JCheeseright Posted August 10, 2016 Report Share Posted August 10, 2016 That's not true. CAG has and does use the MK18. Yes they also use the HK416 and prefer it over the M4. They have the SCAR-H at their disposal. They recently stopped using the Glock 22 and use the Glock 17 and Glock 19 with the Glock 19 getting more use. Are we suppose to believe that the only weapon CAG uses is the HK416. That's simply not true and as an elite Special Forces unit, they can get and use whatever weapon or gear they want. Why would you use a direct impingement SBR like the Mk18 / CQBR when you can use the HK416? Obviously they have a huge arsenal of weapons available to them but I find it hugely unlikely they'd have two 5.56mm rifles with the exact same barrel length just 'because'. The HK416 is a better platform and the only 5.56 rifle CAG have been photographed with for about 10 years. Even when they were using the M4 it wasn't in 10.3" format, they were almost exclusively using 14.5" barrels with GG&G rails, but that's ANCIENT history now, like pre 2004. The Mk18 / CQBR is not a correct weapon for CAG. For MARSOC, Army SF, AFSOC, SEALs, Rangers etc it's accurate, but CAG don't use it, haven't done for over a decade. Link to post Share on other sites
Alias1983 Posted August 11, 2016 Report Share Posted August 11, 2016 DI vs piston is an age old debate and it's down to preference. Either the dirt gets in the action(1 cleaning location) or all over the handguard(2 locations, you need to clean the piston). (DI)The heat stays in the action and not in the handguard. Barrels blow out before the gas tube ever will. Piston guns of the shelf are easier to suppress but a proper gas block eliminates this issue. Link to post Share on other sites
CaptCalvin Posted August 11, 2016 Report Share Posted August 11, 2016 To be fair dirty piston and handguard doesn't affect functioning of a gun as much as a dirty action. And also a suppressed piston gun doesn't blow eye stinging gas back into the shooter's face like a DI gun without special parts would. But, with all other variables being constant a DI gun does have more accuracy potential than a piston gun. A gas tube doesn't affect barrel harmonics as much as heavier moving piston spring oprod parts and stuff. Oh and of course, it's heavier. Link to post Share on other sites

CaptCalvin Posted August 11, 2016 Report Share Posted August 11, 2016 Well the gas has to go somewhere, and most of it ain't through the front. Link to post Share on other sites
Alias1983 Posted August 11, 2016 Report Share Posted August 11, 2016 It's all in the gas adjustment, delaying the "blowback" sends more gas down the barrel. Gas port size. Suppressor carrier. The charging handle has gaps that causes issues. Throwing a can on a full gassed system will give you gas face and a rough running system. Build the system for a can and you won't get gas face.

CaptCalvin Posted August 11, 2016 Report Share Posted August 11, 2016 I did say you will get gas in the face with a standard setup. With DI you'd have to build a rifle around a suppressor. When you've built a rifle to run smoothly on a suppressor once you take the suppressor off you end up with a undergassed rifle. There are of course adjustable systems out there, but in general it's not going to be a simple flip of a switch like on piston systems as adjustable gas blocks come mostly with fine adjustments to accommodate the relative sensitive nature of DI. It can be done and done well, but it's just much less fuss with a piston gun. Link to post Share on other sites

Point of impact and all that, I'm currently planning a build for an internally suppressed setup. This way I only have to pay for 1 tax stamp(can). Some gas blocks are as simple as "flipping a switch", the suppressor bolt for instance, this is a flip a switch setup. But you need to know what your are doing, you need to research and measure.

CaptCalvin Posted August 12, 2016 Report Share Posted August 12, 2016 It's more of a take the gun apart, flip a switch set up, and put back together setup. Bottom line is in no way is suppressing a DI gun un-viable, but less fuss would be had with supressing a piston gun. And I would constantly take the cans on and off. I would shoot with them on for my own enjoyment, but if I am training for or anticipate the need to use the guns for life and death situations the cans are nowhere near my guns. Caught with one of these(or any NFA item) in an incident and you've dug yourself a hole. Link to post Share on other sites

Let this thread go back to its original topic Piston/DI has no bearing on these tests. It doesn't make it any safer. A piston AR assuming all other aspects being constant would've blown up just the same when fired underwater. Also the fact that in the HK test the M4 spectacularly suffered irreparable damage on only the first round fired out of the water whereas the AR in the second video fired 2 rounds UNDERWATER before a failure with easily repairable damage just shows how rigged the HK test was. The Navy have made small modifications to their MK18s to prevent these failures and have been over the beaching with DI guns for decades with no issues. Link to post Share on other sites

paranoiddroid Posted August 21, 2016 Report Share Posted August 21, 2016 I know the real one isn't quite Stanag compliant even though most metal box magazines for the m16 and other Stanag guns fit hence the e-mag same with the IAR thing. Alias I'd disagree assault rifle is a recognised class of weapons and has been since 1930ish denoting a select fire firearm with a carbine to short rifle (sub 20") setup to fire n intermediate cartridge. Assault weapon is an awful made up term created by Sarah Brady, Satan with bad hair herself Nancy Pelosi and people like senator McCarthy when they whipped the press into a frenzy with a nonsensical law which gave us such gems as 'the shoulder thing that goes up' and a horrible horrible thing called the y-comp which makes a 5.56 feel like your eardrums are bursting even with high end plugs and muffs. It does clear indoor ranges well so you can get some private time shooting though. Link to post Share on other sites
aac Posted August 21, 2016 Report Share Posted August 21, 2016 I just ordered a G&G Combat Machine M4 CQB which I plan on making into a MK18 Mod 0. I'm more interested in accessories for MK18 Mod 0 that are still in use as of present day, not what they were originally configured for when the program first started. Considering that the primary users of the MK18 weapon system are special forces, this gives me leeway as special forces often modify their weapons with whatever accessories they want. I definitely want the KAC RIS. I was thinking of either the Vltor IMOD stock or Crane stock in case I decide to wire the AEG to the rear with a MOSFET, which I will most likely do in the future. I'm also going with a Tango Down pistol grip. What other, present day accessories that were not originally issued with the MK18 Mod 0, are being used by special forces for their MK18 Mod 0? Funny how the Mk18- discussion always escalate (I quoted @Special Ops" initial post just to compare) Link to post Share on other sites

NonEx Posted August 22, 2016 Report Share Posted August 22, 2016 FYI I am pretty sure I recall seeing an updated HK416 at ShotShow a few years ago where one of the changes was the magazine well design so that it was compatible with PMAGs out of the box. Don't think airsoft versions have followed that though but since this thread seems to be more about RS than airsoft I thought I would add that Link to post Share on other sites
abbadon101 Posted August 22, 2016 Report Share Posted August 22, 2016 The brown one? Yeah they changed the lower so its silhouette is nearly identical to the standard AR15 one now. Yeah its a shame the thread got derailed. Link to post Share on other sites
