Free Floating existing barrel

Guys,
I have had this Bushmaster with a 20" H Bar flat top model since it was new hardly seen any action. It shoots okay but not like my bolt guns. I have looked at many of your AR's and I so want to have a custom gun for coyotes and smaller game. Here is my question, I am thinking of having the barrel free floated and putting in a new trigger to go along with the new glass I just bought. I am going to have the front sight removed and replaced with a low profile gas block. I am looking at coyotes and smaller varmints at 250 yards or less. I am trying to save money right now or I would just go whole hog and buy an complete upper the way I want. Your replies are greating appreciated. I am new to using a AR for hunting.
 
You should be able to get at least near 1MOA out of that bbl. A float tube will help, a good trigger will probably help even moreso. For around $100 I think the Rock River 2 stage is hard to beat. A plain jane float tube can be had for around $50, and simply take a dremel to that front sight base and you have a lo pro gas block for nothing (there's tutorials at www.ar15.com). The tube installation will require some special tools for the price of having a smith or armorer install it, you can probably buy an action block and armorer's wrench (you'll also need a torque wrench).

I've alway been of the mindset w/ AR's you spend your $ on the bbl and the trigger (assuming you use a float tube), the rest is just "lipstick and rouge".

Oh yeah, Welcome to Predator Masters!

I would probably put a good trigger in it and see how it shoots, if you need or want to float it do so. If it meets your needs/wants at this point then shave the front sight or install the gas block. If it doesn't meet your needs it will be much easier to sell with the front sight tower intact.
 
Here's my bushy flat top before it got it's paint.

I dropped a JP trigger (including the speed hammer) in there and was surprised at the improvement over the stock fire control group. I agree with Rabon that is your first step (or have someone do it if you aren't comfortable).

This rifle is free floated from the factory, and so is my other one, but many say that is a good next investment if yours isn't.

Also try different brands/weights of ammo too. My bushy doesn't like the winchester silvertips, or the remington core lock stuff, but drops ultramax 50 grain Vmax right in there.

Enjoy!
