{"product_id":"airsoftpro-m249-hop-up-yksikko-gen-2","title":"AirsoftPro M249 hop-up unit, gen. 2","description":"\u003cp\u003eThe second-generation AirsoftPro hop-up unit for M249 airsoft machine guns is CNC-machined from a single piece of 6061-T6 aluminum. The surface of the unit is finished with a fine red anodization. The 6061-T6 material combines durability and light weight, with the entire unit weighing only 29 grams. A high-quality hop-up unit is one of the most essential components when aiming for an accurate and high-performance airsoft gun.\u003c\/p\u003e\n\u003ch5\u003eQUALITY AND SMART SOLUTIONS\u003c\/h5\u003e\n\u003cp\u003eOne advantage of the second-generation M249 over the previous model is the numbered and notched adjustment ring, as well as a completely redesigned pressure arm. The adjustment ring clearly shows the hop-up setting level on a ten-step scale, and the notched adjustment ensures the hop-up stays in the desired position.\u003c\/p\u003e\n\u003cp\u003eThe original M249 pressure arm differs significantly from traditional arms and is generally considered inferior compared to the U-shaped arms found in standard AEGs. In the AirsoftPro Gen. 2 M249 hop-up, the pressure arm is U-shaped, and its adjustment is designed so that the arm moves vertically in its track (TDC).\u003c\/p\u003e\n\u003cdiv class=\"span4\"\u003e\u003cimg class=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/6636\/2610\/files\/m249-03.jpg\" alt=\"AirsoftPro Hop-up chamber for M249\" width=\"593\" height=\"339\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision CNC-machined construction.\u003c\/li\u003e\n\u003cli\u003eDurable one-piece red anodized body.\u003c\/li\u003e\n\u003cli\u003eMetal adjustment ring with notches.\u003c\/li\u003e\n\u003cli\u003eTraditional U-shaped pressure arm.\u003c\/li\u003e\n\u003cli\u003eLaser-marked numbers for easy hop-up adjustment.\u003c\/li\u003e\n\u003cli\u003eCompatible with the following \u003cstrong\u003eM249\u003c\/strong\u003e machine guns: \u003cstrong\u003eA\u0026amp;K, PJ, Classic Army, Echo1, Matrix\u003c\/strong\u003e (tested with original nozzles).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUnit + adjustment ring\u003c\/li\u003e\n\u003cli\u003eBrass barrel centering ring\u003c\/li\u003e\n\u003cli\u003eU-shaped pressure arm\u003c\/li\u003e\n\u003cli\u003eSpring + ball bearing for locking the adjustment ring\u003c\/li\u003e\n\u003cli\u003eO-ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cdiv class=\"avPlayerWrapper avVideo\"\u003e\n\u003cdiv class=\"avPlayerContainer\"\u003e\n\u003cdiv id=\"AVPlayerID_0_a1e3b1a42e86ec8e74ed3082595f89f7\" class=\"avPlayerBlock\"\u003e\u003ciframe title=\"JoomlaWorks AllVideos Player\" src=\"https:\/\/www.youtube.com\/embed\/WKCZeBooVhc?rel=0\u0026amp;fs=1\u0026amp;wmode=transparent\" width=\"400\" height=\"300\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptimal performance requires excellent compatibility between the nozzle and hop-up bucking.
