I believe this should greatly aid in preventing the back of the piston from blowing out such as is currently afflicting SHS. In comparison, the SHS piston body feels a little brittle next to this thing. The nylon material itself seems to have a natural &#8220;glide&#8221; to it and it rides easily on any gearbox I&#8217;ve inserted it into.<\/p>\n<p>The method of mounting the rack is still fairly conventional, though there is a full length rail on both sides of the rack for holding it in rather than a partial support like some pistons offer.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1055\" src=\"https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131329-1024x576.jpg\" alt=\"\" width=\"840\" height=\"473\" srcset=\"https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131329-1024x576.jpg 1024w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131329-300x169.jpg 300w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131329-768x432.jpg 768w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131329-1200x675.jpg 1200w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/p>\n<p><strong>3)<\/strong> The rack to piston fit is fairly loose, so glue \/ epoxy is an absolute must (as it is on every piston with a removable rack, for that matter).<\/p>\n<p><strong>4)<\/strong> Weight of the piston is 10g. Not the lightest, but certainly not the heaviest. I&#8217;d definitely swiss-cheese this for any DSG applications. For your typical SSG build, this is not an obstacle to be overcome.<\/p>\n<p><strong>5)<\/strong> The rack comes with the 2nd to last tooth removed, which is always a nice time saver. The teeth are slightly taller than an SHS or CYMA rack from what I can see. The material seems quite strong, and has some very mild flex, but does not feel like it&#8217;s brittle. Actually, I would suspect you could chuck this rack up in a vise and get it to bend 90* and it wouldn&#8217;t snap. The Titanium Nitride coating on the rack is interesting. Besides offering corrosion resistance, technically this should also provide improved wear resistance for the teeth.<\/p>\n<p><strong>6)<\/strong> Price. This is an expensive piston @ $35, putting it nearly on par with the System Super Core and others. In some respects, I see this as an attempt at a luxury brand pricing strategy, which has a certain merit and strategic significance. We are most certainly in the dawn of the luxury Airsoft gun, with many contenders and brands now breaching the $1000+ price tag. But the key thing here is that it <strong><em>absolutely<\/em><\/strong> has to perform for that price.<\/p>\n<p>Angel Custom has long been the brunt of jokes within the tech community &#8211; and often for a good reason. They don&#8217;t have the greatest track record, and many of the products are of questionable quality. To their credit, Evike recognizes that it&#8217;s an issue and is making an effort to bring in better products and phase out the bad ones. I do question the decision to even brand under the label, but with some blood, sweat and tears (and the all important quality control), even the worst brands can be revitalized.<\/p>\n<p>Stay tuned to future updates once I&#8217;ve had some opportunity to log some serious rounds on these pistons.<\/p>\n<p><strong>Edit 1\/29\/19: <\/strong>I&#8217;ve currently logged just north of 7,500 rounds on this piston without failure. I expect to log quite a bit more this upcoming year as this gun is pushed through its paces at the local fields. At the 10K mark, I will open up the gearbox and visually inspect the piston for wear.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1053\" src=\"https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131216-1024x576.jpg\" alt=\"\" width=\"840\" height=\"473\" srcset=\"https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131216-1024x576.jpg 1024w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131216-300x169.jpg 300w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131216-768x432.jpg 768w, https:\/\/tacticalparts.com\/blog\/wp-content\/uploads\/2018\/12\/20181217_131216-1200x675.jpg 1200w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I am always willing to try out new products, even if they have a storied and ill-gained reputation.
