Thanks for your interest. I've got to give my reviewers more time to find if there are any problems. In fact, I'm glad I went through the beta-testing process with PMOG 2.3. My reviewers reported quite a few problems, and I'd imagine people would not be happy if they found that out after purchasing.

Booligan's preliminary tests of PMOG 2.4 seemed to be pretty favorable. He will be doing more in-depth reviews in the following weeks. If all goes well, you should be seeing it on the market before X'mas.

well, r/cl is finally ready for a model for printing, and here's the basic shape:


the general idea was to enlarge the housing to accommodate a milsim labs grenade. this gives it use in both paintball and airsoft. it will be fired from a 2" rifled PVC pipe, and will have true grenade projection capability, with a wide area affect along with hit marking for tanks.

Someone brings up a good discussion point on developing a P.M.O.G. Rocket Projectile for Deepfire Rocket Shell or Madbull XM995 Rocket Shell. The first that should be considered is the weight of the projectile because of the bigger size. Based on a model of injury potentials of non-lethal weaponry, I estimated a practical Airsoft projectile cannot weigh more than 75 grams to stay within less-lethal limitations.(Lyon, 1999) I would actually recommend around 30 grams so that it hits like a BB. That being said, with the use of light weight materials, reaching the weight goal may be possible. Another consideration is the shell. Deepfire and Madbull developed the elongated specialty shells for two reasons: the rocket base needs to be hollow to keep most of the weight forward for stability, and the shell exhaust valve needs to be as close to the rocket tip to provide maximum thrust. However, this also makes the shell more expensive - $60 compared to $30 G&P Projectile Cap Shell on Evike. Another problem with the elongated shell is the increased friction between the shell and the projectile, which may reduce the efficiency of the system.

For rocket-shape Airsoft projectiles, I think Milsimlab's M29 is more efficient and effective (https://www.facebook.com/MilSimLabs). M29 has be shown to be capable of reaching 200+ feet with just green gas (http://youtu.be/Ad2LbtAaK9w). The new version of M29 even has a cut-out at the tip for chalk-fillings, snaps, or paintballs. The only drawback is the extra step of loading the projectile since M29 cannot be attached to shells easily.

P.M.O.G. projectiles are designed to emulate the real-steel 40mm grenades, which means they can be carried and loaded easily as shown in my earlier video: http://youtu.be/tFKYeKn1ubM?t=14s. In my opinion, P.M.O.G. is best suited for clearing out strong points in MOUT with rapid fire, while M29 for taking out vehicles at longer distance.

Many thanks to "Keeper / NepaAirsoft" for an excellent in-depth review of P.M.O.G. Airsoft / paintball 40mm Projectiles. He showed it's possible to hit a window-size target repeatedly at 60 feet if you put in consistent amount of gas in your shell. Notice that he was using the combination of S-Thunder High-Power Shell and launcher pistol, and he came up with an interesting way to load the ammunition.

Also, he mentioned that green gas did not provide enough power to propel the projectile, which I believe is mainly due to the the shell he was using. The P.M.O.G. was designed to fit on G&P Projectile Cap Shell, and there's very little space between the gas port on the G&P shell and the P.M.O.G. In contrast, there's about an inch or two with S-Thunder High-Power Shell and the P.M.O.G. The empty space translates to more space to fill the air in and less propelling force. Even so, I strongly recommend using CO2 because it is more powerful and does not get affected by the cold much.

Lastly, I acknowledge the problem with the sponge tip coming off with the review samples. I believe if I put on Gorilla glue instead of hot glue, it should stay in place. I'll make sure it does so for the production model.

With 500 psi in my G&P Projectile Cap Grenade Shells, I got 145.1, 145.9, and 148.4 fps: https://www.facebook.com/pmogarmory/...85316828331751

Speaking of M203 leaf sight, I did the angle measurement with a digital lnclinometer a while back (please see the markings in the picture below, from bottom to top):

Red line: 0 degree
1: 5 degree
1.5: 9 degree
2: 14 degree
2.5: 19 degree
3: 21 degree

I just sent the instructions of making my creation - P.M.O.G. Airsoft 40mm Projectiles to selected Airsoft small business owners (people whom I owe favor to). I thought about selling them myself, but U.S. business regulations forbid me from running my own business, or even getting paid without having the employer complete tons of paperwork. In any case, what I really care about is getting as many players to use P.M.O.G. at national OP this year. I will let you know as soon as they accept my proposal.

