The term refers to firearms being loaded with add-on features that are not really needed for the job. Adjustable sights and target-type triggers on the 1911 handgun, and extended controls and light triggers on service grade <a href=\"https:\/\/www.cheaperthandirt.com\/firearms\/tactical\/ar-15-rifles\/\" target=\"_blank\" rel=\"noreferrer noopener\">AR rifles<\/a> are among these features.<\/p>\n<p>Feature creep makes the firearm incrementally more complex until the original intent is obscured. A real impediment is a designer that thinks his firearm must do everything and anything. I am not an operator, and I have not been on the front line in institutional service in some time. But I know what is needed in personal defense, service use, and in a good general-purpose rifle that will serve many roles well. Treading through a high density of egos, I find that a general consensus of what is needed in a service grade rifle would give us a rifle similar to the <a href=\"https:\/\/www.cheaperthandirt.com\/sig-sauer\/firearms\/rifles\/?brand=SIGSauer&amp;utm_source=blog.cheaperthandirt&amp;utm_medium=referral&amp;utm_campaign=range-report-sig-m400-rifle-beyond-service-grade\" target=\"_blank\" rel=\"noreferrer noopener\">SIG M400<\/a>.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"640\" height=\"428\" alt=\"Woman shouldering a SIG M400 with an attached foregrip\" class=\"wp-image-86577 jetpack-lazy-image\" data-recalc-dims=\"1\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?w=648&amp;ssl=1 648w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=300%2C200&amp;ssl=1 300w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=150%2C100&amp;ssl=1 150w\" data-lazy-sizes=\"(max-width: 640px) 100vw, 640px\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=640%2C428&amp;is-pending-load=1#038;ssl=1\"\/><noscript><img decoding=\"async\" loading=\"lazy\" width=\"640\" height=\"428\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=640%2C428&amp;ssl=1\" alt=\"Woman shouldering a SIG M400 with an attached foregrip\" class=\"wp-image-86577\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?w=648&amp;ssl=1 648w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=300%2C200&amp;ssl=1 300w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-1.jpg?resize=150%2C100&amp;ssl=1 150w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" data-recalc-dims=\"1\"\/><\/noscript><figcaption>As a go anywhere, do anything an AR can do rifle, the SIG M400 has great promise. <\/figcaption><\/figure>\n<\/div>\n<p>Several companies, originally founded to manufacture handguns, eventually offered AR-15 rifles. <a href=\"https:\/\/www.cheaperthandirt.com\/colt\/firearms\/rifles\/?brand=Colt&amp;utm_source=blog.cheaperthandirt&amp;utm_medium=referral&amp;utm_campaign=range-report-sig-m400-rifle-beyond-service-grade\" target=\"_blank\" rel=\"noreferrer noopener\">Colt<\/a>, <a href=\"https:\/\/www.cheaperthandirt.com\/fnh-usa-inc\/firearms\/rifles\/?brand=FNHUSA%2CInc&amp;utm_source=blog.cheaperthandirt&amp;utm_medium=referral&amp;utm_campaign=range-report-sig-m400-rifle-beyond-service-grade\" target=\"_blank\" rel=\"noreferrer noopener\">FN<\/a>, <a href=\"https:\/\/www.cheaperthandirt.com\/ruger\/firearms\/rifles\/?brand=Ruger&amp;utm_source=blog.cheaperthandirt&amp;utm_medium=referral&amp;utm_campaign=range-report-sig-m400-rifle-beyond-service-grade\" target=\"_blank\" rel=\"noreferrer noopener\">Ruger<\/a>, and <a href=\"https:\/\/www.cheaperthandirt.com\/springfield\/firearms\/rifles\/?brand=Springfield&amp;utm_source=blog.cheaperthandirt&amp;utm_medium=referral&amp;utm_campaign=range-report-sig-m400-rifle-beyond-service-grade\" target=\"_blank\" rel=\"noreferrer noopener\">Springfield<\/a> are among them.

