Its an Armalite. Only reason it wont shoot accurately is because you are not a good shot.

I have read nothing but great things about the 10Ts. I have a regular A4 and it shoots great. I cant speak for much else. I also only use irons, but it shoots great for me. I can usually keep around a 6" group with the sights I have now. Im still trying to find the ammo my gun likes the best. No reliability issues, just get some flyers with soft point ammo. But just read a Tech note on Armalite's site that soft point bullets are bad because the tips get deformed when chambered and will greatly affect accuracy. This was made apparent when I chambered a round, then took it out to inspect it. I have been shooting Winchester Power Point lately in 150g flavor, and I must strongly advise to NOT use this ammo in an AR-10 or 308 AR, the tip had almost been flattened and had a slight angle to the tip. I did it again and the next round had smashed a bit of lead over the jacket itself. I can only assume this is very bad for accuracy. Shoots just fine out of my Remington 700p though. I only shot 40rds I think. No it was 30rds in the AR-10 and 10 in the 700P. Accuracy sucked out of the AR-10 but was great in the 700.

Ill find the tech note and post it here if Mr. TR does not beat me to it.

Let me rephrase my question.

What I want to know specifically is: How is the accuracey of the (lightweight chrome lined 16" barrel) IE great , good , fair, poor ?

I would like to hear from folks who are using this combination floated with a good trigger if possible.

Would also like to know your ammo and optic choice.

If you want accuracy in a light weight 16" carbine configuration, how about this. The MOA is 1".

Thanks Sinister
That is what I was looking for.

Amalite rep, I like the looks of that upper but Im trying to go light weight.

How much more does that barrel weigh than the light weight 16" ?

Thanks again

The upper is probably around 9 oz more the the standard 16" chrome lined barrel upper.