Here's a video of P.M.O.G. Airsoft 40mm Projectiles promotion and proposal: http://youtu.be/zk2dMTq0QYg

Hey quick question: has anyone tried the hpa tapped 203 shell yet that remains in the launcher?

i'm curious if that actually works since i would assume the constant flow of gas would hold the grenade valve open

Here you go - detailed instruction courtesy of Crew Chief's Custom: http://www.crewchiefpb.com/main/inde...id=34&Itemid=1

You need a 3-way Push Button Valve to disrupt the flow of air to the shell.

Yeah that looks exactly like the internals of a standard airsoft m203, my question was pertaining to how the valve reacts when you pull the trigger, i'm guessing it just continues to dump gas unless the return spring is strong enough to overcome the pressure

the site looks promising though, i can probably improve on that trigger, I was more hoping for someone that has done it to an eglm
once my kar98 project is done this will likely be my next one.

Due to my international student status and low profit margin, I decide to make the P.M.O.G. Making Instructions open to public. Make your own P.M.O.G.! The initial material costs will be around US$ 150: https://drive.google.com/open?id=0Bx...UUk&authuser=0, but the material cost for each round is about US$2 once you set everything up. As for labor time, one P.M.O.G. projectile takes about 15 minutes to make if you make a set of six in one session.

The P.M.O.G. can be easily made with household and commercial products. There are three major steps in making them:
1. Molding: http://youtu.be/1-7sR3eAqMs
2. Casting: http://youtu.be/wmCgwCll6dM
3. Assembling: http://youtu.be/qtHipeqYoNc

Here are some supporting documents:
1. Transcripts of the making instructions: https://drive.google.com/open?id=0Bx...MVk&authuser=0
2. P.M.O.G. Making Tool and Material List (good for making 27 rounds): https://drive.google.com/open?id=0Bx...UUk&authuser=0
3. P.M.O.G. Making Tool and Material List (good for making 252 rounds): https://drive.google.com/open?id=0Bx...ajQ&authuser=0
4. P.M.O.G. User Manual: https://drive.google.com/open?id=0Bx...UG8&authuser=0

Here is the playlist of P.M.O.G. Projectiles including development, safety tests, and reviews: https://www.youtube.com/playlist?lis...r6AxNvYoxzOgKC

Be advised, though. As you make your own P.M.O.G. Projectiles, they might NOT be accepted by field owners or event producers due to liability. I have done quite a lot of safety testing myself and I think they are safe to use with 30 ft MED. But you shall not hold me responsible in court since I do NOT make or sell them. Safety test videos:
1. Safety test 1: https://youtu.be/FocXStzGLA4
2. Safety test 2:https://youtu.be/SNlobal6bqU
3. Vehicle safety: https://youtu.be/5db0Begh-RQ

It is not a standard M203 shell. It is a S-Thunder "Loudest", Madbull PB4, or Eagle Force Multi-purpose shell, which can reset by itself most of the time when air supply is cut off. I am not aware of any other makes that have rear-mounted valve and are self-resetting.

I did show a concept drawing of modified EGLM in a previous post. I'm having a second thought about the position of the 3-way valve. I think if you add a remote line to the 3-way valve and mount it on your vest, it should be easier to reset the shell.

I dont think a 3 way is necessary, unless my pneumatics are rusty, a 3 way valve is a Y connection, you just want an on/off push valve that defaults to off.

as for self resetting shells, if you're cutting off pressure I dont think, again, its too much of an issue, most shells require that you either press the button an extra time (an extra trigger pull) or loosen the shell (which is only because the valve is too tight in the body) by spacing out the valve body with an O ring so it doesn't pop open so harshly just about any shell will self reset.

I think you put the valve sideways, right off of the shell, so you have a pushbutton on the side of the launcher you can press after loading the next round. I was thinking of simply drilling and tapping the button on the valve so if worse comes to worse you could "force" it to reset by pressing the trigger forward.

if you really wanted you could reposition the shell deeper into the launcher too, i'd suggest measuring the volumn of the chamber that holds gas in the shell and mathing out the volumn of the launch tube, I have a feeling that these smaller shells are hurting velocity by not keeping a high enough gas volume, if so machining a simple threaded cap for the end that doesn't interfere with the PMOG might be best
