akiraspeedstar Posted January 14, 2013 Report Share Posted January 14, 2013 You could email or call them, I have a complete secondary bolt from them. One shoots 350fps for CQB and the other 400fps for field use. Quote Link to post Share on other sites
ollie_ty Posted January 14, 2013 Report Share Posted January 14, 2013 I email KWA about parts all the time. Its really easy, and they'll keep your details on file so the next time you order something its even faster! Quote Link to post Share on other sites

One shoots 350fps for CQB and the other 400fps for field use. To clarify, the 350 FPS bolt was one you worked on, right? When you got it from KWA it was identical in performance and all?

akiraspeedstar Posted January 14, 2013 Report Share Posted January 14, 2013 That's correct, I modified the bolt to operate at 350fps. Quote Link to post Share on other sites
Stuey Posted January 14, 2013 Report Share Posted January 14, 2013 Closed bolt or open? Also GG or Co2? Open bolt, propane with the new gen 2 mags. He did try the CO2 mags but they leaked and broke his bolt so he's gone back to propane which works just fine, even when it's snowing. Quote Link to post Share on other sites
emp3ror86 Posted January 15, 2013 Report Share Posted January 15, 2013 (edited) For winter operation: have you guys tried cutting recoil springs? Edit: I wonder why the why the LM4 version of the lightweight bolt is not released yet when they are made in the same factory. But I also do not understand why the US market had to wait half a year for the CQBR outer barrel which was in production a year before the release of the LM4.

But I also do not understand why the US market had to wait half a year for the CQBR outer barrel which was in production a year before the release of the LM4. The wait more then likely was just so KWA could spread around their releases for the year instead of having a giant gap between the LM4 and the Vector. My LM4 is still having double feed problems on full auto. I havent been able to sort them out and KWA has been out of stock on all the parts I wanted to try replacing. So mine is more or less stuck on semi auto. It suits my playstyle though so its not the end of the world I suppose. Quote Link to post Share on other sites
emp3ror86 Posted January 17, 2013 Report Share Posted January 17, 2013 I understand the financial and business decisions behind their actions yet I do not agree with it. You need to provide more information about the problem. What type of magazines do you use? What quality BB and what type of propellant? Do you see any damage or deformation on your magazine feed lips, nozzle or on the feed ramp of the receiver? Quote Link to post Share on other sites
akiraspeedstar Posted January 19, 2013 Report Share Posted January 19, 2013 I was bored so I polished the face of my Guarder steel trigger to a mirror finish. The pull is EXTREMELY smooth and the best part is if you pull the trigger right before the breaking point and release, it'll reset. I'll let you guys know if this causes any damage. Also my trigger, disconnector, and hammer have no signs of damage after my last trigger job. Quote Link to post Share on other sites
WTF?Shane Posted January 19, 2013 Report Share Posted January 19, 2013 I was thinking of doing the same to mine, but haven't got around to taking it apart. Quote Link to post Share on other sites
emp3ror86 Posted January 19, 2013 Report Share Posted January 19, 2013 That idea sounds really good. Akira, could you show a picture about the polished part, please? Quote Link to post Share on other sites
WTF?Shane Posted January 19, 2013 Report Share Posted January 19, 2013 That idea sounds really good. Akira, could you show a picture about the polished part, please? emp3ror86, I believe it is the same spot as the AR-15 triggers. You would polish the very front face of the trigger bar and where it contacts on the hammer, (sorry for lack of nomenclature) the little notch face on the bottom.

hwagan Posted February 4, 2013 Report Share Posted February 4, 2013 I'd imagine it's like a normal bean, only more red. 1 Quote Link to post Share on other sites

hwagan Posted February 4, 2013 Report Share Posted February 4, 2013 Awwww shucks <3 Back on topic, does anyone use anything heavier than a .3 in their LM4? I've bought some Madbull .4's, but the standard bucking isn't really providing enough lift, and I feel I could get another decent chunk of useful range out of it... If anyone runs .36's or .4's, any suggestions? Quote Link to post Share on other sites
WhatAreYouBuyen Posted February 4, 2013 Report Share Posted February 4, 2013 I use KWA .3's , the fields I play at aren't that huge, maybe thats why I'm already satisfied with the range. The red bean is an attachment to the gun that gives infinite range Quote Link to post Share on other sites
hwagan Posted February 4, 2013 Report Share Posted February 4, 2013 See I've been using .3's, but frankly at my local site I need something with a bit more wallop... .4's are travelling a decent distance, but with no upward flick. I imagine with a bit more hop I'd get a decent bit more range, and with excellent accuracy 'n all. Wondering if another bucking might not be a bad idea. Failing that, I may just invest in a red bean... Quote Link to post Share on other sites
John_234 Posted February 4, 2013 Report Share Posted February 4, 2013 From the outset I've aimed at setting up my own LM4 to be more of a CQB weapon. I think that's because I'm still hoping they make an LM4 system AR-10 that I can go nuts with. Quote Link to post Share on other sites
akiraspeedstar Posted February 5, 2013 Report Share Posted February 5, 2013 Nice gun, though I'll never understand the rail covers on the upper receiver thing. Quote Link to post Share on other sites
