Things I liked: Price, Thick Padding, Carry handle, Shoulder strap, 5 Mag pouches, label window so I know whats inside (I have various guns), enough room inside for me to also include a sling & 5 extra 30rnd P-Mags - that's 10 mags (300 rounds, about $90, 11.2lb's worth of just ammo!) total I can carry in one package.
Things I would have changed: Only thing I can see is possibly going with YKK's heavy duty zippers, I have not had a problem with the ones used yet though. It's a great value as is.
What others should know: I use these for my real AR's! It fits my BCM Standard 16" Mid Length (LIGHT WEIGHT) Upper Receiver Group w/ Daniel Defense OmegaX 9 Handguard, fitted with a "High" Riser & Vortex SPARC, Ergo RH Grip, with or w/out a Clubfoot IMod collapsed - with plenty of room.
Things I liked: Surprisingly accurate (for how inexpensive it is), large ammo capacity, great price, more than enough power for backyard plinking etc. at 10 pumps (nornally just use 3 for knocking cans over)!, kit come with everything you need to get started, Awesome green fiber front sight that I didn't even know it came with - GREAT for old eyes!
Things I would have changed: My 6 year old boy found it to difficult for him to pump (why I bought it...), it's even a workout for "mom" haha! I told them to eat their "Wheaties" as I didn't have any issues cocking it though!
What others should know: Unless you have a 6 year old with ape arms, this guns length of pull is to much for them!
