Fox Airsoft give their take on the Elite Force Avalon MP5 Elite AEG which is of course has VFC as OEM for this... "The Elite lineup of MP5's from Elite Force are licensed airsoft replicas of the famous H&K MP5 series. These are metal pro-line AEG versions of the MP5 and feature a very solid metal construction matched with a highly tuned gearbox. These MP5s are produced in partnership under license between Elite Force (Umarex) and VFC (VegaForceCompany) and feature realistic markings and superb performance.

The Avalon lineup within Elite Force's offerings represent VFC's high grade internals. These will feature an electronic MOSFET for the most electrical efficiency, high quality air seal and compression components for the most consistent performance, a quick change spring guide, and a brass 6.03mm tight bore to improve accuracy."
