Thread: 450 Bushmaster upper

Just got my first 450 Bushmaster upper assembled

This one is subsonic only, pistol length gas system, 9.5" barrel, Aero Precision upper & scope mount 2-7 x 33 CDS Leupold, 7 shot mag.

AP front tube, the adjustable gas block is tuneable through the slots & the tube comes off with three cap screws which is handy,

Looking forward to seeing how it goes up the range tonight.



Weighs 3.34 kgs, 7.4lbs

Keen on your range report
would like to know how it goes so felt recoil and noise etc

Very nice

What sort of damage is it to handload .450? How well does it kill things?

Cheap enough to load for, brass is available, projectiles aren't badly priced especially compared to 500 S&W.

I haven't shot anything with subs, but seems to work fine, it's a big hole compared to 30 cal.

Waiting for a Mate who has a 450 BM & Blackout to compare their terminal performance.

I'm going to build a super only upper which will be a beast if my super bolt guns are anything to go by

Interesting. And looks good

So how much for the super version, upper only? Oh and some mag followers

No idea yet, no barrels yet, been waiting a while & will continue to patiently wait

Interesting

It might do, I have fixed the mag since then, the big flat nose was hitting the feed ramp a little low.

Will have another play & see what gives, it was holding open on last round.
