QB78步枪入门？

longlive

二氧化碳一般要看满瓶的时候多少枪打空，然后记得要保留大概5-10枪的余量，比如说我的Crosman Vigilante 60发打空一个12克气瓶，最后10枪基本就气压不稳定了，速度下降很多。

打靶的话平头弹.177口径在10米以下都很稳定，我估计600fps 20-30米大概都可以。那些稍远些的估计要.22 或者 .25口径的啦。

其实二氧化碳的最大好处就是省劲，不费力。

看上去还得时刻记着自己发射了多少发，有点头疼。

不知道如果买工字压杆的话（好像叫什么B3 air rifle? ...

关键看你干什么，如果只是打靶打精度，因为你不考虑PCP，那其实单次压气最好，Daisy 753现在在亚马逊还有卖的，非常好。要不就选个多次压气，Crosman 2100不错。 弹簧枪打靶大多数威力太大，以前弹簧枪打靶中IZH 61 是神枪，也不会夹手。现在Air Venturi TR5好像是仿IZH61 的，但是质量怎样就不知道了。

PCP就算了吧，我问了下本地运动用品店，一个9 oz二氧化碳钢瓶充气就2块钱，按打一百发算的话每发2美分， ...

太低估9OZ的容量了。下面有这样的说法：

We’re often asked “How many shots can I get from one CO2 tank with a QB79?”

OK, so here’s the scoop...

The QB79 can be used with 3.5-ounce and 9-ounce re-fillable paintball tanks. Or a Daisy Avanti re-fillable tank. These are all mounted directly onto the gun. Alternatively it can be used with Crosman AirSource 88g tanks, in this case a Crosman AirSource/Paintball Adapter is required.

Our photograph compares a 9-ounce paintball tank to the Avanti tank, an AirSource tank with adapter and 12g Powerlets, as used on the QB78 model.

The number of “good” shots per tank are:

2.5-ounce Daisy Avanti tank  about 150  re-fillable
88g AirSource tank (adapter required) about 220 single use
3.5-ounce paintball tank   about 240 re-fillable
9-ounce paintball tank   about 630 re-fillable

By comparison, a QB78 with two 12g Powerlets provides about 50 “good” shots before the point of impact starts to fall significantly.

As with many other things in life, “your mileage may vary”. But these figures are a good approximation.
