Ragitsu Posted July 29, 2015 Report Share Posted July 29, 2015 Well hey...at least you can claim your suppressor is over triple the length of the gun's barrel itself whenever you use that chopped down assault rifle/carbine/handgun with the mumps.

wcw43921 Posted July 29, 2015 Report Share Posted July 29, 2015 AR-15 with 2" barrel (not a typo) I could see something like that in the hands of street thugs, but not as a professional's weapon. Quote Link to comment Share on other sites More sharing options...
Zeropoint Posted July 29, 2015 Report Share Posted July 29, 2015 The article about it on The Firearm Blog seemed to indicate that this weapon exists for the sole purpose of demonstrating that the AR gas system DOES, in fact, work just fine with very short barrels. Also notice that the barrel length is less than the overall length of a 5.56 NATO cartridge and you can see the tip of the bullet poking out the muzzle.

megaplayboy Posted August 3, 2015 Report Share Posted August 3, 2015 The caliber of the upper barrel should probably be .40 or 10mm Auto or better to simulate the stopping power of the M41, but otherwise looks pretty kewl. Remjin 1 Quote Link to comment Share on other sites More sharing options...
Old Man Posted August 4, 2015 Report Share Posted August 4, 2015 The movie prop was built on a Thompson M1A1 and a Remington 870 with a SPAS-12 grip. It looks like that's what they've done here. In-universe the M41A fired 10mm explosive tipped, caseless, light armor piercing rounds. Hard to simulate that level of stopping power with anything current.

gewing Posted August 4, 2015 Report Share Posted August 4, 2015 .50 beowulf, in an AR10 length action, so you can probably seat the Multipurpose APHE round from the Mk211 and still fit it in the magazine. Loaded to the highest velocity appropriate... Though I think that projectile may not detonate reliably at under 1100 fps or some such, so it would be questionable... The same case, or even a .308 case could be loaded with a 10mm projectile, but the APHE is not available in that caliber, afaik. There are some interesting military loads for the .338 Lapua and .338 Norma, so those bullets could be loaded. At about 300 grains, Depending on which action and magazine were chosen, and which case was used, it might be possible to get 2200 fps or possibly even more, but... Using the Russian 30mm grenades would, realistically, be more practical than the US/Nato 40mm. Longer, but narrower and longer effective range. The 12 ga explosive shells are of limited effectiveness... Quote Link to comment Share on other sites More sharing options...
megaplayboy Posted August 4, 2015 Report Share Posted August 4, 2015 Or 25mm grenades, which exist and aren't too much larger than 12 gauge rounds. Quote Link to comment Share on other sites More sharing options...
gewing Posted August 5, 2015 Report Share Posted August 5, 2015 Or 25mm grenades, which exist and aren't too much larger than 12 gauge rounds. True. One thing I did not mention is that the magazine capacity could NOT match the movie with anything more than MAYBE 10mm Auto, and I don't think even then. It is a very impressive round, and there was a magnum version... Quote Link to comment Share on other sites More sharing options...
freakboy6117 Posted August 6, 2015 Report Share Posted August 6, 2015 yeah the downside of not having caseless ammunition lol Quote Link to comment Share on other sites More sharing options...
gewing Posted August 6, 2015 Report Share Posted August 6, 2015 Even caseless would probably be difficult to fit iirc 100 in a reasonable size, at a 10mm diameter. Quote Link to comment Share on other sites More sharing options...
freakboy6117 Posted August 6, 2015 Report Share Posted August 6, 2015 thought you guys might find this interesting a internally supressed urban sniper rifle can use sub or super sonic .300 ammo designed for taking out dogs cameras and other nuisances for stealthy urban operator . video shows just how quiet it is the bolt is louder than the subsonic rounds.

Zeropoint Posted August 6, 2015 Report Share Posted August 6, 2015 Neat stuff. I sure wish they'd drop the tangle of red tape and legal landmines around suppressors/silencers here in the US. They're good for reducing noise pollution and hearing damage. Quote Link to comment Share on other sites More sharing options...

Old Man Posted August 7, 2015 Report Share Posted August 7, 2015 Even caseless would probably be difficult to fit iirc 100 in a reasonable size, at a 10mm diameter. I'm thinking single stack. Quote Link to comment Share on other sites More sharing options...
Zeropoint Posted August 7, 2015 Report Share Posted August 7, 2015 On the pulse rifle magazine, I was thinking a "casket magazine" or some similar quad-stack arrangement. Edit: Nope, it just won't work. It's geometrically impossible to get 100 rounds of anything with a 10mm diameter into a magazine with that cross-section. 100 round casket magazines are available for the AR platform, but they're about three times the size of the pulse rifle magazine.

Old Man Posted August 8, 2015 Report Share Posted August 8, 2015 Did you consider a short round and forward and rear stacks? The reason I suggested single stack is that one hundred 10mm rounds would require a magazine at least 1000mm long. Remjin 1 Quote Link to comment Share on other sites More sharing options...
gewing Posted August 9, 2015 Report Share Posted August 9, 2015 If a Quad stack were used, it would probably be reasonable to put 48-60 cartridges in it, if you used the 10mm Pistol round or even the "Magnum" version that never really saw much use. I think I only saw it in one of the AMT Automag pistols, maybe the Automag 4 (a quick google says I was right) but It never really went anywhere. I found an article on it, that is interesting. 200 grain bullets at 1500fps out of an 8 3/8ths inch barreled semi auto. I suspect it would well do 1700+ out of a Carbine length barrel as used on the Gun in question. Just for reference, here is the article. http://www.sixguns.com/tests/tt10mag.htm Taffin writes a lot of good information on loading ammunition, for Handguns Mostly. If you are actually interested in guns and shooting, I recommend browsing his site. Quote Link to comment Share on other sites More sharing options...

megaplayboy Posted August 10, 2015 Report Share Posted August 10, 2015 Well, if you combined the tranq cartridge with the propellant, you could maybe do it. Quote Link to comment Share on other sites More sharing options...
