I have a chance to buy a bushmaster varmiter or a red rock 223 for about the same price and was wondering which would be the best one to buy. i plan to use this to shoot 40 -50 gr bullets thanks

Since you said you were going to be using .223 w/40-50 gr. projectiles; I would say maybe not!
The reason I say that is because I am not familiar with the twist-rate on either of these models.
A 40-50 grain projectile lends itself better to a slower rate of twist. Ideally, you would be looking at a 1:12 twist-rate for these light projectiles.
Most AR type rifles are being made available in a 1:9 twist. This is too fast for that light of a projectile.
The original military configuration for AR-15/M-16's was for a 55 gr. projectile, and thus a 1:12 twist.
The current standard (A2) is in a 1:9 twist for the heavier 62 gr. projectile.
I am not familiar with the "red rock". I have a Bushmaster...and some other AR's.
I shot prairie dogs w/my 1:9 twist Bushmaster and didn't do very well. I would like to blame it all on the inappropriate twist rate for the light ballistic tip projectiles I was using, but know that isn't entirely true.
The 1:9 is better than the 1:7 I have heard exists, and the 1:9 is a happy medium...but I think the 1:12 is what you need if the 40-50's are what you are going to be using.
Over-stabilization can occur! Faster twist is not always better. Look up "over-stabilization" and you will see what I am talking about...do a search on "Google".
So, I would definetly look for quality in the rifle, but also consider it's suitability for your application.
