Drozd BB machine gun - bulk-fill! - Part 1
by B.B. Pelletier
Before we begin, I have an announcement. The Crosman 2200 I was testing for you is not performing consistently enough for an accuracy test, so I'm sending it off to be overhauled. Until I get it back, that final report will have to wait.
Pyramyd's bulk-fill Drozd is a full-auto airgunner's dream.
There's a lot of interest in BB machine guns these days, and the Drozd is the most available and affordable of the few that are on the market. I reviewed it for you on August 22, 2005, but that was the basic gun. Today I'll start a long look at the model Pyramyd Air has converted to bulk-fill.
Three things keep the Drozd shooting - BBs, CO2 and six AA batteries. The BBs fit in a removable stick magazine that holds 30 at a time. The batteries last a long time, so the only other thing to worry about is the CO2. Because the Drozd is both powerful and fast-firing, you'll go through a 12-gram cartridge pretty quick. With Pyramyd Air's bulk-fill conversion, you'll have more shots than you know what to do with. And, they'll be cheaper, because bulk gas runs less than CO2 cartridges.
The adapter accepts any standard paintball tank, and Pyramyd supplies a huge 20-oz. tank with the gun. It attaches to a dummy cartridge by a flexible hose that allows the magazine to be removed for loading. Once the tank is connected, there's no need to take it off until it's empty, however nothing prevents you from removing it at any time and no gas is lost.
Size and weight
The tank adds length to the gun, turning it from a large machine pistol into a submachine gun. It functions as a shoulder stock, too. The entire setup with batteries, a full tank and BBs weighs about 6 lbs. and is 25.6" overall. Compare that to the standard gun that weighs 3.5 lbs. and measures 13.75" overall. The weight of the tank in back shifts the balance from the front to the rear, but if you keep the tank tucked under your arm, Rambo-style, the balance feels right.
This gun is controlled entirely by electronics. When you pull the trigger, a solenoid, instead of a mechanical piston, fires the gun. A circuit board controls the number of times the gun fires with one pull of the trigger and the number of rounds per minute it fires. Because the powerplant is CO2, the gun cannot shoot continuously or the action would freeze up. It's been set up to fire either one shot per trigger-pull or bursts of three or six shots.
The gun has three controls. A power switch that doubles as a safety, a selector switch that determines the number of shots with one pull of the trigger and another switch that controls the rate of fire or cyclic rate. The gun can be fired as a semiautomatic, or in the burst mode of three or six shots. The rates of fire are 300, 450 and 600 rounds per minute.
The power switch is on the right. In the down position, as it is now, a red light indicates the circuit is live. That means the gun is ready to fire. The selector switch on the left selects 1 shot (semiautomatic), three- or six-shot bursts.
The cyclic switch determines the rate of fire (rounds per minute).
I'll be testing this rifle for accuracy with steel BBs and lead balls. I'll show the results so you can decide which is better. I'm beginning to understand that the Drozd is more like an airsoft gun than an airgun, so perhaps I have been thinking about it the wrong way. It seems that the most avid shooters want the sound of full-auto fire over the last bit of accuracy and power.
