Where can I find a:
20 inch 1/7 twist 4150 barrel
5.56 chamber
Chromelined is preferable
For under $150
Thx

Is this one close enough? It's a tad bit over $150, but I've had nothing but great luck from these folks. http://www.gmriflebarrel.com/gm-m17-...rel-1-7-twist/

I too have found GM barrels to be very good quality. Yes you can find cheaper, but there is a reason for the price difference.

Please note, that there is no caliber markings on the military type barrels ( you are looking for a M16 variation) if that matters to you.
I don't care about the lack of markings, but some folks do.

The cost is a few dollars more than you posted, but in my opinion, if you want to build a shooter, it is worth it.

To simply blast away, with "acceptable" accuracy, there are much less expensive options. If you want good accuracy ( many report less than moa) then a GM is a good choice.

Good luck, and have fun with your build
