swatti Posted April 16, 2015 Report Share Posted April 16, 2015 If im not mistaken, you need a permit for blanks and even primers in here. CO2 would be optimal, you need very little of it as it expands faster then green/red-gas Link to post Share on other sites
gisburn20 Posted April 16, 2015 Report Share Posted April 16, 2015 Legal requirements for blanks and primers vary, but in the UK you can buy blanks from most gunsmiths with no paperwork, and mail order primers from about £8 per hundred easily enough. Not suitable for every country to be sure, but no worries in the UK. CO2 over here is £0.50-£0.90 per capsule. Jim. Link to post Share on other sites
Korppi Posted April 16, 2015 Report Share Posted April 16, 2015 Yes but one can refill co2 like any other gas with paintball tank of varied sizes from 88g to 700g etc using same kind of nozzle and fill valve as any gas gun/nade etc. That being said, I'd really like to have those pyros and blank firers available here. The mortar looks so cool. I'm surprised that there is no 40mm pyros (other than tag)..? Link to post Share on other sites
gisburn20 Posted April 16, 2015 Report Share Posted April 16, 2015 800psi inside a grenade to throw at people? Thats going to have to be solid steel and built like a tank. People have been launching pyro (illegally ) from 40mm moscarts for at least the last 10years at least TAG is legal (ish) but very expensive, i did like the look of the spring powered m203 launcher for mk5 pyro but some sites have banned it.

Korppi Posted April 16, 2015 Report Share Posted April 16, 2015 Why not? The internal reservoir can be made smaller than with gg etc then, focusing on the bb expelling and cushion. Link to post Share on other sites

The mortar looks so cool. I'm surprised that there is no 40mm pyros (other than tag)..? Yes, there are. Check out my P.M.O.G. pyro/chalk rounds: https://youtu.be/DEYj-hF2cD0?t=15s The pyros in P.M.O.G. rounds are more legal than those in TAG ones in US. There are only 0.008 mg of silver fulminate in the snappers as compared to 85 mg flash powder in the TAG rounds (U.S. regulations restrict pyrotechnic content to be less than 50mg in commercial fireworks: https://www.atf.gov/publications/factsheets/factsheet-illegal-explosives-devices.html). UK's regulations are more lenient - you can go upward to 200mg - hence TAG pyro rounds are OK in UK. You'll have to build your own P.M.O.G., though.

dEFCONairsoft Posted May 26, 2015 Report Share Posted May 26, 2015 Those Thunder B's are a cheap solution for a bang with projectiles https://www.youtube.com/watch?v=2CxG1VItqMM The kit is about a tenner on silco.co.uk, spare cases about 50p each plus the cost of a new CO2 bulb each time Link to post Share on other sites
hitmanNo2 Posted May 26, 2015 Report Share Posted May 26, 2015 Is there a way to reduce the rupture time on the Thunder Bs though? I would want around 2/3 seconds rather than 7 or so. Link to post Share on other sites
dEFCONairsoft Posted May 26, 2015 Report Share Posted May 26, 2015 yeah, just lightly score the surface to create a weakness - this makes it detonate quicker. Also putting BBs in reduces internal volume and makes pressure build up faster leading to quick detonations as seen in the video Link to post Share on other sites
hitmanNo2 Posted May 26, 2015 Report Share Posted May 26, 2015 I'd read about putting BBs in to reduce volume. Would scoring the surface not compromise the loudness of the bang at all? Link to post Share on other sites
dEFCONairsoft Posted May 26, 2015 Report Share Posted May 26, 2015 it doesnt 'seem' to but if you score it too deeply you'll hear it go bang quickly then continue to hear gas coming out for a few seconds afterwards - obviously this is a waste of gas which theoretically would make the bang louder if it all came out at once. The trick is just gently mark a cross on the side with a blade to help it along without gauging too deep Link to post Share on other sites
hitmanNo2 Posted May 26, 2015 Report Share Posted May 26, 2015 I gather these are pretty loud anyway so a slight reduction wouldn't be that big of a deal I suppose. Link to post Share on other sites
dEFCONairsoft Posted May 26, 2015 Report Share Posted May 26, 2015 nah, they're still plenty loud enough! Link to post Share on other sites
scorch Posted May 28, 2015 Report Share Posted May 28, 2015 Isn't there a method for speeding up the detonation by putting a spacer under the CO2 cart to deepen the puncture and widen the holes in the cylinder to allow the gas to escape faster. Link to post Share on other sites
dEFCONairsoft Posted May 28, 2015 Report Share Posted May 28, 2015 Hmm, that may well work as the spike is wider further up the shaft (oooer!). Will try it later with some pennies in the tube. Link to post Share on other sites
scorch Posted May 28, 2015 Report Share Posted May 28, 2015 Pennies in the tube is what the guy on YouTube did IIRC. Link to post Share on other sites
T3CH Posted May 28, 2015 Report Share Posted May 28, 2015 It's what I used to do along with scoring the sides. Link to post Share on other sites
Imperator Posted June 2, 2015 Report Share Posted June 2, 2015 Found the impact grenades from the video on sale at a Spanish website. They are retailing for €122...http://www.snipersairsoft.es/zoxna-granada-de-impacto-negra-p-3078.htmlWay too steep for me. Link to post Share on other sites
sir naggedalot Posted March 26, 2016 Report Share Posted March 26, 2016 The Prohibition specifies "not for pyrotechnic purposes" though, which is probably why they're ok, seeing as we throw smokes and bangs for the pyrotechnic effect of smoke and/or bang. If I recall correctly the instructions on smokes and flash bangs both state that they should be both dropped after being striked/lit! Nowhere does it mention throwing after ignition Link to post Share on other sites
