Muzzle velocity test
According to the manufacturer's (APS) data, the muzzle velocity should range between 380 - 410 fps.
According to Taiwangu.com - 400 fps.
Our measurements showed a much higher muzzle velocity.
- 437,9
- 435,5
- 437,4
- 434,7
- 435,4
- 437,8
- 435,4
- 439,9
- 435,7
- 439,5
Average: 436,9 fps
The kinetic energy of the 0.2 g BB at the barrel exit: 1.77 J
It is worth emphasizing very similar readings - the spread was about 5 fps. This is a very good result in the replica straight from the box.
The tests were carried out on our own enclosed shooting range, at an ambient temperature of 22oC, the Hop-Up was set to zero. The measurements were made with the XCORTECH X3500 chronograph using Open Blaster 0.2 g BBs.
ROF using a LiPo 11,1 V 1200 mAh - 16,3 BBs/s.
Target shooting test
We used 0.25 g G&G BBs for this test. The distance to the target - 25 m. Shooting was done form the K-Zone gun shooting rest.
10 shots were fired from a replica pulled straight out of the box.
All shots hit the target.
Single fire shooting results
Maximum spread between shots - 20 cm.
Full-auto fire shooting results
Maximum spread between shots - 9 cm.
Summary
From the technical point of view, we are dealing with a really well-configured and crafted replica. Its performance "out of the box" is at least satisfactory. The stability of muzzle velocity is particularly worth emphasizing. In general terms, the BDR-15 impresses with its accuracy of reproducing a real firearm. All the reservations that I described above are basically cosmetic. Well, maybe except the lack of a dummy gas block and tube. Obviously, the easily removable clearance between the receiver halves remains a drawback.
In terms of usability, first of all I do wish the set included some kind is sights. But maybe this is just another example of faithfulness to the original, which, after all, does not have them either?
Secondly, I have some concerns about the failure-free operation of the mechanism placed in such an openwork body.
Finally, I have in my mind the thought formulated in the foreword of this text: "Who would like to dress up as the world champion in sport shooting?"
