If you have not already sent your post ban rifles back to the manufacturer, you can send your post band back to get a pre ban barrel with A2 bird cage.

I know my limits...
I had a post-ban complete XM-15 (16" with short handguard). I sent it back to Bushmaster. I bought the same barrel assembly but pre-ban. The LABOR was free. I only had to pay for the part. I sent it back in a rag tag box with papers stuffed in it. Bushmaster returned in it a plastic case.
I know the barrel head spacing is correct and the test fired it.
I am just sharing info for those who still may have the post ban configuration.
If you can do barrel head spacing and swapping out serious parts, more power to you!Comment

My mistake, confused your situation. Read it wrong and thought you were going from a bayonet lug and flashhider barrel to one without the bells and whistles. Good on you!
I'm curious about the replacement barrel. Can you post a link to it or picture? Only reason I'm curious is because some of the new pre or after ban expiration barrels are not chromed lined but are 4140 chromemoly steel instead. Not a big deal really unless you intend to run your firearm hard core and under adverse conditions. Glad to here your happy with your experience.Last edited by Bayou Blaster; 02-16-2009, 02:09 PM.Comment

Start at 16" and longer ...
They sent back the old parts.
You can buy the barrels if you or somebody you know can install and get the headspacing right.Attached FilesComment

Thanks for the pic.
From what I gathered from the Bushmaster website at least the barrel is chambered to accept both .223 cal and 5.56 NATO. So it should have the correct feed ramps as well. It does not appear that it is chrome lined (Non chrome lined is a plus in the accuracy department). Barrel life should be in excess of 5000 plus rounds before accuracy starts to fall off incrementally. They just require a litte bit of extra care from experience. I prefer the chrome lined/chambered barrels, as the chrome chambers help facilitate feeding and extraction. BTW I own the XM-15 E2S. She's another one of my safe queens (Sad I know). Currently I'm looking for a complete upper assembly for another project. Hopefully next weeks Gun Show won't be as lame and overpriced as the previous ones I've attended here. May have to go to the next one in East Texas. They normally have more vendors and a better selection.Comment

Forget the gun shows...
Check out
Look through the vendors or suppliers listed across the top in the little boxes.
You will find a better deal there...Comment

Forget the gun shows...
Yeah I've been checking that website site out for years. Great resource of info at that site. Should probably join it as well. I'm looking at a Rock River Kit. Just haven't decided on barrel configuration yet. Every now and then you can find a deal at the shows that save you from having to use the plastic and paying for shipping. Sometimes you find people in there that are not vendors lookin to off load something. After I retired from the military, I managed a gun store for a living so I've still got a good awareness when it comes to vendors, manufacturers, quality of firearms etc... Too bad owner decided to retire/close business and go shooting with her husband full time for Smith and Wesson.Comment

Run Away As Fast As You Can
Not sure I would want to deal with them from the personal stories I've heard and reports I've read. Here's an example:
Your experience/mileage may have been better. I'm just not a gambler.
I also avoid anything with the name Hesse or Vulcan on it.
Same generally with Century (hit or miss). I do own an R1A1 (FAL) however that runs perfectly, but I completely tore it down and inspected it before purchase.Comment

I also own 2 x BMs, both are M4A3 Patrolman Carbines. They have chrome lined barrels and chambers. Very good rifles, once you re-stake the carrier keys. I also have a Colt 6920 and the Bushys have proven to be just as accurate and dependable.
Thanks.Comment

How do you like the 6920 compared to the Bushys? I have a RRA rifle and a Double star (they are just down the road about 45 min from me) pistol with a 7.5 inch DPMS upper. I am currently building my next one on a LCW lower. I have been looking at the 6920, and don't know if it is worth the money to buy the Colt. I know, I am going to make people mad, by saying that, lol, but from what research I have done, 95% of the parts are only really made by a couple of companies, and everyone else just puts their name on them.Originally posted by Long_Hunter View PostComment

Man! You guys are killing me!
Colts, BushMasters, multiple black rifles tucked away in the safe. Am I the only one who's married with kids? I guess I'm stuck with my little "frankenRifle" built from parts I've scavenged at shows and online auctions... At least until I can get a kid or two moved out of the house.:rolleyes:
I got the chromed 1:7 chambered in 5.56 (Planned to shoot heavier grains before I realized the price difference between a 55gr, 62gr and 77gr.... the 77's must have a gold filling)
How can I tell what grade of steel was used for the barrel? i.e. 4140 or not. Should it be stamped as such? It was a gunshow purchase so info was limited.
I've spent some time on AR15.com, but after about ten minutes my head is spinning trying to process all of the information.The 12ga.... It's not just for rabbits anymore.Comment

Most AR-15 barrels are typically made of 4140 or 4150 chromemoly steel. That is to say its a higher grade/harder grade of steel. The one in nine twist rate (one complete turn for every nine inches of barrel) is a good compromise. If your 1/7 barrel holds respectable groups at 100 yds with the lighter grain weight bullets then I'd say your good to good.:) The tighter twist rate was obviously designed to stabilize the heavier grain weight bullets.
As far as multiple rifles; my first AR-15 variant was an amalgamation of parts just like yours. Guess what? Most manufacturers subcontract/outsource a lot of their parts to other manufacturers. So in a way they are amalgamations too. Mine worked great. I modernized/refurbished it to the point you could not tell it from the original. It became my sons 18th birthday gift.
Most people don't build up a collection of firearms overnight. Sure I've had my "Got to have it now" firearms, but I recognize good deals when I see them. Many gunshops offer layaways (I've used this method myself before).
Unfortunately firearm prices may not go down even if the demand slows. Just like food. I've got some brand new safe queens when they were still very affordable. Some of these firearms are now worth upwards of 5 times or more then what I paid for them! Most quality well taken care of firearms don't loose value unless you pawn or trade them. Get those firearms now while you still can.Comment
