If you live in a banned state like New Jersey or Connecticut, you&#8217;ve seen the trend: the <strong>&#8220;Other Firearm,&#8221;<\/strong> a legal way to have features that are otherwise banned in those states. When I made this video, other firearms were among the best-selling guns in NJ and CT, the store shelves were empty, and you were asking me every single day whether you could build one yourself. So I did. This is my Slav-approved <strong>6.5 Grendel Other Firearm<\/strong>, built around a 12.5&#8243; Rainier Arms match barrel.<\/p>\n<p><em>Disclosure: Parts were provided by Rainier Arms, Mission First Tactical, Ruger, FAB Defense, and Wojtek Weaponry for testing and evaluation. The companies did not see the video before it was published.<\/em><\/p>\n<p><em>Heads-up: I filmed this in October 2020. Gun laws and regulations (including how pistol braces are treated) have changed since then, so treat the legal discussion below as what I understood at the time, not legal advice. Verify current federal and state law before you buy or build anything.<\/em><\/p>\n<p><iframe loading=\"lazy\" title=\"BEFORE You Buy An &quot;Other Firearm,&quot; WATCH THIS!\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/frCwOzuJ0Gk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<hr \/>\n<h2>What is an &#8220;Other Firearm&#8221;?<\/h2>\n<p>One of the most popular series on the channel has been on this category: the <strong>Troy A4<\/strong> in both 9mm and .223 in a number of barrel lengths, plus the feature-packed <strong>Dark Storm Industries Variant 1<\/strong>. Here&#8217;s the definition one more time (for like the fifth time):<\/p>\n<ul>\n<li>It&#8217;s <strong>not a rifle<\/strong>, because it isn&#8217;t designed to be fired from the shoulder with a stock.<\/li>\n<li>It&#8217;s <strong>not a pistol<\/strong>, because it&#8217;s designed to be fired with two hands, including a <strong>vertical foregrip<\/strong>.<\/li>\n<li>It&#8217;s <strong>not an AOW<\/strong> (Any Other Weapon), because the overall length from the back of the buffer tube to the tip of the barrel is <strong>over 26 inches<\/strong>.<\/li>\n<\/ul>\n<p>That&#8217;s why other firearms typically have a vertical foregrip and are built around a 12&#8243; or 12.5&#8243; barrel. And don&#8217;t confuse an AOW with an Other Firearm. That one inch is the difference between something that has to be registered with the ATF and state police, and a gun that was simply transferred based on its lower receiver.<\/p>\n<h2>Can you build one yourself?<\/h2>\n<p>At the time, yes, as long as it&#8217;s put together from a <strong>virgin lower receiver<\/strong> that was never sold as a rifle. That means you can&#8217;t take your Ruger AR-556 or Smith &amp; Wesson M&amp;P15 and convert it. It has to start as a brand-new lower that was sold as a lower.<\/p>\n<p><strong>What about New York?<\/strong> I got that question almost every other day. You can probably find an FFL selling them, but nearly everyone I talked to at the manufacturer level believed it&#8217;s <strong>not legal in New York<\/strong>. Other firearms worked in NJ and CT because the evil-features laws were written for long guns and pistols, and other firearms are, well, other firearms. New York&#8217;s SAFE Act is written so it applies to receivers too, which makes the whole configuration moot since it uses an AR-15 lower. In New York you&#8217;re looking at featureless builds or the newer fixed-magazine options, like the ones from Dark Storm Industries, a New York-based manufacturer.<\/p>\n<p><strong>And if you live in free America?<\/strong> For you, an other firearm is essentially a way to legally have a vertical foregrip on an AR pistol, just a little longer overall.