Hi guys, a friend recently sold me a AR upper for dirt cheap but the barrel isn't legal in ct off of a preban rifle. I'm looking at new barrels and getting some advise from my army friends, but they seem to not believe in budgets.

Can anyone recommend a decent barrel that would be under 200-250? CT isn't a fan of threaded barrels unless the brake is permanently attached, so a bull or rather an unthreaded barrel would be nice.

I've been seeing dpms barrels for 170 but a friend told me to stay clear. I want a hd and paper shooter, not a super accurate rifle. This is also my first AR so I'm not really expecting more than a beginner setup.

Thanks
Sean
 
the upper is an Oly A2 with a 11.5" barrel and 5.5" flash suppressor. CT laws do not permit any flash hiders and I have not found a long enough muzzle break to perm attach. I'd definitely go that route is someone can find a long enough MB for me.

If I get a new barrel I will sell the current barrel as its in good shape and perfect for someone doing a SBR or where flash hiders are allowed.
 
Olympic Arms upper

I'm wondering why your friends panned DPMS so quickly. Oly & DPMS are equal companies. Both Oly & DPMS barrels are from the same two barrel manufacturers. Wilson and Shaw make probably 90% of the AR barrels out there. Everyone uses them. I wonder what your friends were thinking. Or do they know what they're thinking?

To get a handle on real world pricing, go to Gunbroker and click on Firearms Parts & Accessories (don't click on Rifle yet, just the major category Firearms Parts & Acc). Across the top you'll see subcategories, including For AR-15, click that one. Now find the Search box in the upper right hand corner and type 'barrel'. Make sure the box Search Only In AR-15 is checked.

That should bring up 6 or 7 pages of barrels. Go have fun.



Note: Determine whether your receiver has the previous commercial style feed ramps, or the newer M4 style. Your new barrel has to match the receiver.

Alternate: You can buy a 5.5" fake suppressor and have it pinned on your barrel. Last one I bought was $12.

Alternate:
List your upper on this forum in the 'BuySellTrade' section, offer a trade straight across for an upper in CT configuration. The uppers are legal to ship from person to person. No ffl required. And you don't have to worry about matching feed ramp style.
 
thanks for the info. didn't even think to look at the ramps. looks like the conventional, non m4 ramps.

the friend that said to stay away from DPMS works as a gunsmith, but being a marine he expects excellence in everything. Every barrel he recommended was in the 4-600 range.


this is the barrel that catches my eye. Its simple and is CT legal. http://www.dpmsinc.com/store/products/?prod=373&cat=1917

"Your new barrel has to match the receiver."

Not necessarily true; you can install an M4 style barrel on a commercial receiver-- but not the reverse.
 
A barrel for you must cost 400 to 600?

I'm wondering if your friend the 'gunsmith' is doing you a favor with that advice.
For your use, that sounds like baloney to me.
A couple million other AR owners may agree.
Keep him as a friend, we all need friends.
But unless he's going to finance his own advice to you,
just smile and nod your head.

The barrel you linked looks good. Similar manufacturers are DPMS, Olympic Arms, Model 1, Double Star, CMMG, AR Stoner, Rock River, and others. Also, check out gun parts suppliers that have good prices like Brownell's, MidwayUSA, CDNN Sports, Numrich, and others. Go see what you can find.

haha, thats what Ive been doing. Funny how my buddys spend money when they dont have car, credit, and mortgage payments.


On another note. Will I need to mess with the head spacing with a barrel swap? I'll ideally be keeping the same carrier.
 
One of the fine design elements of the AR rifle is the use of a barrel extension between the barrel and upper receiver. If the barrel extension is installed correctly (get your barrel from a good source like the manufacturers listed above) and the receiver and bolt carrier group are properly assembled, the headspace is generally good.

But you MUST go through the normal safety checks after reassembly. If you don't already have books or honest online resources, go find them. They will explain the procedure clearly.

If you change your barrel, it's up to you to figure out how to do that safely.
It isn't like tying your shoes. Full and complete responsibility for safety is in your hands.
 
Yeah, ive been reading what I can on the procedure. Don't worry, when it comes to safety and proper procedures I'm good. I teach shop and would be missing a few digits if i didn't.
 
So I met a gunsmith apprentice at a buddy's stag party last night who works at one of the best shops in CT. We got talking and he said the dpms stuff would be fine for me. But then he caught me off guard a little.

He said he's converted a flash hider to a muzzle brake by welding a washer type piece of metal to the end. Is this something you guys would recommend?

I do have an extensive precision machining and tig welding background, having grown up in a metal shop with my parents. Something like this is very much in my capabilities but it just doesn't seem right. Opinions?
 
QuadKid -
Your question about welding a washer.
You can also put off road tires on an Indy car and call it a truck.
The tires fit, no question about that. But the utility just isn't there.
Flash hiders, compensators, muzzle brakes, and barrel crowns are carefully designed to maximize accuracy by minimizing the way the hot exhaust gas affects the base of the bullet as it leaves the muzzle. The washer welded in a flash hider may fit the Federal definition and be legal, but undoubtedly screws up accuracy.



Barrel listed at Sportsman's Guide-
I notice the twist rate is 1/7.
Much has been made of twist rate in these barrels, most of it is overblown. There is a slight accuracy difference with a fast twist (1/7 means 1 full turn of the rifling for every 7" of barrel) which makes it better for heavy bullets, not so much better for light bullets. That 1/7 twist will work for your plinking needs, but it would be better to get 1/9 for all-around satisfaction. 1/9 is the most common twist rate in commercial AR barrels. (Note: 1/7 is the US military standard, because their current ammo is steel core 62 grain, with heavier bullets for special uses. Sportsmans Guide is probably offering these barrels for those AR owners who want to be exactly like the Army.) 1/7 certainly works for plinking, but 1/9 twist works somewhat better over the whole range of available bullet weights. You can use either, it's up to you.
 
ants, i appreciate your help in this matter. Ive been thinking about this the last couple days and ive decided against it. I don't want to even consider legalities anymore. When i do finally make a move I will just get a new barrel like the DMPS one i posted earlier then sell the one i have now.
 
You could always take a file and do away with the threads on the muzzle. Touch it up with some cold blue afterward.
EDIT: Doh. Just realized you have a length issue too.
 
Hi, I'm new to this site. I'm recently put together a new upper and I wanna look into getting a new barrel for it. I'm looking for an 18" 1:8 to 1:9 twist black non flutted post ban barrel at a decent price. I've been looking around and really haven't found anything. A lot have the threaded end which I can't have in this state and most are flutted. Any one with any help I much appriciate it.
