Today we look at the velocity of the Makarov MP 654K BB pistol made from Makarov firearm parts. Is it powerful? Does the slide blow back? Does it even work?

Catalog gun?

I discovered or rediscovered something today that has eluded me thus far. The muzzle is painted red. I probably didn’t notice it initially because I am battling red/green colorblindness. Since not many of these BB pistols made it into the U.S. market I’m guessing this could be a gun that someone in EAA painted to look less threatening. That could either have been for a catalog shot or for display at a trade show where the public is admitted. Anyhow, the color is wrong (blaze orange or blaze green are the approved colors) so it is superfluous.

Mak muzzle
Someone painted the muzzle of this Mak — to make it appear safer? I have enhanced the image to make the color appear brighter. But it’s still not the approved color for airsoft guns and therefore isn’t a legitimate marking.

Piercing the cartridge

I wondered if this pistol would still hold gas. As I turned the lanyard swivel at the base of the magazine, the gas started to hiss. One more turn and it stopped. The pistol holds fine! And after the test I removed the CO2 cartridge to keep from compressing the face seal.

The test

I decided to test the pistol with premium steel BBs, Smart Shot lead BBs and Dust Devils. You will see how I got the shot count as the report unfolds.

I also decided to test the muzzle report. Heck — I rent that app every month. Might as well get my money’s worth! Let’s get started.

Build a Custom Airgun

Hornady Black Diamond

For the premium steel BB I chose Hornady Black Diamonds. I was completely unaware of what was coming. I tried to do a test within a test, but as you will see, it backfired.

The first BB went out at 446 f.p.s. Wow! Very strong! I had manually cocked the hammer for that one, so I thought I’d try double action for the next shot and then for every other shot in the string of 10 — a test within a test.

The next shot, fired double action, went out at 411 f.p.s. Okay, there is a difference. But now let me show you the whole string and why my test within a test didn’t work.

1…………….446 SA
2…………….411 DA
3…………….435 SA
4…………….424 DA
5…………….414 SA
6…………….312 DA — Huh?
7…………….400 SA
8…………….387 DA
9…………….363 SA
10…………..399 DA

It seemed like I was getting a two-part velocity table until shot number 6. I could hear that the shot was far less powerful and beyond question the chronograph shows that it was. I will have to watch that.

The average velocity was 399 f.p.s. The low was 312 and the high was 446 f.p.s. — a difference of 134 f.p.s. What is happening? I think a lot of this is the fact that the valve is breaking in. This pistol has never been shot that I know of in over 20 years, so it’s a little sticky. Beyond that I don’t know.

No blowback

The slide definitely does not blow back. Several readers who are far more knowledgeable about Makarovs than I had mentioned that. Oh, and from the date code in the serial number I learned that this Mak was built in 2000. I’m guessing July, because there is a 7 after the first two zeros.

All single shot

I decided to shoot the rest of the shots single action, because the trigger pull is so heavy in double action that I missed the skyscreens on the chronograph. And speaking of chronographs, I didn’t use the new VIKKA chronograph because it would have been too difficult to use with this pistol. Maybe when I receive 45Bravo’s new mounting pad block with Velcro strap things will be easier.

How loud?

I tested the report with my sound meter phone app. At 102.9 decibels it was surprisingly loud.

Mak report

Smart Shot lead BBs

I tried lead Smart Shot BBs next. They are much heavier than conventional steel BBs so we expect them to go slower, and they did. Once again I will show the entire shot string. Remember, every shot was single action.

6…………….did not register
10…………..did not register

The average for this string was 335 f.p.s. The low was 319 and the high was 357 f.p.s. — a difference of 40 f.p.s. Still large but much better than the first string.

Rifled barrel

Some of these BB pistols have rifled barrels and others do not. This one is definitely rifled.

Dust Devils

The last BB I tested was the Air Venturi Dust Devil Mark 2. They are lighter than steel BBs but also a little smaller, so they won’t be much faster, if any. What the heck, here is the whole string.

10…………..did not register

The average for this string was 394 f.p.s. The low was 322 and the high was 447 — a difference of 125 f.p.s. If the valve is breaking in it’s not there yet.

Trigger pull

In single action the trigger broke at 6 lbs. 1 oz. The double action mode is too heavy to measure but I will guess it’s 14-15 lbs. That is a stiff double action trigger pull.