<\/p>\n<h2>The goal: 1,000 yards from an Other Firearm<\/h2>\n<p>I&#8217;d already reviewed a bunch of Troy and DSI options in .223 and 9mm, and most other firearms out there are in those calibers. I wanted something quite a bit different: <strong>could an other firearm hit steel at 1,000 yards?<\/strong> I reached out to a number of companies with my slightly nutty goal, combined their parts with a virgin lower I&#8217;d been saving and a few small parts I had, and this is Slav-approved build number two.<\/p>\n<h2>The upper<\/h2>\n<ul>\n<li><strong>Barrel: Rainier Arms 12.5&#8243; 6.5 Grendel Match.<\/strong> If you&#8217;re not familiar, 6.5 Grendel is in a sense a necked-down 7.62&#215;39. It still fits the AR-15 platform but delivers more energy and extends usable range by a few hundred yards over .223. I&#8217;ve used Rainier barrels before and liked the value. The Match series gives you much of the quality of their Ultra Match at a more attractive price; this one was around $225 to $250 when I filmed. Rainier guarantees these barrels will shoot sub-MOA with match-grade ammo, and I fully plan to test that. It has a 1:8 twist, standard for 6.5 Grendel, and is threaded 5\/8&#215;24.<\/li>\n<li><strong>Why 12.5&#8243; and not 12&#8243;?<\/strong> You generally need 12 to 12.5 inches to clear the 26&#8243; overall length. You can get shorter by permanently attaching a muzzle device, but I no longer live in New Jersey, so I stayed with 12.5&#8243; for the flexibility to swap muzzle devices. The extra length also helps velocity, which I&#8217;ll need at 1,000 yards.<\/li>\n<li><strong>Muzzle: Patriot Valley Arms Jet Blast compensator.<\/strong> Insanely effective, and self-timing: no shims, just thread it on, align it, and hand-tighten the lock ring. It&#8217;s also threaded for a Rugged suppressor, so you get a good brake and can throw on a good can whenever you feel like it.<\/li>\n<li><strong>Gas: Wojtek Weaponry adjustable gas block.<\/strong> Since I planned to run it with and without a suppressor and wanted to tune recoil, I went adjustable. Mine is the clamp-on version; they also make a traditional set-screw mount. Very reasonably priced and it has been quite effective.<\/li>\n<li><strong>Upper receiver and rail:<\/strong> I repurposed an older, unused upper (I believe from Spike&#8217;s) and a <strong>Troy Alpha rail<\/strong>, one of my favorite rails for a long time.<\/li>\n<li><strong>BCG:<\/strong> An existing nickel boron bolt carrier group from AIM Surplus, with the bolt swapped for a 6.5 Grendel bolt.<\/li>\n<li><strong>Charging handle: Cedar Mill Firearms ambidextrous extended.<\/strong> At around $40 it&#8217;s a very nice upgrade, and if you&#8217;re running a scope you absolutely need something like it to manipulate the gun.<\/li>\n<li><strong>Vertical foregrip: Grip-Pod.<\/strong> This is the part that keeps it an other firearm. I&#8217;d had it for a while without a use; for this build and the 1,000-yard goal, it&#8217;s perfect.<\/li>\n<li><strong>Deflector Brake from Havoc Tactical Solutions.<\/strong> I put these on all my ARs. 6.5 Grendel brass is expensive, and the Deflector Brake reduces dings on the necks and how much the brass gets worked during resizing.<\/li>\n<li>Completing the upper is a run-of-the-mill carbine gas tube.<\/li>\n<\/ul>\n<h2>The lower<\/h2>\n<ul>\n<li><strong>Virgin Spike&#8217;s AR-15 lower<\/strong>, engraved with the NJGunForums logo, which felt very appropriate for this build.<\/li>\n<li><strong>Palmetto State Armory lower parts kit.<\/strong><\/li>\n<li><strong>Ruger Elite 452 trigger.<\/strong> An excellent 4.5 lb two-stage trigger with very short take-up and a clean break, far better than standard mil-spec, and attractively priced at around $150 or less when I filmed. It comes in a housing you can also use with your existing trigger as a dry-fire aid.<\/li>\n<li><strong>FAB Gradus grip.