Question: How Hevesy is it
Document: this is the best gun i have ever used. it is very cheap and definitely worth the price. the scope and bipod are amazing and the gun is very fast and accurate. it shipped in about 4 days. i am very pleased with this gun.
this is a very good looking and great functioning airsoft rifle. i just received it today, and put it together in about 5 minutes. it shot very accurate before i zeroed the scope. i recommend .20 gram or .25 gram bb's, anything heavier makes it to weak. it shoots about 420 fps with the .20 gram bb's.
this gun is very accurate and is more than i expected it to be. it has a very good bolt, not to stiff and not too easy to pull back. the weight on it is not front heavy and not back heavy either but it is hefty. it shoots at about 400 fps with .20 gram bbs (which i recommend). the bolt, barrel, bipod, and trigger are all metal but the body is made of a very durable plastic.
one is behind the trigger guard, and the other two are before and after the area the clip goes in. overall this gun is great.
it is a sturdy all out awesome gun and its really not that hard to assemble that's why I was surprised it was so sturdy
i was at first concerned with the gun because of the low price and i had never heard of it before, but when i compared it with my friends WELL L96 we both agreed mine was better. over all this is truly one of the best airsoft guns i have ever seen and i recommend it to beginners and mainly mid entry airsoft players.
Well, first of all im using my moms acount. 2nd of all i love this gone it takeslike 3 min to put togther its is awesome to play in the snow i was lighting up my brothers.
