After all the fun I had repairing his m4a1, I had to buy myself and my daughter an airsoft rifle also - Kwa's of course. My daughters G36c arrived about 40 days or so ago (waiting on Airsoft GI to mail original invoice). My m16br arrived about 10 days ago (saved invoice ). Today I received my new F1 Chrony, yeah I jump head first into all hobbies, according to my wife anyways! I'm embarrassed to mention everything else on it's way. I think my son may have tricked me into this hobby, lol.
Eager to test the F1 Chrony I ran our 3 Kwa rifles through it. I used .25g bb's in all of the tests. My son's old v1 m4a1 averaged 386 fps. Which like I mentioned has run approximately 80,000+ rounds through it, completely original minus the trigger post mod and my re-lubing of the gearbox/cylinder. My two week old m16br only averaged 360 fps. This was slightly disappointing since it has a 130 spring instead of the 120, and is a lot newer. My daughters 40-50 day old G36c, was even more disappointing. It only averaged a measly 248 fps.
This really surprised me since she rarely uses her rifle (less than 2,000 rounds). I plan on calling Airsoft GI this afternoon to see if I have passed the warranty by a few days or not. If her G36c is still within the 45days I plan on sending it in, even though I can't wait to break open a v3 gearbox!
My main questions are:
If it is not within the 45 days, what would be the most likely reason for the fps drop? Also, is it normal for my m16br with a 130 spring to be shooting lower than an 80,000+ round v1 m4a1 with original o-rings? I can't imagine my re-lubing of an old m4a1 would have superior compression compared to a new M16br.
OT: The m4a1 looked in almost perfect condition after 80,000+ rounds minus the trigger post!