<\/strong> My new favorite AR pistol grip. It&#8217;s upright and works for both run-and-gun and precision shooting. It&#8217;s part of FAB&#8217;s precision package of upgrades along with their adjustable stock and the Spike bipod.<\/li>\n<li><strong>Mission First Tactical oversized trigger guard.<\/strong> Easy to install and makes the gun easier to use with gloves.<\/li>\n<li><strong>Mission First Tactical pistol brace.<\/strong> The other required part of an other firearm. I usually run SB Tactical braces like the SBA3, but I wanted to try the MFT brace because it&#8217;s an awesome value from a great company. Note that it doesn&#8217;t adjust; you lock it at your desired arm length.<\/li>\n<\/ul>\n<h2>Optics and magazines<\/h2>\n<p>For now it wears the <strong>Leupold Freedom RDS<\/strong>, co-witnessed with <strong>FAB backup sights<\/strong>. It was my first time using those sights, and they seem very sturdy and are easy to adjust. For longer distances I&#8217;ll swap in either a low-power variable like the Styrka S7 or a higher-magnification optic for accuracy testing, such as the Vortex Strike Eagle or the 5-25 my friend Alex at Affordable Optics let me borrow.<\/p>\n<p>For magazines I&#8217;m running a combination of the <strong>Amend2 polymer 10-rounders<\/strong> and the <strong>Duramag 20-rounders<\/strong>. If you need 6.5 Grendel \/ 6mm ARC mags, here are the <a href=\"https:\/\/slav.li\/Duramag20GMW\" target=\"_blank\" rel=\"noopener\">Duramag 20-round stainless magazines at GunMag Warehouse<\/a>.<\/p>\n<h2>At the range<\/h2>\n<p>The reason that Jet Blast is on there: once you bring another firearm back to free America, you can put a Rugged Surge on it (suppressors are NFA items, so that means a tax stamp and a dealer transfer where they&#8217;re legal). Holy blowback with the can on, but much quieter. The red dot also kept flickering on and off on me; turns out the battery was dead.<\/p>\n<h2>Can you squat it?<\/h2>\n<p>Without the brake it might be a little more difficult, because you definitely feel the recoil, especially with that thin piece of plastic brace against you. With the brake? It rocks back a little, but it&#8217;s <strong>totally squattable<\/strong>.<\/p>\n<h2>Bottom line: the risks<\/h2>\n<p>Putting together an other firearm is a relatively simple proposition for those in New Jersey and Connecticut. But there are risks:<\/p>\n<ul>\n<li><strong>Redefinition.<\/strong> There&#8217;s always a chance NJ and CT go after other firearms, and there likely wouldn&#8217;t be any grandfathering. The good news at the time: changes seemed like they&#8217;d need to happen legislatively, and there were already over ten thousand factory other firearms in those states, not counting home builds.<\/li>\n<li><strong>No state police letter.<\/strong> As far as I knew, only the Troy A4 and the Dark Storm Industries other firearms had a letter stating they were examined by the New Jersey State Police and found compliant. For many people that&#8217;s worth paying more for to sleep well at night.<\/li>\n<li><strong>You&#8217;re responsible.<\/strong> If you get hassled at the range or pulled over, how comfortable are you explaining why this is an other firearm and not a pistol with an illegal vertical grip, or an SBR? When you build your own, it&#8217;s on you to stay within the confines of an other firearm and not accidentally build a pistol, a rifle, or an AOW.<\/li>\n<\/ul>\n<p>I&#8217;m quite happy with how this turned out, and it was the only way I could get a 6.5 Grendel with the components I wanted. Next up, I&#8217;ll swap the red dot for a scope and shoot some groups. I&#8217;m very interested to see how far out that 12.5&#8243; Rainier barrel can hold sub-MOA.<\/p>\n<p>Gear I use: <a href=\"https:\/\/slav.li\/amazon\" target=\"_blank\" rel=\"noopener\">slav.li\/amazon<\/a>.
