Can the pro's here outline the intricacies of driving a gas gun? Are there aspects that are polar opposite to the bolt gun? Is precision fire attainable with the smaller collapsible stocks?
 
Re: Driving the gas gun

i think what bolt is saying, or at least hinting at is try the search funtion. but to answer your question to the best of my knowlege, no there are no oppisites to driving a gas gun, as the basics are the same (sight picture, trigger squeeze, and breathing, being the key factors) gas guns tend to be inherintly less accurate than bolt guns because there are more moving parts, each with it's own tolerance for slop, but thats not to say you can't get a good precision rig that thats a gas gun, look at the KAC M110, and and the rifles leading up to it, or hell a panther, or Armalite with a custom barrel and a match trigger is pretty accurate. i don't know your expeiriences, or how well you drive a bolt gun, but if you can drive one really well you should be able to drive the other just as well. there are people here who are way more expeirienced on this site than me and Boltripper is one of them, though he tends to scare the new guys off with his antics, try the search funtion your topic has been talked about at least a hundred times, if you still can't find it keep watching this tread and someone is bound to tell you better than i could
 
Re: Driving the gas gun

Running a gas gun AKA, AR-10 style, is the same fundamentals of marksmanship as any other rifle. The main answer to your question is follow through until the rifle stops in recoil.

If you have any part of the fundamentals of marksmanship jacked up, you will have a jacked up shot grouping.

So if you have a AR-10 style rifle, and you can not get it to group, you need to go get some training.

I'll try some deeper searches. Thanks. Bolt doesn't scare me, he's just a crazy old man

Re: Driving the gas gun

I had a sass once and was able to get 1-1.5 moa out of it. Would it shoot better with a diff shooter? Maybe. There is just all this talk about auto's being different and I would agree but would like to know others experiences.
 
Re: Driving the gas gun

For me the fun factor is higher with a gas gun,I waste more ammo but hell thats why I reload.I don't no if I just got burned out on my bolt guns but if I had to walk up to the two and grab one to go shoot for the day it would be a gasser.
 
Re: Driving the gas gun

OK, I'm no 'pro', but I'll answer the questions you asked: I have found gas guns to have three distinct recoils. With the bigger caliber AR's you will be able to feel the third phase as the bolt slams forward and pulls the rifle off your shoulder. If you disagree, or can't feel it, try shooting the same AR single shot with a Bob-sled that locks the bolt open after the shot. I hold the trigger back, extend the follow-through, and don't reset the trigger until after the rifle settles. And Yes.
 
Re: Driving the gas gun

Or get an adjustable gas block and crank off the gas and manually cycle the bolt. I used an AR10T for FTR comps that held with the front of the pack using this method. It also keeps the works cooler and cleaner.

Re: Driving the gas gun

There are some differences in the two, and the first is accepting that they are obviously not as accurate. However, both my SR 25 and its replacement really settled down after the first couple hundred rounds and outshot many a boltgun, or lets say, the owners of those rifles...
To answer your question, I would say there is a distinct difference in recoil and the extended follow up answer is something I have been doing without ever realizing it. The other is that a gas gun rarely has a grip that places your hand/trigger finger in the correct position for an "anatomically" correct or efficient trigger pull. Meaning its so close to the trigger shooters tend to wrap their finger around the trigger. I have found that building up the back of the grip with hockey tape and foam helps pull my hand back and place my finger more properly on the trigger.
Plenty of shooters seem to let the semi auto thing get the best of them, and they use volume of fire to make up for taking precise shots, take your time, treat it as the most accurate weapon in the world, and you just might be surprised.
 
Re: Driving the gas gun

I think Graham nailed it.
A premium AR-10 will easily shoot sub moa.
The first part of the fundamentals are the same. The trigger pull may be compromised a bit based on the grip as mentioned above. But what I am finding with my new toy is the trigger pull and follow through are key. Slapping the trigger like a pimp slappin his bitch will put you all over the place. Riding the recoil through the entire cycle helps to get the bullet downrange without inducing so much shooter error.
As far as the bolt sliding into battery and pulling away from the shoulder, I feel it. More like it takes away some of the pressure for a brief moment.
I am waiting for an adjustable gas block. I built mine in 6.5X47 Lapua and want to tune the load and the gas to minimize tearing up the brass and recoil.
