Expo Arms barrels

[1168]

Just looked at the 10.3, 11.5, and 14.5 on the PA website. Pretty cool that they list port size, and even cooler that they claim .070, .070, .077, respectively. Might be a good option if they shoot straight, are chambered right, have good threads, clean bores, etc.

I need another 10.3 with a .070 gas port like I need a hole in the head but for $85 it's awful tempting.

Where do you see that? Can you drop a link because I can't find it...

Looks like the price went up to $130 since I looked at them. At that price, I would just buy the 10.3 with crane spec gas port from Andro Corp. They're made by Ballistic Advantage and the one I'm running in my MK18 upper is a real shooter so far.

Thanks for double checking, I kept trying to use different browsers to see if I was missing a super deal.

I can confirm an Expo Arms 10.3" SOCOM profile barrel gas port pin gages at .070". I just did measured a buddies this past weekend. He could potentially have the cheapest 10.3" upper ever using semi-decent parts...$85 on the barrel, $59 on the BCG (he scored 2 when righttobear.com had those AO Precision BCGs marked wrong) and a BCM Blem stripped upper for $79.

Do you own one of Ned’s or PTG 5.56? gauges, or a silencer and an alignment rod? PM me if you don’t have a 556? gauge.

As this thread is primarily a Expo Barrel thread I will just throw in y $ .02 into it...
I am doing my first upper build ( I have bought all my others)
I purchased a Expo upper receiver and 13" Patrol handguard.... I must say I am VERY impressed with the fit and finish of both of these parts. They are very similar to a Zev/ Mega finish on the rail and the stripped upper.
I am very happy with them overall.... I was not a big fan of the aluminum barrel nut but as long as it holds up I will be happy.

I will be looking for one of their Combat handguards in 13" as they are rumored to be CMT.. but non the less these seem like quality components. If I end up with another 16" bbl ( like I really need that..) I wouldn't hesitate to get the 15" Combat rail they offer

If indeed they use Rosco re branded barrels.... is it just me or do Rosco seem a little heavy up front ( govt profile I know) but they just seem heavy to me ... which is ok, but it seems to swing differently, I tend to overswing my target...maybe I just need to change my Tampax and quit whining but... has anyone else noticed that about Rosco?
THey shoot very well and are gassed well..... just seem lil heavy

Rosco offers a couple different barrel profiles. M4, Government and Heavy. My 10.5 and 16 inch inch M4 profiles are not front heavy that I notice. My 13.7 stainless is a heavy profile and, well, its a bit of a tank in comparison but not objectionable at all. I haven't tried their Gov profile.
