Question: Are they biodegradable? That's must!
Document: Crosman is THE BEST brand. they never jam. work great. look good. and for a very cheap price. a must buy.
My grandson was very pleased with this large container of airsoft BBs. He is very into airsoft guns and playing out in the fields with other boys. He is 14. Not recommended for younger children though. Must wear goggles to use.
It's .20g, but I would prefer .12 but it is actually pretty good, very accurate and is obviously biodegradable. No complaints.
Great product, great price, fun non lethal sport.only gripe is that they are not biodegradable so they do stay in the yard if used outdoors. I will use in a trap.
I was looking for .20g airsoft BBs and found these. The price is good and the quality is great. These are the ones you should order.Pros:-Inexpensive-Good quality-Bottle comes with carrying handleCons:-Not biodegradable
These work great in my son's airsoft gun. Easy to find and pickup as they're white. The lighter weight ones don't go as far and the biodegradable ones just leave junk all over the yard that takes a short forever to degrade and then pushes chemicals into the ground.
Haven't tried the BBs yet, so disappointed with the care and packaging of the product. Bottle must have come open and been repacked by UPS. It is apparent that about half of the BBs must have been lost in shipping. Bottle should have been sealed before shipping and fulfillment center should have packed better. Wanted a bottle rather than a plastic bag for storage purposes and paid more for the convenience of the bottle, but lost half of product. Very disappointed.
this bottle of BBs worked fine in my airsoft gun and the were semi fairly priced. they didnt damage my gun in any way
these work great in my high powered airsoft pistols and rifle. I am glad i bought a high capacity like this bucket full. I've had no problems with these, and would recommend this product to anyone.
these things ruined my $150 dollar AEG. USE THESE BBS FOR CRAPPY GUNS OR SPRING GUNS ONLY UNLESS YOU WANT TO DESTROY THE INTERNALS OF YOUR GUN
Answer: yes
