I run the KWA LM4 PTR Gas blowback rifle, with a KWA Mk2 1911A1 PTP as my sidearm. I absolutely love the guns. The M4's weight is... maybe 1/2 a pound lighter than the real M4 we have sitting in the gun case downstairs. Kick is almost equal, real steel sights, comes apart and is maintained in almost exactly the same way as a real M4. (Use a 100% silicone oil lubricant otherwise you can destroy the gaskets and seals and then BBs no fly.)
KWA LM4 Pros:
-Extremely realistic.
-Easy maintenance.
-No freaking batteries.
-Good out of the box accuracy.
-310 FPS with .25's in cold weather, 350 in hot. Perfect FPS for Texas Field Limits.
Cons:
-Green gas is expensive. If anyone knows a good pouch to put on a molle rig that can hold a full size propane bottle securely please let me know.
-Magazines run $40-$60 a magazine when they actually have them in stock.
-Fragile hop-up adjustment, be careful! While not during hop-up adjustment I did get a bad BB, that the bolt smashed up and snapped off one of the teeth that adjust the hop-up. Not super damaging but you want to be very gentle with your hop-up tool. (Out of 20,000 BBs fired that's actually a pleasant surprise for me)
-O-rings at the Fill valve drop out on me. But I have this problem with all KWA magazines. Replacement 0-rings from any airsoft retailer are a crime to purchase. (Like 10,000% markup on the damn things) Hit up
McMaster-Carr if you need 'em, you want the Buna-N O-Rings 9452K112 rings. 100 O-rings for less than $10 including shipping. Little tricky to get on, but I have yet to have one of these drop out on me in the field and I end up crawling around just about everywhere in a match.
The 1911A1 comes apart exactly like my real 1911A1, my only complaint is the plastic outer barrel and aluminum slide. I need to see about getting a steel barrel and slide for it so that it actually weighs and feels like my real 1911.
Pros:
-Has a good 30 yard range for a BB pistol.
-Accurate
-Extremely realistic
Same Cons as the M4.
As a backup I use a Classic Army LWRC M6, shorty M4. Nice weight, decent gun now that I actually have it fixed. The air nozzle had a bad day when I went to chrono a couple weeks ago before getting the KWA. Decent rifle for the price, I'm planning on dropping a weaker spring into it so that it's CQB legal. (270 FPS with .25's in Texas to count as a CQB gun. You don't need a whole lot of speed for someone 20 feet away.)
For the future I want to put in a tightbore barrel for the KWA M4, and get a WE M-14 GBB and set it up as a DMR platform with a decent scope on it.
Don't have any pictures of the gun all by itself but I do have a picture of me out at Texas Paintball the other week. I'm the guy on the right with 3 different types of camo.
