I don't have one yet, and have been trying to decide whether to buy parts to keep swapping out a .223 AR, buy a completed 9mm like Bushmaster's Carbon 15, or build a unit from scratch. (I'm just now exploring/entering the AR world. Don't have anything yet, but researching for first .223, as well as a 9mm to save $ for practice.)
I could provide cost to you but it would not be fair because I get everything at dealer cost. But if you go around and google and price all of the items I listed on my post and also include the cost of magazines and the lower reciever and lower receiver parts...as well as butt stock, pistol grip and rail pannels. You will get an idea of what it costs to build it.
Having said that, I do NOT suggest that you make your first build as a 9mm. They are largely custom jobs and take a little bit of fitting and tuning in order to get them to run perfectly. They can be problematic if you do not buy them as complete builds.
I made my selections based upon the following...in order of importance:
1. Durability and Reliability
I already had a Colt Match Target lower with large hammer/trigger pins. So I used that in my build. I knew I would need a DPMS type (neutered M16 hammer) because I wanted to get the bolt ramped for less wear on my lower receiver parts. So I had to go to www.m60joe.com
and get a large pin DPMS type hammer from him.
Then I had to decide on what mag block to get. Bolt hold open was a MUST for me so I went with Rock River. Cproducts has a new one that is just as good but it was not out yet at the time.
I got my bolt and other 9mm specific parts from the RRA web site. They are also one of the only carriers of the 9mm Gas Buster charging handle. The standard Gas Buster is not compatible with a 9mm bolt.
I chose the Yankee Hill light weight rail because the suppressor would fit inside of it and also because it is not expensive....and is very light.
I chose the Troy iron sights because they can be had in dark earth and are very low profile. They are expensive though.
I chose Magpul furniture because I like it and we are a Magpul dealer so...duh.
The Tango Down stubby forward grip is far cheaper than the LaRue FUG and comes in matching dark earth. I like the stubby because it works better for a CQB weapon.
I have Cproducts magazines as well as Promag magazines. Both work very well. Promag are synthetic, match color and are light...and cheap.
The TROS 5" barrel was chosen because of quality and the 3-lug feature. I wanted a pistol length barrel that has the 3 lug feature for my suppressor so that I would not have to worry about always having to check the tightness of the suppressor on a threaded barrel. Also the quick detach is nice.
The Aimpoint CompM2 was chosen because I hate the EOTech's shitty battery life.
I used the A.R.M.S. cantilever because a reflex sight is supposed to be far forward, not back by your face.
Hope this answers your questions.
