Gas Sniper Rifles?
Lately, I've been looking with great curiosity at some bolt action rifles and I had noticed in the classifieds there were a few gas bolt action rifles.
Now, I've only looked briefly on youtube at the performance of a gas sniper rifle, but is there/are there any particular benefits to having a gas-based sniper platform? I would assume that perhaps it shoots harder than its springer counterpart (if it has one) but does the user feel any sort of blowback or recoil? If so, it doesn't really look like it.
And while we're at it, what particular downsides are there to having a gas-based sniper rifle apart from having a spring sniper rifle aside from having to refill the gas every so often?
Thanks in advance for the input guys.
