That does seem like a pretty good deal. I think that's about what I have in mine including the red dot site. I also went with the M4 ramps and matching barrel. My barrel is a 1 in 8 twist which allows you to use a heavier grain bullet, just some FYI.

 

compared to a 1:7 or 1:9?

 

The 1 in 7, I also noticed the specs one the set up your looking at comes with a chromed line barrel and the full auto bolt carrier. Unless you are a competition shooter you will never wear that barrel out and will make cleaning a breeze. The full auto bolt carrier is exactly what you want. I waited for quite awhile for that bolt group to become available at BCM, (Bravo Company Manufacturing). As far as receivers go there only a few company's that are authorized to make them. Check out CMT (Connetitcut Machine and Tool) and LMT (Lewis Machine and Tool). They both supply all the major brands. Hope this helps.

I'm sure Sexynerd can provide more insight as well. Keep me updated on what you get. Good luck, you will love it!!

 

Oh alright, I dont get why you can use a heavier grain ammo?

Also, the kit and the assembled rifle both have "Forged 7075-T6 A3", yet the descriptions are slightly different so I am not sure if they are identical or what. It really pisses me off that the already assembled rifle seems to be a better deal. You would think I would save money or at least break even by building it myself.

 

the full auto bolt is the same as the semi auto bolt.

 

Im looking for a 1995-99 f250 or a cummins and gonna putting a 6inch lift on it. It would be sick to do. I want something to haul my quad around too

 

you can buy my 02 f 350 powerstroke 10k and i will bring it out to you

 

I found this to explain the twist rates.

The common twist rate in civilian Ar-15 is 1/9 twist which is a good compromise. You can shoot 50gr-69gr bullets. To shoot the heavier 75, 77, 80-or 90s which are popular in long range competitions you need a 1/7 or 1/8 twist. Now if you are going to use this rifle for varminting then you want to to have a slower 1/12 or 1/14 twist to stabilize the lighter 39-55 grain bullets. If you are going to be punching paper at moderate ranges then a 1/9 is fine but if you want to use the heavier bullets than a 1/8 is needed. Most bull barrels for the AR come in 1/12, 1/9 or 1/8 rates.

 

And this link shows the differance in bolt carrier groups.

Thanks. I still may go with a 1:7, idk yet. I'm still pissed off that I seem to be getting better parts by buying an assembled rifle.it should be at least the same price to build it myself.I an still waiting on psa to get back to me about the specs on the rifle kit upper.I asked if has the m4 cuts/feedramps because it doesn't list it like the assembled rifle does.
