Question: how long from butt to bore is it?
Document: great gun but i'd recomend something more practical, prehaps a hand gun some thing you can shoot in your front yard without worring ppl dring by.
This is also good for collectors or just backyard target shooting.
My son loves this gun...It is very powerful and will break the skin if hit with it. It is large and heavier than his other airsoft and bb guns.
Must use high quality .25gram bbs or heaver ( excuxe the misspell)other wise you will feel like crying because u bought a 90 dollar gun. BTW you must buy a scope and scope rings... i recomend utg scope rings if your getting a 1 inch scope. If you have no idea what i am talking about DO NOT GET THIS GUN!
Good gun for backyard and midsized wars.FPS: 280-350 (.2g bbs)Effective Range: 50-80ft.Pros:' Quiet gun - enemy will barely hear the shot from about 80ft. away (During summer with cicadas and birds and lawnmowers, the enemy will NOT hear the shot from 80 ft. away).' Not to powerful, not too weak' 2 mags - can easily purchase more: Type in MP001 MAGAZINE into amazon.com.
(I bought one and it works perfectly)' No cons' Easy-to-reach hop upUSE .2g BBs!! !,  No heavier than .25, no lighter than .2. .12s actually wont damage the gun (the guns power isn't all that) but they are extremely inaccurate. .23g WORKS FINE TOO!! !ALL IN ALL: This is a good gun for beginners who have backyard wars.
Answer: no
