excellent magnifier both in form and function (easy flip, dot center correction, etc), it turns a blurry dot to a crisp image for those with an astigmatism. The difference is truly remarkable and aligns perfectly with the Romeo red dot platforms - hence Romeo and Juliet :-) Using on a Sig MCX, both red dot and magnifier installed straight out of the box - could not ask for anything more.

sig juliet4 magnifier

by Bwryder71, Verified Owner from IN, United States Written on October 31, 2024
Paired it up with a sig romeo 4s on a 8"300blk and a sig romeo 4h on a 10.5" 5.56. The magnifier is very solid and doesn't loose zero when shooting or moving from one to the other. Lined up without modifications to both. Reticles are very clear with the magnifier. Hold over dots are clear and very easy to see . Moving magnifier to the side and back has a good tight feel. Doesn't rattle and stays in place. Eye box is pretty good. Better than I was expecting. Eye is not right against the magnifier. The 4x magnification is what I needed. Was able to adjust the reticle to have it clear and crisp. Definitely recommended.

Magnifying Greatness

by The Gun Slinger, Verified Owner from CA, United States Written on April 6, 2024
The Juliet4 Magnifier works great for many applications. I matched this with the Sig Romeo 4S in which I’ll be writing a review on as-well. Good for those who want magnification but not to the point of a LPVO. So I really appreciate that they offer it in a 4X Magnifier in which I can still reach to 500 yards easy with the added capability of a clear & presentable target. But what I like about it the most is its compact size yet still having a decent magnification range. So in my case I have a SOPMOD BLOCK 1 in which I only have a limited amount of Picatinny on the top receiver & this magnifier along with the Sig Romeo 4S & a Meprolight flip up rear sight all fit perfectly together. The eye relief is decent you don’t have to get in very close but you do have to get close to the that sight picture. The clicks for adjusting windage & elevation are good they have somewhat of a tactile feel. Well more of a smoother click to be honest but they are strong & stay in place. Very sturdy & satisfying click as you push & pull the magnifier in & out as needed. Comes in a very nice package with two risers, one lens cover, an allen wrench & extra small screws & a manual of course. Overall the Magnifier is rugged as I’ve had it for about 9 months of hard use & have had no problems with it. Great quality I’ll be buying another set of these soon along with the Sig Romeo 4S Red Dot. Go ahead & add it to cart!! I’ll see you at the range baby!!
Pros:
  • Rugged compact magnifier with some reach to it.
Cons:
  • Smooth clicks for windage & elevation adjustments but not bad i just put it as a con because maybe you might prefer tactile audible clicks
Best Used for:
  • Mid - Long range
Would recommend: Yes

Clear as day

by Lets go Brandon, from TX, United States Written on January 3, 2024
Bought this optic on sale to pair with my sig Romeo 4S and it’s a great match. Mounted on my Springfield Saint AR-15 and couldn’t be happier with both of these options. Sig sauer makes decent optics for the price and perfect for home defense for civilian use.
Pros:
  • Very easy installation
  • Very easy to install
  • Very easy installation
Cons:
  • none yet
Best Used for:
  • Springfield Saint AR-15

Sig Juliet4 Magnifier purchase

by Tom, Verified Owner from PA, United States Written on October 24, 2023
Very nice quality magnifier. Aligns perfectly with the Sig Romeo 4 red dot. I have mine mounted on a Daniel Defense DDM4 V7 Pro. It looks great and will be very useful for longer range shooting. I highly recommend not only this magnifier but also anything made by Sig Sauer.

Works great

by Quevin Caldwell, Verified Owner from TX, United States Written on September 9, 2023
Have it on on my AR with a Romeo5XDR. Works great! It has excellent build quality and the glass is very clear. Comes with a removable lense cover as well as replacent lenses . Would definitely recommend to a friend.

Good for the money

by Dave, from HI, United States Written on April 11, 2022
No problem with the price or build quality! If you're low on cash and need pretty nice glass then you should definitely consider SS. Plenty of vids on the net showing the quality. The desert tan version is sweet.

Great magnifier

by Billy, from AL, United States Written on March 14, 2022
This works as advertised. Nicely made and packaged. It is what you would expect from Sig. The mounts are sturdy and easily installed. I paired it with the Romeo and they work very well together. I like the fact that you can quickly flip it to the side if you only wish to use red dot without added magnification.
Pros:
  • Clear optic
  • very sturdy
Cons:
  • None
Best Used for:
  • pair with holographics or red dot sites
Would recommend: Yes

Great with Holosun 510C

by Ken, Verified Owner from VT, United States Written on February 26, 2022
Bought instead of Holosun magnifier due to 4x vs 3x mag, better finish, same price ($311 for this with discount). First Sig product for me, very well packages, came with 2x risers, Allen key, and extra lens cover (replacement). OP shipped for free in 5 days and have me a price better than advertised. QD mount is really solid, won't budge, flips easy, clear glass. Eye relief leaves a bit to be desired, I have to push my face up a bit further on the stock but still good. Need to get range time with it, but first impressions are great.
Pros:
  • Price
  • Build quality
  • glass
  • Adjustment
Cons:
  • Heavy
Would recommend: Yes

Definate plus to a Romeo

by austinshoots, Verified Owner from TX, United States Written on February 23, 2022
Nice quality. Not too long when combined with my Romeo. Definitely needed if you want to see your shot placement. Only conflict I have is whether I prefer my acog with magnification or my Romeo and Juliet combo? Of course the acog costs several hundred more than most Romeo Juliet combos.
Pros:
  • Flip feature, size, warranty
Cons:
  • use of rail space
Best Used for:
  • Target and hunting
Would recommend: Yes

id buy another

by David H, Verified Owner from OH, United States Written on January 8, 2022
Highly recommend this magnifier. Pairs perfectly with the Romeo 7. It will flip both ways if you use the low spacer and the red tipped hardware which aligns the optics correctly. I’m left handed, which makes situations like that a pain. Very clear and I really like the dust cover which has a lens that allows you to view through it. The detent is very solid.
Pros:
  • None
Cons:
  • Price $$$
Would recommend: Yes
