Lazi - regarding your list of rifles and thoughts...

M1A = increased firepower and ammo compatibility with the GSR. This could fill in for the AK you mentioned.

AK = Redundant item? The M1A and GSR can do everything an AK can except high-volume CQB type work. However, if you want "high capacity CQB" ability then an AK is hard to beat. The more I shoot my AK's the more I prefer them to my AR's. I do have concerns about the availability of 7.62x39mm ammo after combloc imports stop. Therefore consider a 5.56x45mm variant.

Pistol Caliber Carbine Notes:

1) I typically do not endorse pistol caliber carbines, because you can have full power rifle cartridges in the same size package.
2) I only endorse pistol caliber carbines when a "companion handgun" is involved.

Marlin 94 (357Mag) = If you have a 357Mag handgun this could be the companion carbine I would select. Overall, however, this rifle would be bested by the GSR (similar size with greater accuracy, reliability/durability, power, and firepower) and/or AK (greater reliability, power, and firepower).

KelTec Sub2k Notes:

1) Again, I don't like pistol caliber carbines, but understand the companion role.
2) The KelTec is handy because it folds in half and can be stuck in a backpack thereby fulfilling a "discrete purpose". However, folding stock AK's are just barely larger and more reliable, powerful, and have higher magazine capacity.

KelTec Sub2000 (40SW) = If you have a Glock 22 or 23 this is the companion carbine for it.

KelTec Sub2000 (9mm) = If you have a Glock 17 or 19 this is the companion carbine for it.

Ruger 10/22 = Must have. A quality 22LR rifle is a mandatory item, and the Ruger is as good of a choice as there is. I have a couple, and my wife's Bug-Out Gun is a 10/22.

Regarding the GSR's accuracy:

I've read 50+ pages of internet reporting on the rifle's accuracy. Excluding one poster (who took off the flash suppressor and monkeyed with the barrel) everyone is getting 1" or better at 100 yards. Obviously the quality of ammunition and iron vs scout vs traditional scope makes a difference here, but several handloaders are getting MUCH better than 1". In my opinion, the 1MOA issue is overrated and doesn't take "field condition shooting" into account. Just because a 15 pound bench rest gun will shoot 1/2MOA doesn't mean that its worth a crap for those of us that actually FIELD our weapons. The GSR's light weight, good balance, and short length combined with the 1MOA (off a bench) ability means that you'll have a 7 pound (or 7.5 pound with a Leupold 2.5x Scout Scope) 7.62x51mm (308Win) rifle capable of dropping a man dead in his tracks at 300+ yards from a decent field position. I cannot ask for more from a "survivalist inspired" firearm.

Accuracy Side Notes: From what I've read...

1) Since the GSR has a fairly heavy barrel (it steps down in front of the scout mount, but is still "medium weight" all the way out to the muzzle) - the rifle doesn't start "stringing" shots when the barrel heats up. Since a prudent survivalist isn't going to be running through 30 round strings this might not be an issue. However, preparedness is about covering all of the bases so knowing the rifle will stay on POA after being "used heavily" is a good thing.

2) The GSR barrel rifling is 1 in 10" which means it will favor heavier bullets (1/11 favors 150gr or lighter).

Hunting Side Notes:

1) 308Win is capable of killing anything I'd care to hunt especially considering the 1/10 twist means I can use 180gr bullets.
2) The data I've read shows the little 16.5" barrel yielding 2500fps with 168gr bullets. This is good ballistic performance.
3) 1MOA with the right ammo. Means 300yd ability. I question the ethics of hunting beyond 400yds anyway.
4) Light and short = easier to hump around all day.
5) Quality back up sights, two scope mounting options (it comes with traditional rings and the scout mount).
6) Durable stock.

What's not to like? Its an ideal hunting rifle IMHO!
