![]() ![]() If it’s your sort of thing, they come with a threaded barrel so you can mount suppressors or other muzzle-mounted accessories. This GBB simulates recoil impressively and offers crisp, snappy yet fluid cycling. This airsoft pistol offers both semi and fully-automatic modes. (More on that in a moment.) It has an adjustable hop-up system and features a two-stage trigger as well, sort of unique for a GBB that’s capable of extremely hate rates of fire. This airsoft pistol is 230mm long, weighs in at 386g, and comes with a 22 round Action Army AAP-01 Gas Magazine, although it’s compatible with some others. The Action Army AAP-01 is modeled after the Ruger MK4, which itself is a remarkably popular handgun. Let’s peel back some layers, take a look at why this airsoft pistol is so popular, and then make some suggestions for airsoft attachments and ammo. More than likely, if you found this post, you’re already the proud owner of one. ![]() As long as there is nothing for the bb to catch on, the spring inside the mag should have enough force to push the bb through.If there’s an airsoft pistol out there that deserves your attention right now, it’s the Action Army AAP-01. You could add a piece of clear acrylic on the inside to guide the BB if you have to. Just try to make the holes as smooth as possible. You wont have to worry about any suction in the hop-up unit, the nozzle seals off that section when a round is "chambered". This is the datasheet for the Photo Interrupter: (OS25B10) I'd like to put the sensor by the magazine feed, however, I am worried that if I drill a hole through this feed, it may affect the feeding/suction mechanism. Is this sensor capable of measuring the rate of fire at these levels? I'm not so concerned about the muzzle velocity, I'd probably be more concerned with the Rounds Per Second, at stock with a 7.4 Lipo can give about 15 rps, with a 11.1 Lipo in excess of 22 rps. #Airshot ammo modThere is a mod for the XCR that allows me to remove the fake gas tube that is just above the gas blowback to provide me with lots of room to stuff in there as well. I will most likely be using a PEQ box or bag for the arduino. Or drill a through hole, across the barrel ? Maybe not. The opto sensor should be located at the end of the gun barrel. For me, I shop localy at It only a few minutes drive ( on Steeles Ave W or the 401 ) Or others location online DigiKey Here a link. I don't know where you live ( I am assuming USA ). That should be under $20 ( US ? Can ? ) The most expensive is the 3 position swtich. Sensor : use a phototransistor, a small light bulb or a small laser ( from a laser pen ), a 3 position switch ( for ammo selection ), a push button ( to reset the counter ), resistors, a 74LS47 for the display, some transistors, a encoder chip 74LS147, some PCB board. I am on somewhat of a budget, and would like to keep this modification under $20 Here a post I did and a schematic Arduino Forum My program and schematic only use 2 digits, but 3 is no problem, just and another PNP transistor and a base resistor. Thanks!įor those interested, this is the basic concept of how the internals of the airsoft gun work: #Airshot ammo how toI may need some help with understanding on how to drive the 3 digit LED display.ĭo the sensors provide serial feedback? Anyhow, some guidance here would be much appreciated, or even some sample work that I can look at. The counter and reset stuff I should be ok. To me, it's whatever is cheaper really.Īnyhow, what sort of sensors would I need? I shop primarily at Seeed Studio, but do not know where to begin with this. The accuracy of the count is not too important, but I would have to say that the later is the most reliable because the airsoft gun may shoot blanks sometimes. Some people have put a pedometer like sensor on the trigger or gas blowback while some have put some sort of light sensor at the end of the barrel where the pellet exits. ![]() Where the solution differs is in how I would sense or account for each launched pellet. 30 for low cap, 130 for mid cap, and 400+ for high cap). One to reset the ammo counter display (perhaps hook it up somehow to the mag release) and another button to toggle between different mag capacities (e.g. In addition to what I have already, I envision I will need two buttons/switches. I am on somewhat of a budget, and would like to keep this modification under $20 (I have an Arduino Duemilanove and a 0.36" 7 Segment Super Red LED Display 3 Digit Anode already). I've done some searching online for these, and there are several ways to going about it, but I would like some advice from you guys as to which route would be most feasible. Hello there, I am looking at creating an ammo counter for my airsoft gun. ![]()
