I purchased this GB about 3 Months ago and installed it on a Frankenstein TSD/SRC M16a2 with a King Arms Hop-up, Matrix TBB, and 11.1v/4000mah lipo. My first mistake was to use a hard bucking (4-5 bb's would shoot/roll out at a time). Contrary to what many say on here, a soft bucking is best for this GB. The construction is very sturdy and it seems to handle my lipo well. I've used it in the field maybe 10 or so times and it performs well, although it shoots a little wild even with .25's. I'm installing a better quality bucking with a concave spacer in an attempt to fix this. I didn't know how powerful it was until I got it chrono'ed at an op last weekend: consistent 435 fps with .28's! The fps limit was 420, but luckily my friend was working the chrono booth and let it slide.

-Great quality for the price
-Sturdy/well built

-A little noisy
-May be too "hot" for some ops.
-Shoots a little wild (probably not the GB's fault though)
