www.ReplicaAirguns.com In this Preview Unboxing Video I take a look at two full auto BB Machine guns but both very different and both from two separate companies. One is traditionally CO2 operated and the other is AEG operated which is a very new concept for a 4.5mm Steel BB Airgun. I have always wondered why nobody had attempted an AEG 4.5mm Steel BB gun before so here we have the first one to be released… Starting with the Crosman R1 Fallen Patriots Full Auto CO2 BB Rifle it is essential a re-skinned R1 with a very unique coloration and of course the Fallen Patriots markings on it. The main receiver is a gun metal grey with black and red accents throughout and a purple-blue magazine. It really is stunning to look at and perhaps my favorite Crosman AR series Full Auto BB Gun to date. You do get pop-up Iron sights rather than a red dot which I feel suits this Airgun best and everything else in terms of specifications will be the same as the R1 so check that rifle out for more info. Now the BARRA 400e is really something new to Steel BB Guns, basically it steals the AEG (Automatic Electric Gun) from what is typically reserved for Airsoft Rifles. I have always wondered why this technology has never been transferred over to 4.5mm Steel BB Airguns? Well now it has with the BARRA 400e Full Auto AEG BB Rifle. According to BARRA you can export to get around 410 fps and that should be super consistent since there is no CO2 cool down effect. You can also shoot in semi or full auto and it has a 50 round magazine that comes with a speed loader for easy loading. Another point to mention is that the BARRA 400e is almost all metal and feels really solid.
