P4Xi 1-4x24 is rated 4.8 out of 5 by 33.
Rated 5 out of 5 by from Steiner P4Xi 1-4x24mm This optic has been good to me so far. I've taken it out to the range 3 times and it's held up to my usage. The glass quality is superb. It is not a true 1x scope, but it's pretty close. The illuminated red dot really sets it apart from others. A throw lever is a must-have because the dial is pretty stuff to adjust. Also, a lot of people mention that the turrets are a little bit mushy, while this is true, the scope is a set it and forget it type. Zero the optic and place the covers on the turrets, then you'll never feel the mushy turrets ever again. I would give this optic a 4/5 stars, only because i've had it for a short time. I really do enjoy this optic, and I'm glad I went with Steiner.

Rated 5 out of 5 by from Just received yesterday What a great scope. I received the scope yesterday. I have waited over a year to purchase a scope for my AR-15. A guy I follow on Instagram had just ordered this. I had never heard of it. After my research, I concluded this is the scope to have. The optic quality is above top notch. The red dot range is perfect. The included throw lever is a very nice bonus. The perfect size and optic range. Great German optics. I hope to shoot it this weekend. Keep up the great job Steiner on quality, American Made products.

Rated 5 out of 5 by from Excellent Glass Very impressive. Bright, clear glass. Very clean and distinct etched reticle. The red dot is vey crisp and perfectly centered. It is daylight bright on some of the lower settings even in sun. 1X seems truly 1X with no distortion or anything. Very rugged, zeroing took only a few clicks each way. Compared back to back to. trijicon TR24 the glass is equal if not better. Much prefer the red dot to the green triangle. No negatives at all. Very impressive and for the price I don't think you can get much nicer.

Rated 5 out of 5 by from Wow Factor! I'm very satisfied with all the features. The Steiner P4Xi is optically clean, with extremely bright and crisp resolution. The ample internal adjustment easily corrected some otherwise difficult mounting issues. The etched glass reticle is flawless and well defined. The illuminated dot is the perfect size, with eleven brightness settings allowing the perfect illumination level for any lighting condition. I like the lower settings in daylight, giving just enough illumination without aberration. The low profile capped turrets are nice, the scope adjustments stay put. The compact overall size is a plus as is the lifetime warranty. This scope is made in the USA and item #5202 comes with a free "throw lever", a very useful upgrade. Factoring in the modest price tag this scope is simply amazing.

Rated 5 out of 5 by from 4.5/5 stars Great Value optic Great optic. Can only compare to Vortex Strike Eagle, and Trijicon ACOG..With that being said. PRO: The glass is clear. the red dot is daylight bright even in the Arizona sun. The reticle itself is simple, clean and easy to use. The build quality of the scope is amazing, especially considered its price. CON: Newish scope that lacks detailed documentation ( What size power ring is the optic, so you can purchase a throw lever?) The 1x isnt a true 1x, its slightly larger. Still very workable and quick, better than other 1-x scopes I have used in the past.

Rated 5 out of 5 by from An incredible deal This optic is superb. It is amazing that they are selling this scope for the price that they are. The glass for this optic was confirmed to be of the same quality as their 1-5 which is far more than double the price!! Im almost afraid to put that in the review with the thought that they will realize that and double the price. The clarity of the glass is unrivaled by any glass I've looked through and keeps that clarity all the way out to 4 magnification. The dot is crisp and draws the eye and does not have any ghosting. The crosshair is simple yet extremely useful although I do wish it had windage marks. The included throw lever also seems to be of very high quality and is easy to install. As others have said the only real cons are the "mushiness" of the dials. Its not a big enough deal for me to think about it but I do wish they had made them a little more positive. Overall an amazing deal and I will be buying at least one more while these scopes stay at this price and are readily available. You WONT be disappointed with your purchase.

