I had to back out of the Bushmaster 450 upper purchase for the time being. But I may be able to swing a barrel and bolt from MGI. I've read up on what I could here on them...but not much conclusions to what I found. So If anybody has this set up and can clue me in that would be great.
Questions:
1. What size gas block does their barrel require?
2. Are their barrels chrome lined like the bushy?
3. Looking at the picture of the barrel on their website, it looks like a really short distance from the barrel extension to the gas port...maybe an illusion?
4. Any feed ramp differences between the two?
I have an extra billet upper receiver that is not in use and a few other spare parts, so if I can go this route and save a boatload of cash...this will be my best bet .
Thanks
ps..I have sent emails to MGI with my questions with no reply yet....
