I Tested Beretta M84 Fs BB Air Pistol- An Amazing Blowback Gun To Get Hands-on.

I tested Beretta M84 Fs BB Air Pistol- An amazing Blowback Gun To Get hands-on.

I tested the Beretta 84FS CO2 BB .177Cal, 4.5mm Air Pistol By Airsoft Gun India from 30 feet back shooting at a paper target using a semi-rested position (sand bag up front and standing in the back). My 10-shot grouping was just a bit above the center bulls’ eye and very well centered left and right All 10 BBs stayed within 1.5 inches with most of them grouping closer to a 1-inch group. The Umarex Beretta Mod. 84 FS also got a respectable 363 fps on this, not the super warm day so I would expect it to hit significantly higher than the claimed 360 fps during hot summer weather.

Build Quality: 
Being a pretty much all metal gun, makes the 
Beretta 84FS CO2 BB .177Cal, 4.5mm Air Pistol By Airsoft Gun India feel solid and sturdy. The only plastic parts on the Umarex 84 FS were the grips and some magazine parts like the CO2 tab. The painted finish is a nice satin black. The fit and finish on this Umarex CO2 Blowback BB pistol are top-notch with virtually no slide slop at all.

Beretta 84FS CO2 BB .177Cal, 4.5mm Air Pistol By Airsoft Gun India is a fully licensed replica of the real steel Beretta Model 84 FS. It is an extremely close copy in both looks and feel, and has a nice snappy blowback action and field strips just like a real Beretta 84 FS. You'll also find a full-size drop-out magazine that holds the CO2 and BBs and a working slide catch/release that locks back when the magazine is empty.


Trigger Pull: 
The trigger pulls on the Beretta 84FS CO2 BB .177Cal, 4.5mm Air Pistol By Airsoft Gun India 
is fairly long but in terms of resistance is about a medium pull, there is no double action so single action only but the pull is longer than most single action triggers to accommodate the BB chamber mechanism on the magazine. Basically, a BB is pushed into the breach/barrel during the first half of the trigger pull, then the trigger is released. I did notice a fair bit of friction during the BB loading stage and it has been recommended to lubricate this area of the magazine to smooth out the trigger pull.
