Product description
BI-3981M airsoft rifle
The BI-3981M replica is made of metal and polymer. The SF-type buttstock, pistol grip and RIS rail facings were made of polymer. On the other hand, elements such as the replica's body, external barrel, dummy gas tube, RIS rail system, adjustable reloading lever, hop-up chamber, tactical sling eyelet, magazine and stock guide are made of metal. The carbine has an adjustable hop-up system, which can be accessed by pulling back the reloading lever, which opens the flap of the shell ejector concealing the adjustment knob.
The kit does not include a battery and charger.
The kit includes:
- replica
- magazine
Battery included NiCd
rechargeable battery is characterized by high efficiency
current-carrying capacity, but there are disruptive effect on memory.
Should be unloaded and loaded in the full cycle, ie, it is recommended
to fully discharge, and after unloading must charge the battery
immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the
life - on the other hand, they earn about 30% more capacity. | No |
Blow BackBlow back is a simulation system of the cocking lever - it imitates the
work of it as the equivalent sharp. This system raises the realism and
adds a lot more experience during shooting. | No |

family have gearbox v3. | Gearbox v2 |
Hop-UpHop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy). | Yes |

2016-10-11Well then, itself I really like the gun. But it is realistic to paint the reality of it so a couple of things to remember about him. First, as the biggest problem, though not serious, that RIS little cluke. The RIS upper part can be fixed with the screw fore the first sighting. The under of the RIS still clucke. This metal plate on the inside edge of the fold of RIS can be drawn closer and then it no longer cluckes. The gear box bearings are replaced with better quality. I have buy a weak spring, which around 380 FPS shoot because the original spring produces around 410 FPS, which does not comply with the rules of the game in Hungary. The factory magasin little clucke. The rifle is full metal , except for the grip and stock, but they are made of high-quality sophisticated and beautiful plastic. The dispersion I have not looked, but not great based on current shots. So it's not perfect, but the price-performance ratio is very good, especially devaluation.

2014-03-15Nice gun for this price! although it shoots 400+fps with 0.2 bb's keep that in mind because i have to change to spring to get under 360 fps.

2014-03-06Bought this with a lot on anticipation, and expected it to preform just as an airsoft gun should. However, after it arrived and I opened the package, I have found it to be money well wasted. The gun's upper receiver does not even line up properly with the lower receiver meaning that there is a big gap between the receivers. Also, the sound when firing the gun is absolutely horrible, like a "twang" sound. Disappointingly, the guns accuracy is terrible as bb's fly all over the place even when the hop up has been adjusted. All in all, this gun has been a major disappointment, and I expect that gun-fire.pl will get back to me about my problems with this product as I have spent a lot of time and money on buying from them. Please make a valued customer feel more welcome again as I am not impressed.
