1) Manufacturer, Model Name (name of weapon on box, and weapon replicated if different from model name)
- CYMA, FAMAS [F1]

2) Date Obtained
- 11-21-11

3) Initial Cost
- $170

4) New or Used
- Brand-out-of-the-box-still-shiny new

5) Mechanical Problems (Gearbox issues, hopup issues.. basically functional performance related -- supply date of issue)
- Gearbox Lockdown-11-26-11
- Hop-up problems - Fixed as of January 2012. Discovered Hop Over-sensitivity and tendency to 'overheat' and be inconsistent, consistently.
- Catastrophic Failure: Mid-2012. Piston head separated from piston assembly, scratching cylinder, piston, and destroying cylinder head. Separate wear detected on some other parts of drivetrain assembly. All damaged parts ordered January 2013, Gearbox rebuilt April 2013. Cause of damage was traced to metal spacers placed to correct AOE; screw was not loctited, and came undone during moderate firing runs.

6) Esthetic Problems (Paint damage, cracks in body, loose parts.. physical construction related -- supply date of issue)
- Sticky cocking handle - Fixed 1-26-12 by sanding down some protruding body nubs.
- Cracking on inner body, caused by over-tightened screws. Fixed upon discovery with cyanoacrylate.
- Barrel attachment flanges snapped off after rifle barrel accidentally impacted wooden wall during transition from low ready to firing state.
- Wire routing flange snapped during above incident

7) Rounds fired between failures (think how many bags of BB's used before it failed. If no failure, list rounds fired up to this point)
- 300 rds. to gearbox lock, 1500-2000 rds. to date.
- Further 1000-3000 rds. before piston head snapped off and destroyed internals in April 2012. Pending parts as of May 2012.
- Roughly 7-10 000 rounds fired to date, as of June 2013.
- Roughly 10 000 rounds as of selling date

8) Changes to Internals and Externals (upgrades, mods, dates)
- Fixed sticky cocking handle.
- Relubed/greased.
- Aftermarket parts pending - Update, no longer pending.
- AoE corrected.
- Scope mount MacGuyvered, Bushnell 2-6x28EE or AimPoint CompM4 mounted
- M/B Piston added. Lonex Piston Head added. New T7 Cylinder added. New V7 Sorbo Buddies Sorbo Pad added. New Lonex M90SP Spring added.
- Front Leaf Sight removed. Blade sight kept in place.
- Body painted.
- 9.6V Battery equipped.

9) Resale Date and Value if applicable.
- Traded in October 2013, exact date currently unavailable. Approximate Package Value (two batteries, rifle, three magazines) $250.

10)Notes and Comments (Optional)
- It seems quality control is non-existent, and many of the self-tapping screws are screwed in so hard the body is cracking. An 8.4v is too slow for the gun; a 9.6v is recommended.
- Update: 9.6V added. Trigger response is crisper, ROF estimated at 12-15 BPS.
