Ordered some parts for a 450 build!

[armyturner]

I finally made a decision on the direction of my 450 build. Ordered a MEGA 3H billet lower, SBU billet slickside upper, billet charging handle, and hogue grip. I traded one of my 450 barrels for a Larue 7.0 rail and a VLTOR Modstock, so I have the majority of the parts covered. Still have to come up with a bolt. MEGA said that the upper would be about 3-4 weeks, but the other parts would ship right away, so I can at least have the lower ready. This will be my first complete "from the ground up" build, so I am a little excited.

Oh MAN!! We tried to warn you and now you're going to be bit by the 450 Gods...Oh Wait, You Already Have Been!!

Sounds like you are well on the road. If you have any trouble getting a bolt and you might (I can't believe how hot the sales have been!). But here's a solution, take any 223 bolt to a local machine shop and have them open the bolt to accept the 450 rim (The exact size escapes me just now, but we'll have that answer soon). You can use an extractor intended for the AK round, you just always have to let the bolt slam closed. Now you're in business and after all that we better hear all those tall campfire tales, about your escapades with the rifle..

As a recent "addict" to the 450B craze, I gotta tell ya, building your own black rifle is extremely fun, yet with the current "parts" shortages, can be an endevour of patience. I've been waiting on my parts since 3/01/2011. Meanwhile, I have scrounged up some standard lower parts from DPMS just so I could make my Thumper operational until my competition parts from Bushmaster arrive.
Welcome to the campfire!
