I really like the BCM RECCE-16 rifle and the Daniel Defence rifles like it but there are several things I don't like and I can't find any company that makes exactly what I want. I have never built an AR so I am not sure where to begin.

I want a 16 or 18 inch heavy or government profile barrel with a 1-7 or 1-8 twist. I would like it to be sub 1.5 MOA with a normal quality ammo. I want either stainless or chrome lined to help with ease of maintainence. I would like mid or rifle length gas system

I want either a monolithic or free floating quad rail mid or rifle lenght hand gaurd to help with accuracy.
I don't want a front sight tower. I want folding BUIS.

I really like magpul stocks and grips

I don't like how the standard buffer tube weight seems to rattle when firing so I am looking at a product from JP Enterprises. It looks like they also sell some nice barrels.
I was thinking of a LMT bolt carrier(JP barrels come with a bolt).
I have started to save to buy or build but not sure what to do...
Do I buy a built rifle and add a few things... Or do I build what I want from the ground up???

And where do you start when you build an AR?

The rifle idea I want is similar to the navy seal RECCE or army DMR rifle.
It must have a collapsible stock.

You start with a quality lower receiver and build from there. There is plenty of info on the AR forums about lowers and which ones to stay away from. After that it is one piece at a time until you have the AR you want.

^^This.......good quality lower and put what you want on it. They are easy to build.

any ideas as to which companies lower is the best quality to price. maybe colt. bcm. i am not surewhich company to go with to acheive the best fit between the upper and lower.

A freind of mine went with a Yankee Hill when he was building his AR and it turned out great. There are only about 4 companies that actually make lowers and then resell them to the others who put their names on them. I'll try and get you a list of the parts he used along with the prices he paid so you can get an idea of the cost you are looking at.

Got the list. OK to email it to you?

email away my friend. i want to have a tight fit between the upper amd lower because when i am done i am hoping that with match ammo i can get one moa groups or better. it looks like may of the military and match shooters are using a one in eight twist for the best groups with a wide range of ammo weights. i like the lmt socom stock or a similar magpul stock. do you know anything about the two different gas tube sizes. it looks like there is a point seven five zero or point nine three five dia option.

Parts list sent.

Haven't seen anything about different size tubes but I'll see what I can find out.

i wonder if i should use a flash hider a muzzle brake or a hybrid set up
