I am thinking of shorting the bbl on my AR 10T to 18 in. What impact does that have on the functioning of the weapon if all I do is shorten the bbl and nothing else? Should I give consideration to the the gas block size?

Quick sidebar: Shortening the barrel from 20" to 18" might have an impact on the cycling of the rifle since less gas is going to be vented into the gas port (the bullet has 2" less time in the barrel) and that could affect dwell time. I use the words "might" and "could" because rifle length gas systems are pretty forgiving. IF cycling issues occur, usually you can use a lighter buffer or have the gas port opened up slightly. Consult with the guys doing your barrel work and hear what they have to say about it.

:hijacked:

In cutting down a barrel, you will... I repeat WILL have to have the gas port on the barrel adjusted for proper cycling.

It's not the gas block, unless you have an adjustable one. Even then that helps restrict the amount at best and does not allow any more than what the barrel is already allowing into it.

Short barrels = larger hole and long barrels = smaller hole.

Hi LebbenB. Sorry I tried to reply to You . But did not put Your name to it. Rocky Mistake on Me. The reply has a # on it > #23096. But any way it was oil I had in it. But I will be changing over to royal purple. So , Today I got out of My work early and hit the range for 1 hour. I still had the old #9 oil in it , But it was oiled very good. I shot 8 rounds of fed. gold medal 175gr.308. had 1 stove p. Then I shot 20 rounds,That I loaded last week > 8 loaded with 168 gr. smk with IMR 4320 43gr. Then 6 loaded to 44gr. Then 6 loaded to 45grains. ALL went through the Rifle with NO troubles. Then, I shot 20 rounds of a new brand ( To Me ) Trajetech 308 win. 175gr.SMK. had 5 jams in the 20. It was very accurate, But did not like spitting out of My Gun. ( Stove piping ). So, I will now take down the gun and oil it heavy, Heavy ! With 10 W 30. And whip up some loads with Varget and 168 SMKs. I just can not get a hold of How My loads with 168gr. SMK can cycle better then 175 gr. SMK loaded by 2 other companies. maybe a few hundred more rounds and it will loosen up.

No worries, bro. What do the ejected Federal and Trajetech cases look like? ie, Scratches, dents, etc.

The same issue with two or three different brands of commercial ammo makes me wonder.
