With the single-billet receiver and fore-end carved &apos;from the solid&apos;, you get no muzzle-flip, and essentially no recoil. It&apos;s a pure blow-back design, and it needs a very little in the way of maintenance - cleaning is simplicity itself.The receiver fits perfectly in any standard AR-15 lower receiver, and there are picatinny rails in all the usual places. There&apos;s *just* enough room to set both optics and off-set iron sights, if you *really* must have both. Realistically, the rear-most top rail can only accommodate relatively short optics, or you start to interfere with the magazine. The rails themselves are perhaps a bit narrower than standard; Magpul accessories fit perfectly, but other accessories may need a bit of shimming to ensure a tight fit.Magazine changes are a bit odd, but you&apos;ll get used to them. Be *certain* to buy quality magazines - I bought two off-brand magazines from another vendor, and had both fail at exactly the same point, in exactly the same way - poor-quality follower springs took a &apos;set&apos; and failed to cleanly feed a round, resulting in a failure-to-feed jams. Speaking of which - familiarize yourself with the operation of the magazines and clearing failures-to-feed *before* you get to the range - these are NOT like any other firearm you&apos;ve ever fired!Now to the good stuff: Firing it!The AR-57 has essentially NO perceptible recoil. It&apos;s not a long-range sniping weapon; it&apos;s a short-range light-duty carbine. It&apos;s more than adequately accurate within its useful range - about 150 yards, maximum. It&apos;s also FUN! Load up a 50-round magazine, and it feels like you can shoot all day. Sure, loading the magazine is a bit long-winded, but it&apos;s worth it, especially if you charge several magazines before leaving the house - you can shoot and shoot and shoot! If 5.7x28 ammo were any less expensive, or any easier to reload, I&apos;d be shooting this every day - It&apos;s THAT much fun! I ditched both magnifying optics and iron sights early on - a simple 30mm point sight is really all you need for this upper - you&apos;re not going to be shooting any further than 150 yards, or you&apos;ll be &apos;mortaring&apos; your shots onto the target.If you&apos;ve got varmints - woodchucks, coyotes, gophers - in close quarters, this is perfect. I wouldn&apos;t try taking anything heavier than varmints with this round, though - just not enough &apos;oomph&apos; there. And certainly not at any lengthy range! Tin cans, gourds, and squash, though - Those are in serious danger!The AR-57 has become my new favorite &apos;plinker.&apos; </span> <div class="bvseo-pubdate">Date published: 2014-10-18</div> <meta itemprop="datePublished" content="2014-10-18" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="http://schema.org/Review" data-reviewid="39753098"> <meta itemprop="itemReviewed" content="AR-15 5.7mm Upper Assembly with 16 Barrel" /> <span itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span></span> by <span itemprop="author">DONALD B</span> from <span itemprop="name"></span> <span itemprop="description">Item is better than expected.
