I shoot 50-100 rounds through my M305 everytime I go to the range. Im about 400 rounds through the gun so far.

The 6-10 first rounds are very accurate (about 1 1/2'' groups @ 100), with aguila 150 gr. and with XM80C.

That is for the first 10 rounds. After those first rounds the group open up and 30 rounds through I am at 6''. My understanding of this is heat affects the gun a lot, especially the stock, wich becomes really soft when the gun gets hot. Am I on the right track on this one? Will changing the stock help with this, and if so, what are the affordable options for a stock that can take some heat?

Also I need a cheek riser so I can repetably look through the scope from the same angle. Does anybody here has any input on the best options for a cheek riser, be it an add-on integral in a good stock?

Thank you guys for the help!
 
A little more information is needed. If you have multiple mags loaded up and are not letting the barrel cool in between mags it may just be the barrel is heather and groups are opening up. If I'm shooting my LRB Or previously my Springfield national Match that are medium barrel for groups I'm allowing 40?seconds to a minute between shots to ensure I don't over heat the barrel. The barrel heating up and opening up groups is going to happen long before you heat the stock up enough for it to have a poor fit

Are you using the original chinese black plastic stock? If so, that is at least half your problem. These stocks are too long and the front ferrule puts pressure on the gas system, causing vertical stringing after a few shots. These stocks ALWAYS need to be either repaired or replaced to get optimal accuracy out of the gun.

Also, how much time are you allowing between shots? The GI profile barrels heat up quickly and stay hot, they are NOT match barrels.

Yep chinese black stock and stock barrel. When the gun gets hot it gets loose at the front ferrule/gas system junction. My POI shifts downward as well, so this is what had me suspecting the stock. Im not letting the barrel cool a lot to be honest... Its part of the fun to shoot fast!

The gun still shoots very accurately fo a semi! I just wish it would stay that way a little longer... As I need a cheek riser and a spacer for a longer stock anyway, are there solid options to correct all these problems at the same time? Im not looking for anything ''tactical'' looking, as part of why I like this gun so much is because it looks very much like any old hunting rifle.
 
I have seen a sheet of KYDEX plastic heated and formed over the comb used as a cheekrest. There are slots in the riser and two bolts with thumbwheels hold it in place after adjustment. The design needs two holes drilled through the stock, but these are not necessarily rifles that need to be beauty contest challengers - more tractor pull participants. I can't remember who on CGN makes and sells them .... anyone? Bueller?

Nice try, but those Kydex cheek rests are only useful if you want good eye alignment with the scope, combined with consistent cheek weld and easy height adjustment.

If you want a comfortable cheek rest in the event that you fall asleep on your rifle, the foam cheek rests are much better.
 
I gave up with the original stocks, wobbly when warmed!

I would recommend a chassis or a wood / laminated stock. My favourite for the money is the M14.ca Blackfeather.

On the wooden stock, a Bradley Cheek piece is hard to beat. A bit pricey, but well worth it.

Not adjustable , they come in 3 sizes , maybe 4 , I don't recall offhand , you can judge the size you need from rolling up a towel to about the thickness that feels right and taking a measure on that .
And being foam they're more comfortable and forgiving , you can crush your cheek down into them and not be uncomfortable , unlike kydex .

Looks good, Is it adjustable for height though? il looks like a solid piece of foam you can't adjust?

Easy to beat at half the price with a Canadian made product, unless you believe the Bradley shills who claim that better materials, better design, easy adjustment and the gold standard in precision forming of the Canadian product is highly over rated.

That blackfeather stock is pretty much the price of the rifle... Where can wood stocks be found?

Boyd's.

The chassis stocks have their place. the Blackfeather is the lightest among them, but still heavier than, say, a USGI fibreglass stock. The USGI fibreglass stocks will shoot batter than 95% of the people using the rifles if in spec and the rest of the rifle is set up well. In fact, Smith Enterprise recommends stock USGI fibreglass for their Crazy Horse rifles they build for the military.

In the military, the chassis rifles are for DMR shooters firing from fixed positions. Not a bad thing, but you need to decide what role you want to employ the rifle in. chassis systems would have to be carried all day if you are looking for something you'd taking on walks.

If you are a range shooter only, sure, get a chassis or a NM style oversized wood stock and bed it.

Which product are you referring to? I have had a go of several brands and Bradley I would rate as the best I have owned so far.

I am not sure on the aspect of material / construction etc, but the two I have get a lot of use and switched out on several rifles. They work, are easy to switch around and hold fast to whatever stock they are applied to. The one I have on a Norinco m305 is over 7 years old and has been subject to 9,000+ rounds and is as good as the day it was purchased.

I like to the idea of a Canadian manufacturer, but was not aware there was one. I would like to see if they hold up as well as a Bradley, none of the others have.