Rated 4 out of 5 by from Got it, and the new mount..... I ordered a PX4 as a Fathers Day gift for myself and so I could get one with the free Steiner mount and magnification throw lever. I ordered on line from an approved vendor. The scope came in, it had a small scratch in front of the powder adjustment ring and for some reason I had trouble getting the reticle focused. The scratch wasn't so bad that I actually thought about keeping the scope anyway, but the reticle issued bothered me, so I contacted the vendor, they sent out another scope right away and sent me the 100% free return label for the first scope. The second scope actually came in on the same day as I got the return label via email, so I had the ability to compare the two scopes. The second one had no blemishes, but the dot on the second seemed to work better (it made me realize that the dot on the first one, even though it was definitely daylight visible, wasn't nearly as bright on the highest of settings in comparison to #2). One major problem with scope #2 though was that the bottom leg of the vertical reticle line was "bent" (See picture). Yes, it was actually curved to the left, all the way up into the ranging cross-hash marks. The retailer was amazed when I told the rep this problem and they were willing to send me another, but instead, since the LED was much brighter on this one, I decided to just go through Steiner warranty service and get this one fixed so I could apply for my free mount while #2 was in the shop. Steiner sent me another return label no questions asked and off it went, free of charge. BTW, the optical quality of the glass on both of the first 2 scopes was excellent and I own many other fairly expensive pieces of glass to compare it to (Leupold Mk4-M1, Nightforce, a couple Vortex PST's, and a Meopta). The problem was essentially with the P4X reticle alone. Anyway, Steiner had a brand new scope in my possession within a week or two. This one was cosmetically flawless, the reticle was perfect and focused nice and sharp, the glass' optical quality was "Steiner excellent" like the other 2 and even the red dot was nice and bright like scope #2 was. SWEET! About a week ago, I got my free mount too. Nice mount! Well machined and I love the built in bubble level. This level would be especially handy for a 7.62mm version of an AR; for 5.56mm, due to the much shorter effective range of that round, it's probably overkill, but still nice! Last night I finally got a chance to mount the scope on my AR.... Aaaarrrrgggghhhhh....! The mount is not high enough so that the eyepiece bell can clear my rear backup sight (Magpul MBUS)!!! Kinda disappointing after all of the above process... BUT, the eye relief on the scope might be long enough so that I can move the MBUS way back on the receiver rail and put the scope/eyepiece far enough forward to still get a good sight picture.. It was late last night so I didn't get a chance to play with it to see if this will work just yet... Even though the above "problems" sound like I should really be knocking this scope down, since I knew I'd be waiting for the free mount to arrive anyway, and since all the returns, etc... didn't cost me more than a few minutes of my time, I WOULD still recommend the Steiner P4X scope. Optical quality is excellent. I love the simplicity of the reticle compared to say a Vortex Strike Eagle. The LED dot inside the P4X is AWESOMELY SMALL (and bright!) so that even at 300+ yards, the dot will not obscure a lot of even a small sized target With the true 1X level of non-magnification, the P4X offers an even better field of view than the many Aimpoints I own (PRO's, Comp M2 & M4's). Even the Trijicon MRO can barely compare in this field of view comparison, AND, the P4X will dial up to an adequate 4X magnification when the targeting parameters and distance calls for it. Just MAKE THE MOUNT 1/4" TO 3/8" HIGHER GUYS SO MY MBUS WILL FIT UNDERNEATH THE EYEPIECE!!! ;-)

Rated 5 out of 5 by from Steiner P4Xi I recently purchased this to mount on a BCM rifle. It has been through a Frank Proctor class and has several thousand rounds through it. The scope has been banged around and has not been "babied." I have shot it from 1 to 460 yards. The dot is perfect for both CQB and long-distance shooting. My only complaint is the "mushey" feel between intensity level settings. I would definitely buy this scope again. It is much better than my department-issued Leupold VXR-Patrol.

Will the illuminated dot be blurred by astigmatism? I've noticed in some etched glass it doesn't (prism scopes), but I looked at another scope where just a dot was illuminated and it was distorted.

Asked by: gogobuffalo
Typically, astigmatism will distort projected aiming point, but with the P4Xi having an etched reticle, it should have no more distortion than the reticle of any other riflescope.
