I bought the complete Bushmaster rifle. It has a fixed A2 stock, so the buffer tube would be a rifle one. I figured I would go this route because I expect the lower would be made to match the .450 upper in terms of operation. Now I did stick the .450 upper on a Del-ton sport lower which has a carbine adjusting stock and carbine parts. Recoil has more noticeable on the carbine lower. Also that lower has movement in the stock so accuracy was affected.

Recoil isn't a problem for me with this gun so you could stick it on any lower and shoot it. I believe there are two builds for this gun and it relates to barrel length.

For me I wanted to get the most accuracy and velocity out of this gun. The 20 inch barrel gives me that. I want to reach out to game out to 200 yards with max ballistics. I have brush guns already but nothing that is legal to hunt deer that will shoot this flat.

If I was more geared to making a brush gun then I would go with the 16 inch barrel. I have no issue handling a 20 inch version in the brush but a 16 inch would be better suited to this role. This would be great if you already had longer shooting rifles for hunting, or if all your shots are close.

Hope that helps.

Well guys the .450 Bushmaster upper got dropped off by the mailman today, I also received my Burris 2x7x35mm fullfield ii scope. I ruff sighted it in at 40 yards this evening, my 1st impressions as i shouldered and shot it, is it should be a good little deer brush gun it's lite, short, quick, powerful, and it hardly kicks. My boy fell in love with it when he took a shot also. Mine is a 16 inch barrel and i put it on a standard Bushmaster.223-5.56 lower.

A 2-7 scope should be great for it.

gjersy, that cartridge is about as perfect for most the places you hunt as can be.

Here is some shooting I did this afternoon. .450 bushmaster and a bolt action Savage 7mm-08. I was surprised that I grouped better with the 450. I shot with bipods on cold dirt and had my scopes dialed down to the lowest settings. I used factory ammo for comparison.

Thinking that Savage doesn't like what you were feeding it too much. Still, not too shabby for 150 yards.

Wow good shooting d80hunter, glad you talked me into getting one lol.

I broke out the chronograph today and checked some velocities today. I brought the muzzleloader too since the .450 bushy and the .50 cal muzzleloader are shooting the same Hornady 250 grain FTX bullet (.452 diameter same B.C. & S.D.)

.450 20" barrel clocked in at 2238 FPS

CVA Optima V2 .50 cal 26" barrel got me 1635 FPS with 100 grains Triple 7 pellets.

I need to try 150 grains next time I break out the chrony.

*the 250 grain Hornady SST 20 gauge slug advertises at 1800 fps*

Totally pleased with the results.

I have this .450 Bushmaster. The 250gr FTX just hammered a decent buck opening day for me.

Nice groups. Are your reloads much better than the Hornady ammo?
