I will probably have the rifle in a month or two since I have to wait for the barrel to come in.

I'll give you my honest opinion. Lots of money being wasted. Get a DI system and you will be good to go. I was also in their shop recently and I wouldn't let them work on anything that I own or anyone that I know.

In the end you will probably be hurt by what I said. It's your money so spend it like you want.

Don't worry I'm not hurt lol. I will see how much I like the gas piston system with this rifle and whether or not I would rather have direct impingement or gas piston if I were to buy another AR-15 in the future.

Prior experience with the platform? Reason for choosing the parts you list? Experience with the parts you list that would lead you to choose them?

[Iraqgunz]

Like I said, it's your money. Before you spend it I would look around here and read some of the stuff pertaining to piston vs. DI and what the pros and cons are.

If you don't mind. How much is this going to cost you? From what I could see you could almost buy two complete AR's for the cost. Or one AR, with light and optics with plenty of ammo and mags.

This prices up more than a Noveske Light Recce FSR. A lot of money for an idea that might not even run but then again, it's your money, not mine.

My suggestion would be to spend more time researching how the ar-15 system operates, who makes quality parts, and how the parts are supposed to work. Spend less time window shopping.

There are allot of things that I believe you have not considered.
A bolt on piston system has many problems, unneeded weight, harder extraction, more recoil and carrier tilt.
Some of your parts selections need more consideration billet lowers serve no real purpose forged ones are actually stronger the billets add extra strength by adding material that is unnecessary.
The RRA 2 stage triggers are notorious for loosing the first stage after a couple thousand rounds.
Another thing is the LMT enhanced bolt there nothing outwardly wrong with it but you are using it in the wrong application which might bite you. The dual extractor springs do not provide more extractor tension [ remember you are wanting use a piston kit the that has harsher initial extraction] instead they lower the spring K value in other words they provide longer service life not more extractor tension.
You are spending allot of money for useless additions that could be spent better in other ways MI sights are another example.
What are trying to do exactly? If you are trying to improve reliability you are going down the wrong road.

It seems like you are taking a lot of "next best" products and trying to put them all into one rifle. In all honesty, there are few things on your list I would personally buy, like the DD rail/barrel, BCM Gunfighter, ACOG and the VLTOR/Magpul stuff.

The billet lower can be forgone, like others said.
The RRA trigger is nearly worthless. Either stick with mil-spec or spend the $$$ on a Geissele.
The piston kit probably isn't anywhere near necessary. In my mind a low-cost retro fit kit is more of a liability than anything. Plus I'm not even sure if it will fit under the rail you selected (anyone?).
The LMT Enhanced BCG I think has been established as highly unnecessary. A BCM, DD etc. standard BCG will be more than adequate.

Also of note. You have a carbine gas barrel listed with a rail meant for a midlength FSP?

The rail IS carbine length. There are 2.5" of rail that extends out on the 3,6, and 9 o'clock positions. I chose it because it goes around the Adams Arms rail gas block. It fits the gas piston since I've seen one in person and it says on Adams Arm's website it works with it. I also chose gas piston because I find it to be much easier to clean.

I agree with you that I don't need the billet lower, but I liked the look of it and the integral winter trigger guard.

I liked the Rock River Arm's two staged trigger. I might upgrade to a Geissele in the future though.

Well we have shared our thoughts and this thread is going to end up like the others. A few of us asked questions and instead of just answering you pick and choose what you want to address.

So build your overpriced psiton AR and let us know how it works out for you once you eventually take possession.