One of these is a gas block pinned in place rather than screwed in place. The other is a bolt with the gas keys staked in place properly. I still see mistakes, and all are not home-built rifles. Some of the factory units are \u2018economy rifles.\u2019\u00a0<\/p>\n<p>The TREAD is properly set up for reliability. The handguard is long enough for good purchase and mounting lights, with M-Lok slots spaced on the forward section of the handguard. The stock is the usual six-position adjustable stock \u2014 this one by Magpul. The upper and lower receiver fit well together with minimal play.<\/p>\n<p>The rifle features an ambidextrous safety. The magazine release is also ambidextrous. A good touch is a tension device just below the receiver pin that may be used to tighten the fit between upper and lower receivers.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"383\" height=\"576\" alt=\"Man performing a speed load of the M400 .223\/5.56 rifle while running between positions\" class=\"wp-image-86578 jetpack-lazy-image\" data-recalc-dims=\"1\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?w=383&amp;ssl=1 383w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=199%2C300&amp;ssl=1 199w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=150%2C226&amp;ssl=1 150w\" data-lazy-sizes=\"(max-width: 383px) 100vw, 383px\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=383%2C576&amp;is-pending-load=1#038;ssl=1\"\/><noscript><img decoding=\"async\" loading=\"lazy\" width=\"383\" height=\"576\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=383%2C576&amp;ssl=1\" alt=\"Man performing a speed load of the M400 .223\/5.56 rifle while running between positions\" class=\"wp-image-86578\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?w=383&amp;ssl=1 383w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=199%2C300&amp;ssl=1 199w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-2.jpg?resize=150%2C226&amp;ssl=1 150w\" sizes=\"auto, (max-width: 383px) 100vw, 383px\" data-recalc-dims=\"1\"\/><\/noscript><figcaption>The AR is a very ergonomic performer.

The SIG Romeo red is fast on target with good features making it an effective combat sight. The rifle handles well with a good balance. I leaned against the bole of a tree and took aim at a 50-yard target.<\/p>\n<p>Firing quickly from this brace, I executed several double-taps. The shots were close together, and after firing five double taps, the X-ring had suffered. Settling down to a solid benchrest firing position, I fired the rifle at 50 yards.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"640\" height=\"236\" alt=\"SIG M400 Tread .223\/5.56 rifle with a SIG Romeo red dot sight\" class=\"wp-image-86585 jetpack-lazy-image\" data-recalc-dims=\"1\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?w=648&amp;ssl=1 648w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=300%2C111&amp;ssl=1 300w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=150%2C55&amp;ssl=1 150w\" data-lazy-sizes=\"(max-width: 640px) 100vw, 640px\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=640%2C236&amp;is-pending-load=1#038;ssl=1\"\/><noscript><img decoding=\"async\" loading=\"lazy\" width=\"640\" height=\"236\" src=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=640%2C236&amp;ssl=1\" alt=\"SIG M400 Tread .223\/5.56 rifle with a SIG Romeo red dot sight\" class=\"wp-image-86585\" srcset=\"https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?w=648&amp;ssl=1 648w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=300%2C111&amp;ssl=1 300w, https:\/\/i0.wp.com\/blog.cheaperthandirt.com\/wp-content\/uploads\/2023\/03\/SIG-M400-9.jpg?resize=150%2C55&amp;ssl=1 150w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" data-recalc-dims=\"1\"\/><\/noscript><figcaption>The author\u2019s personal M400 has proven reliable and accurate.<\/figcaption><\/figure>\n<\/div>\n<p>Firing 3-shot groups, the Federal 62-grain and Hornady 55-grain V-Max tied for top accuracy \u2014 just under an inch for three shots. At 100 yards, I fired two 3-shot groups with each load. At this range, the best single effort was 1.5 inches, the average 2.0 inches \u2014 good for a red dot equipped AR-15.<\/p>\n<p>At this point my experience is good but not very in depth. I would expect better results with a bit of exploration into ammunition and more acclimation as well. Just the same, I cannot fault accuracy results in any way. The SIG M400 TREAD never failed to feed, chamber, fire, or eject. The rifle is well made of good material and offers SIG quality at a fair price. It should be on anyone\u2019s short list for a front line AR-15 rifle.<\/p>\n<h4><strong>When it comes to the AR platform, which are our favorites? How does the SIG M400 Tread compare?
