Here are some pics of gear I've owned in the past:
Beretta Cougar "F" M8045
H&K G3
M4A1 with M16 buttstock
MP5-SD6
The M4 was my first airsoft gun! I had good times playing with it but I wanted something in the more of a sharpshooter role so I sold it to buy the G3. Sadly the guy who owned the G3 ripped me off and disappeared with my money. The G3 had a mechbox that was snapped in half and repaired with JB Weld. Well it finally resnapped and then I found out I owed $400 in taxes. I sold the remains of the G3 for $250.
A year later I saved up my money and purchased the MP5-SD6 to get back into the sport. Found the M14 for sale for a decent price and picked it up to get back into the sharp shooter role. Realized I spent a little too much and sold the MP5 to help cover the dent in my bank account.
The cougar was purchased between the M4 and G3 but I sold it due to there being a shortage of Cougar parts and I was nervous about it trying to repair it.
