Product Features: 

SCR Reticle

Steiner’s Special Competition Reticle (SCR) is a proprietary reticle designed by Steiner for precision shooting use. An extended illumination area lets the shooter engage targets at long distance even in low light. The vertical crosshair features 1/2-mil marks for distance holdover. The horizontal crosshair offers 1/2-mil and 2/10-mil lines for windage



The windage and elevation knobs

are designed for precise adjustment. The dials are calibrated so that 1 click equals 1 cm @ 100 meters or .1 mRAD for the 4-16x.



Ruggedly constructed

scope tubes are milled from solid, high-grade aluminum stock so there are no welds or seams, for greater strength and durability.

P4Xi 4-16x56 is rated 4.8 out of 5 by 18.
Rated 5 out of 5 by from Good value. The P4xi is back! This is a tough rugged little scope. Super crisp glass, sweet SCR retical and MADE IN USA! Think Leupold in it’s hay day . Steiner’s service after sale is worth the price of the scope alone. As a rancher I know, if you don’t have service for your equipment you don’t have anything. I own multiple Steiner products and they have always addressed any issues I had. Buy one or get one of its bigger brothers and you will not be disappointed! PS The Steiner light transmission and edge clarity is Second to none

Rated 5 out of 5 by from Wow the glass in this scope is awesome! I have Been looking for a few months on what scope I wanted for my Savage MSR 308 Long Range. I wanted something made in the USA with great glass quality. I narrowed it down to Leupold, Steiner and Vortex. After going to a store and reviewing all three it was an easy choice to go with Steiner. That German glass was so clear and just felt so well made. The warranty is the best and the price was competitive to the others as well. It looks incredible on my rifle. I am working up some hand loads to go shooting soon. I will report back as how it preformed in a few weeks.

Rated 5 out of 5 by from Stunning clarity with a very intuitive reticle Just got my P4Xi. The clarity is just breathtaking. Past issues with this scope have been addressed and rectified. This also carries the Steiner Heritage Warranty... forever... not just lifetime. My yet to be born grandkids can warranty this. The lighted reticle isn’t super bright in sun light but that is ok. Love the off setting between settings. No more rotating through brightness to get to what I want. No bloom or wash out and everything is symmetrical with no unevenness. Love the SCR and it is easy for me to make calculations with it. The vertical adjust is tighter than the horizontal and the zoom is tight but not overly. This is an amazing bargain for HD German glass that is made in America. One word... ecstatic. Looks PERFECT on my Tikka.

Rated 5 out of 5 by from P4XI checks all the boxes Spent countless hours reading about scopes in the 1k price range. I narrowed it down to the Steiner P4xi and the Burris XTR II , I gave the edge to the Steiner with turret indicator ( showing when you are in your second rotation) I found the Burris knob to be kinda busy but again that’s my personal preference. Glass is sharp edge to edge and with positive clicks on turret knobs this sealed the deal for me . If your in the market for a new scope I would highly suggest giving the Steiner brand a chance.

Rated 5 out of 5 by from pxi4 4-16 Top product with features as promised. Optics could not be better. Takes more effort to turn adjustments but will ensure longer service life.This a great value for the amount paid.

Rated 4 out of 5 by from Great Glass and light transmission. Been using this for a few months in both a .308 and 6.5cm. The glass is clear and brings in a lot of light. The SCR reticle is decent but there are no aftermarket ballistic programs with options for these reticle. The turrets are Massive and a tad mushy. No discernable clicks. Had to machine my Larue S.T.O.M.P. mount to accommodate the elevation turret at 1.5" its wider than a Schmidt and Bender. The illumination is nice. For the money this a great value and can run with the $2k optics.

Does the P4xi 4-6x56 have the HD glass like the T5xi?

Asked by: Jack67
Yes it does.

Odd, after 2 weeks, my question just disappeared. Is the P4XI rated for use with heavy recoil cartridges like 50 BMG, 408/375 CheyTac, and the 378 Weatherby based cartridges?

Asked by: TxGR
Yes, that should not be a problem.

Is there a sunshade you can recommend/that will fit the pxi-4-16x56? What do you think of the Aadland flip-up covers for this scope?

Asked by: Henry75
Hello, As for the sunshade, the P4 can use the same one that the T5 uses. Those look like nice scope caps, worth a shot! We also recommend Butler Creek

What is the major difference between the p-series 4-16x56 and the T-series 3-15x50 (in term of glasses, turret)? Is P-series a Burris made Steiner?

Asked by: ATsoi
Hello! For a comparison of specs, check out the comparison tool located on the right side of the screen, near the specs. That allows you to look at both optics on one page, side by side.
