D-boys BI-3881 M4 RIS SD

this is my first review EVER so please take it easy on me. kk here goes....


i bought the D-boys BI-3881 M4 RIS SD from master blasters not too long ago. it has been a very good gun. i have never upgraded it or ever had the need to repair it. i have shot around 10,000 rounds with it. it shoots straight and true. it shoots around 380 fps stock which is great. the gun cost me about $175. it is pretty much all metal with the exception of the stock.(ABS plastic) it is very durable. it takes an 8.4v nunchuck battery. it has 7mm metal bearings. the hop-up works very nicely. this gun has exactly 5 RIS rails. i have a red/green dot scope mounted on it now. the only problem i know about it is the battery rattles a lot inside the stock. this can get rather annoying, but does not really affect the performance so it does not matter much. overall, i recommend this gun soundly. as far as i'm concerned if you want a gun that you really won't have to do any internal work or repairs(duh) then this is a very good choice.

to solve that battery ratling just put some tissues in with the battery to keep it in place

thanks.

Tissue is a good idea and on the right track but if you can find foam rubber or use electricall tape to pad the battery i would feel more comfortable reccommending it.

Agree, something that is not so flamable in an area that does generate heat especially during charging, if like me you charge the battery in the stock.

ok thanks. i'll look for some.
