bladerunner168 Posted May 28, 2013 Report Share Posted May 28, 2013 uscmCorps - any idea when the Rainier Arms charging handle will be out for the KWA/KSC platform? Quote Link to post Share on other sites
uscmCorps Posted May 28, 2013 Report Share Posted May 28, 2013 It should be really soon. The packaging artwork is already prepared. Quote Link to post Share on other sites

Inq Eisenhorn Posted June 20, 2013 Report Share Posted June 20, 2013 Do the latest PTR have the three piece uppers? Quote Link to post Share on other sites
uscmCorps Posted June 20, 2013 Report Share Posted June 20, 2013 They do. However, they also have functional bolt catch release when racking the gun's charging handle. Quote Link to post Share on other sites
Stuey Posted June 20, 2013 Report Share Posted June 20, 2013 Ah so you guys adjusted the design? That's cool Quote Link to post Share on other sites
christhesecond Posted June 28, 2013 Report Share Posted June 28, 2013 Quick question for you guys: http://www.gggaz.com/ar-15-free-float-tactical-forearm.html Would that fit a ptr without mods? Quote Link to post Share on other sites
bladerunner168 Posted June 28, 2013 Report Share Posted June 28, 2013 Is there a specific barrel nut that comes with this RIS? If yes, then all you need is brute strength to get it on (assuming you don't want to re-thread). Quote Link to post Share on other sites
christhesecond Posted June 29, 2013 Report Share Posted June 29, 2013 No it doesn't. It says it clamps on to the barrel but so I assume that means the existing one. Quote Link to post Share on other sites
bladerunner168 Posted June 29, 2013 Report Share Posted June 29, 2013 I remember someone on the KWA forums saying that the 1st gen of RS Troy rails did not attach itself properly to the LM4 barrel nut so there's a chancing element here. Quote Link to post Share on other sites
emp3ror86 Posted June 30, 2013 Report Share Posted June 30, 2013 Without serious modification to the barrel nut it is most likely that it will not fit. I installed a Troy Alpha once, barrel nut had to be filed a lot. Outcome was not perfect as the rail could not be secured perfectly. Quote Link to post Share on other sites
hwagan Posted July 1, 2013 Report Share Posted July 1, 2013 I had an R/S Samson rail fit absolutely fine on a KWA LM4 barrel nut - Took a light tap to one half of the thermal bushing to get it to seat, but it mounted without issue. Quote Link to post Share on other sites
DeltaZero Posted July 23, 2013 Report Share Posted July 23, 2013 Hi guys! I've recently acquired an LM4 finally and have a quick question to ask you! I want to change the barrel down to a CQBR, I heard the OEM outer barrel is a two part to take it down to a 10" but I don't want to start mangling the barrel if that isn't the case! Can someone please confirm this for me? I can see what looks like a join but im not sure. Also if it is a two part, whats the easiest way to get them separate? Cheers!

It is a two part barrel, but in my case, it was exceptionally difficult to remove. It was threadlocked on, and I ended up ruining the extension despite wrapping it in electrical tape when using pliers... Might be easier for you, or heating the barrel could work. Either way, once it's removed you'll also need to replace or cut down the inner barrel. Unfortunately, I can't remember the thread direction off the top of my head... I think it's negative, but I can't confirm that so find out first! Quote Link to post Share on other sites
uscmCorps Posted July 23, 2013 Report Share Posted July 23, 2013 On the 14.5" LM4 carbine, the extension is about 5" in length. So once you remove the extension, the outer barrel is about 9.5" In length. The seam between outer barrel and the extension is normally concealed by the fixed front sight post. So if you want a 10.5" outer barrel you will need to cut down (or replace) the inner barrel, and swap the 5" carbine extension for a 1" long 14mm counterclockwise extension. To get the barrel extension off, use a heat gun. 1 Quote Link to post Share on other sites
DeltaZero Posted July 23, 2013 Report Share Posted July 23, 2013 Fantastic thanks chaps. Is there one piece CQBR outerbarrel out there available? And also how do I get the gas rod out? I'm presuming its just friction fitted, seems pretty tight to me! Quote Link to post Share on other sites
uscmCorps Posted July 23, 2013 Report Share Posted July 23, 2013 I don't know if any manufacturer currently makes a one piece KWA/KSC 10.5" outer barrel. The LM4 CQBR's outer barrel is also made up of the barrel plus the 1" extension. The gas rod is pinned into the fixed front sight like it should be on a real AR from what I recall.

WTF?Shane Posted July 23, 2013 Report Share Posted July 23, 2013 It was posted in the KWA forums. Guarder made aftermarket outer barrels for the KSC/KWA. Quote Link to post Share on other sites

Thanks mate, I've got the pin out from the front sight. I was worried it could be attached at the receiver. Must just need a bit of a tug! Quote Link to post Share on other sites
uscmCorps Posted July 24, 2013 Report Share Posted July 24, 2013 Nah. It's just press fitted into the upper receiver. If you twist the front sight a few degrees clockwise and counter clockwise it should slide right out with a little effort. And as Shane pointed out (thanks Shane), Guarder (and I think DYTac too at one point) makes aftermarket CQB length outer barrels. When looking for aftermarket outer barrels, just make sure it is KSC/KWA GBBR compatible (most barrels simply just say "KSC compatible" since that's more common in Asia where the aftermarket manufacturers are based out of). That said, it's probably cheaper to just swap barrel extensions (IMO). Quote Link to post Share on other sites
emp3ror86 Posted July 24, 2013 Report Share Posted July 24, 2013 Z-Parts also makes barrels for the ksc/kwa platform. Quote Link to post Share on other sites
