Can anyone verify the following statement on Bushmaster's Web Page?

We sell only new bolt carriers - no rewelds or remakes. The bolt carrier assembly is the “heart” of your weapon - with the most critical machining tolerances of any component in the rifles system. Ours are manufactured to mil. spec. and are magnetic particle inspected to insure against cracks or flaws that could cause catastrophic bolt failure or injury.

I was sure that I read somewhere that nobody did MP testing on Bolt Carriers.

Thanks,

They're most likely referring to the actual bolt, but I didn't know Bushy tested them at all.

I don't even think Colt MP tests the carrier as it doesn't go through the same forces as the bolt.

Absolutely and if I'm not mistaken?...Their M.P.I. Dept is located right next to their..."All Bushmaster Rifles Are Laser Sighted Before They Leave The Factory"...uhem...Dept.

This is the description in their catalog and Web Page in regards to a Carrier w/Carrier Key only, not a complete Carrier/Bolt assy.

I thought maybe someone had purchased one that came with an MP marking, but I also thought it was probably too good to be true.

And....Since this is probably a misprint on Bushmaster's part -

Do any of you know where I can get a new CMT or LMT Carrier W/Carrier Key?

I don't want the complete assy, since I want to buy a MP tested Bolt to pair with it.

Thanks,

Grant at G&R Tactical has CMT bolts that are MPI'd.

Get in contact with him and see what kind of price he can give you for a CMT MPI'd bolt and the carrier assembly.

There is lots of conjecture, but very little first hand information on how BM makes their products. AR15.com is a misinformation nightmare when it comes to the inner workings of any company. Not to mention all the petty agendas at work.

Call Bushmaster if you're really interested in their fabrication methods
