Well, here it is, gas gun fans.  A battle for the ages.  I have thrown the KWA LM4 PTR, King Arms Colt M4A1 & the G&P WOC M4 Kit into the ring together to see which one(s) will make it out alive.

 Here on the Pyramyd Airsoft Blog, I will cover the good, the bad and the hideously ugly of these three rifles.  I will freely admit that these are not the only gas blowback M4 rifles out on the market, but are the only ones I had access to.  In an ideal world, I would have liked to include the KJW/Tanio Koba M4 GBBR, the Inokatsu M4 GBBR & maybe the Bomber M4 GBBR as well. Maybe someday.  But for now, these three rifles will have to do.

 So let's cut the crap, shall we?  

There I was, testing out the potentially marvelous new Elite Force .32 MilSim Max Bio BB when I started running into a little hiccup with my testing platform.  I didn't get to fire too many rounds of the newest release from Elite Force's exceptional line of BBs, but from what I saw initially, I've definitely got my hopes up.  Flight path looked pretty good.  I was using a G&P WOC, Western Arms-based Gas Blowback Rifle (GBBR) and began having some trouble with the trigger getting stuck while firing in semi-auto. 
Additionally, the selector switch was getting stuck in full auto when I would switch to that firing mode.  It then became impossible to switch out of full auto by hand unless I popped out the lower receiver's body pin and opened up the gun.  This put a temporary halt to my test of these BBs until I could resolve the issue.  However, I hadn't really had any experience taking these rifles apart before (always had my buddy do the tech work in the past), so I had to blaze a few new trails.  I don't usually like to blaze new trails these days because I usually don't have the time.  But luckily, I was dealing with a Western-Arms-based Gas-Blowback Rifle, so the internal design is relatively simple in nature.  A definite plus.
