looking for some advice/ tips on how to stablize the gas gun and any advise on getting better groups...

I have two rifles from gap. the bolt gun is a dream. It will be in my collection for life. sub moa 5 shot groups are no issue whatsoever with my handloads

Thanksgiving of last year i received an armalite gas gun from GAP once again.

PRS stock, with a swiveling bipod. the only thing i have added is a bubble level, nightforce scope (GAP installed) the only thing i have done is moved it forward on the rail as i was not getting enough eye relief, and monopod

I bought the podloc to help stabilize the rifle.

i swapped the non swivel bipod on the bolt gun to the ar10. I still can't get the rifle to stop flexing left and right. I have tried to use the monopod and without by using several different rear bags. I just can't get comfortable... groups = the suckage. im talking rarely under an inch group. xm118lr from this last weekend was 1.5 inches

I've tried 155palma VV n140 accuray load.
xm118lr
blackhills 168
blackhills 175
hornady amp 178grain with 43.8 grains of Varget at 2.810 which lock up the bolt.... thats fun the clear. im going to seat the bullet lower and try again soon
thats about it for ammowise.

after shooting the mcma5 then getting prone on the gas gun. I just feel to cramped is the best way i can describe it. I am going to start another thread on how to properly utilize the LOP on the PRS stock..

thank you for any advice

I'm assuming you are familiar with the fundamentals of marksmanship. With this being said I have found (with my rather limited ammount of time behind a gas gun) that your "follow through" is extremely important in achieving good accuracy. Practice... Practice... Practice... Consistancy = Accuracy. Hope this helps.
 
Re: can't get used to shooting the ar10 platform

KAC makes a swivel that screws right into their rail. That gets the bipod as low as possible.

Do you have a match trigger in the AR10? 1.5MOA seems a little larger than potential. If you were at 1MOA or under, that would sound more right.

One of the things to remember also is the semi-auto is capable of hitting multiple targets with speed not capable with the bolt gun. For what little you lose, you gain a lot.

Some guys never like auto-loaders, and want to trade them back for bolt guns, and if that's you it's definitely a preference thing.

About the only really important fundamental I could think of is straight line body position behind the gun. If you're using a sandsock and have a grip that drops your hand slightly to allow you to pull the trigger to the rear in a straight line, that's about all there is to do.

An improved grip like a MIAD or Sierra Precision SPR grip (if compatible with the AR10) would help with that trigger straight to the rear anatomical thing.

<span style="font-weight: bold">Another thing to check is the concentricity of the thread if you have a muzzle device on it. If the thread is out that can cause the rifle to throw fliers.</span>
 
Re: can't get used to shooting the ar10 platform

if the rifle is flexing left and right, you need to get your body positioned better behind the gun. when you gun is moving around like that it is because you are forcing your shooting position instead of being in a natural position. make sure that your stock is set to the proper length for you. If your GAP-10 is any thing like my GAP-10 the gun should be able to do a lot better than MOA.
 
Re: can't get used to shooting the ar10 platform

For a rifle that wants to rotate, I'd also look at the cheedweld/cheek pressure and the trigger hand contact.

Comb too low and you have to "climb" it or "jaw weld"? That can work if you are super-consistent, but neck fatigue sets in.

Comb just right? Then are you resting the head naturally or forcing it in any direction. This can be easy to drift away from while trying to load the bipod and keep consistent buttplate pressure.

Trigger hand--enough grip to offset trigger pull, or is the grip a tool to force the rifle into position? Pressure between that elbow and the palm, or a neutral grip?

With all this, it's consistency. If a trigger forearm/elbow is jamming the palm into the rifle's grip, recoil dynamics could throw that shot .5 to .75 MOA up and to the side away from the elbow. But if that's what you do *every* time and your elbow is "stuck" to the ground the same way every time, you would just zero to it.

Without turning into a boneless chicken flopped on the ground, relax and let the rifle do the work.

Start with Basic Marksmanship
Stock to cheek weld, varing amounts of pressure will drive the rifle off target
Butt to shoulder placement, you need to find the same pocket every time
Grip, same grip every time
Non firing hand placement
Elbow placement
Follow through on trigger after shot breaks. DO NOT slap the trigger.
Be honest with yourself during practice in the house, and see if you are failing at any of the proceeding.

Might get a buddy to take a video or a pic of you in your shooting position right before and after your shot to see where you are. I reccomend being sqaured up right behind the rifle...trigger squeeze makes all the difference in the world.
 
Re: can't get used to shooting the ar10 platform

Have you tried it with only sand bags or a mechanical rest?

For some reason, I just can't get good groups out of a bipod. Heck my ruck or range bag does better for me.