Shot count

At this point in the test 31 shots had been fired. I fired 21 more and then recorded shot 52 with the Hornady Black Diamond at 380 f.p.s. The pistol is still doing well.

Shot 60 went out at 316 f.p.s. I would say the liquid CO2 has run out and the gun is running on residual gas. Shot 70 was 271 f.p.s. which confirmed that the gas was running out. Shot 80 was 128 f.p.s. and I ended the test there.

The verdict?

So far this pistol is not looking like a shooter. But accuracy is next and if it surprises us there, I would change my opinion.

  1. BB,

    Would adding more lubrication make this Mak more consistent in function? Seems like you should give it another round of functions runs before doing more speed and accuracy tests since it has been probably years since it has been used well.


    PS: Section Piercing the cartridge 1st sentence: “I wondered is (if) this pistol would still hold gas.

  2. B. B.
    Accuracy would be a BIG surprise and the trigger will get a little better but only after hundreds of shots.
    One has to love them for what they are;
    a co2 version of a real eastern block service pistol from a bygone era.

  3. BB,

    Did you ever get your hands on a Kalashnikov bb gun? It would have been nice to review it and compare it to a “new” bb gun.

    I would have to say that I would like one of these for my “collection”.

  4. Today’s article inspired me to measure the trigger pull on my Gletcher made Makarov (about which I learnt from reader Michael – thanks again). It appears to shoot with a pull of about 1,78 kg (3lbs 15oz).

    I have not yet got myself one of those fancy electric fingers, so I improvised:

    Wrapped some string around the trigger and tied the other end to a handle of a large 1/2 litre yoghurt pot (I like genuine greek yoghurt, it’s so creamy!). Then, while holding the pistol, pointing upwards (in my workshop, to contain the bb), I pre-weighted the pot with a bottle of bbs and an old penknife and then, poured in water until… bang! πŸ™‚
    Tested and worked several times, so I placed the pot with it’s contents on the kitchen scales which read 1780 grams.

    I am surprised how much heavier it feels to hold up that weight using a whole hand, when compared to shooting with one finger. πŸ™‚

      • Tom Gaylord (B.B. Pelletier), I have discovered that, mixed 50:50 with liquid cream, it creates a superb blend for an ice cream maker. Just add any (!) flavour (normally I squirt in some concentrated juice, for example peach cordial, however, a banana too ripe to eat will suffice, especially with a bit of caramel sauce).

        Now, how can I make the above relevant, ie there must be some way of connecting ice cream to airguns… hmm! πŸ™‚

        • Hi3,

          Edie’s ice cream — 16 ounces (454 grams) fresh strawberries (or thawed frozen one), one cup (one-quarter liter) of artificial sweetener and 24 ounces (680 grams) of small curd cottage cheese in a blender. Blend until smooth. Refrigerate.


          • Tom Gaylord (B.B. Pelletier), without loadsa fat’n’sugar… too healthy! πŸ™‚

            Seriously, it intrigues me! I shall look out for the ingredients, though I expect small curd cottage cheese might be a challenge, here in France. Thanks for the suggestion! πŸ™‚

        • B.B.
          Since I am Greek its common knowledge here that yoghurt helps with burnt skin. So if you stay long enough under the sun hunting or shooting to get burnt there’s a connection.
          Now in order for me to get serious I never managed to really reach group with these pistols (five of them) either with rifled or smooth barrels. Your skills may need some help from luck with this one. You can also try lead round balls if you have access to some.
          My best wishes for your efforts.

          • Bill,

            Round lead balls are my big hope. I have Smart Shot, and I also have some Zimmerstutzen lead balls that are a little bit larger. I hope they will help.


          • Bill, how interesting. Once I got over the ‘what a waste of delicious yoghurt’ shock, I remembered that this knowledge might well help with our current shorts and flip flops summer. πŸ™‚

    • And FM thought 99 deg F here in S Flowda was bad…over the last week or so have canceled a couple backyard shoots because it felt like a convection oven outside – hot, dry, wind and high pressure conditions which are unusual combinations here in the summer. But bit the pellet last Friday and got some break-barrel time in. Funny thing, Saturday a crew came by to fix/overhaul our yard sprinkler system; shortly after they left the rains began and continued into Sunday. See? Fixing your irrigation system may be more effective than a rain dance. πŸ™‚

      Even the sun-loving iguanas are staying in the shade.
