The A2 front sight, paired with the Springfield fold-down rear sight (I used the small aperture) made shooting for a group at the MR-31 target pretty easy.<\/p>\n<p>The SAINT <span class=\"nowrap\">M-Lok<\/span> performed admirably at all distances, but the rifle is best suited for self-defense or police duty where lethal threats must be clearly identified and are most likely to be within 100 yards. An 8.5 -25 scope is not the best choice for a defensive carbine, so I mounted a low-power variable optic (LPVO). Specifically, a vintage Leupold Vari X II, 2-7 and zeroed it for 50 yards and practiced some defensive shooting drills.<\/p>\n<figure class=\"wp-block-image size-full\"><picture decoding=\"async\" loading=\"lazy\" class=\"wp-image-46231\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-800x533.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-400x267.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-768x512.jpg.webp 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-600x400.jpg.webp 600w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1400\" height=\"933\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok.jpg\" alt=\"author evaluating the reliability of the saint b5 m-lok\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-800x533.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-400x267.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-768x512.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/author-evaluating-the-reliability-of-the-saint-b5-m-lok-600x400.jpg 600w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption class=\"wp-element-caption\">The author equipped his SAINT rifle with a 2-7x scope, spare magazine, sling and INFORCE WMLx Gen 2 weapon light to demonstrate how the rifle could be carried practically.

The ammunition was fed from 20- and 30-round capacity magazines made by Sentry (Hexmag,) Magpul, NHMTG and Brownells. No malfunctions were experienced.\u00a0<\/p>\n<p>When evaluating the overall quality of a rifle, I want to know if the manufacturer held the headspace as close as possible to the minimum chamber dimensions. A headspace gauge will confirm that a rifle is safe to shoot. I didn\u2019t check the headspace; I presume a production rifle is safe to shoot. What I did do was to check the fired cases in an L.E. Wilson Case Gage to get an idea of how much they expanded.<\/p>\n<p>Reloaders use case gauges to help them correctly set up full-length resizing dies. If the die does not \u201cbump the shoulder back\u201d far enough, a resized case won\u2019t fit in a rifle. Using a case gauge also prevents the reloader from oversizing the case by pushing the shoulder back too far.\u00a0<\/p>\n<figure class=\"wp-block-image size-full flush\"><img decoding=\"async\" loading=\"lazy\" width=\"933\" height=\"920\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint.jpg\" alt=\"chamber size checking the springfield armory saint\" class=\"wp-image-46229\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint.jpg 933w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint-800x789.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint-400x394.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint-768x757.jpg 768w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2023\/08\/chamber-size-checking-the-springfield-armory-saint-600x592.jpg 600w\" sizes=\"auto, (max-width: 933px) 100vw, 933px\"\/><figcaption class=\"wp-element-caption\">L.E. Wilson Case Gage with fired Norma case inside demonstrates that the SAINT\u2019s chamber is properly\u00a0sized.<\/figcaption><\/figure>\n<p>Dropping a few fired cases into a Wilson Case Gage tells me a lot about chamber dimensions and headspace. Sometimes, a fired case has expanded so much that it will barely fit in  \u2014  that tells me that even though a particular rifle fired and cycled properly, the chamber is too large. In other instances, the case drops in most, but not all of the way.<\/p>\n<p>After my range day with the SAINT <span class=\"nowrap\">M-Lok<\/span>, I dropped a few fired cases into a Wilson Gage and they dropped all the way in with almost no resistance. This told me Springfield Armory used a quality reamer, and the chamber is sized correctly. A properly sized chamber will, in most cases, increase accuracy. However, if a chamber is too tight, a semi-automatic rifle will not feed and extract reliably. The folks at Springfield got the SAINT\u2019s chamber dimensions just right.\u00a0<\/p>\n<h2 class=\"wp-block-heading\">Final Thoughts on the Springfield SAINT B5<\/h2>\n<p>The SAINT <span class=\"nowrap\">M-Lok<\/span> is an excellent value for anyone needing a budget-friendly <span class=\"nowrap\">AR-15<\/span> defensive carbine that can be easily upgraded later. For the firearms owner who already owns a few rifles, the competitive pricing of the SAINT B5 Systems <span class=\"nowrap\">M-Lok<\/span> makes it an excellent choice for a spare rifle or a vehicle gun. The folks at Springfield Armory clearly thought this through, and they have a winner.<\/p>\n<p><em>Editor\u2019s Note: Please be sure to check out The Armory Life Forum, where you can comment about our daily articles, as well as just talk guns and gear.
