This is my first AR and I decided to go with a BCM upper and lower from G&R. So far, this is what I've already ordered:

 

BCM upper, 14.5" govt w/ pinned 1.5 battlecomp

BCM bcg

BCM gunfighter mod 4

 

BCM blem lower

Magpul STR stock

 

 

I'm thinking of getting:

Magpul MOE+ grip

Troy 11" battlerail bravo

La Rue HK style flip sights

Magpul XTM rail covers or Troy rail covers

 

What do you guys think? I'm particularly interested in thoughts on the rail and sights. I'm having Paul from A-n-A doing the gun smithing. Also am I missing anything?

Get a lightweight barrel if they sell one in the config you want.

i was debating between a lightweight and govt for a while and was leaning towards LW, but G&R ended up only having the govt pinned in stock. Since the barrel is already pinned with the battlecomp, will it be an issue securing on a free float rail? i'm having trouble deciding between a 9" or 11" rail. Would a 10" rail cover the midlength gas tube?

you are building a replica of what i did...xcept i have a MOE stock and handgaurd/forgrip

Go with the 11", If the upper has a FSB and not a low pro gas block your gonna have to cut the FSB down so that the rail will go over it. Like this --> http://www.ar15.com/...page=1#i1847415 but you'd have to do it on the rifle because of the pinned brake (not really a big deal)

You can throw on a Troy Battle Rail Alpha without doing much outside of cutting the FSB down to a low-profile and removing the D-ring. I say go lightweight... unless you plan on mounting an M203 Grenade launcher in the future?

I did want the lightweight but it seemed to have a big trade off with accuracy and heat. Does the 6 oz really make a big difference?

There is no trade-off in accuracy, especially if the barrel is free-floating. Furthermore, the heat issue is not really that big of a deal as you're not shooting full-auto (and even if you were, you'd be surprised to realize the original M-16s had pencil thin barrels and were full-auto).

 

The whole point behind the Gov't profile was to accommodate a grenade launcher.

Got it. I will probably just have Paul file the FSB down. I do like the 11 rail but was worried about the work it would take.

 

Hmm I hear u devsadvocate. I'll use this barrel for now, but if it gets to be too heavy, I'll swap it out for a lightweight

 

Does anyone have the giessele ssa trigger? Is it worth the upgrade?

Hmm, I'm considering the SSA trigger too... but on the fence... I'll be looking to see what responses you get.

What ever rail you decide to use, make sure it uses the barrel nut that is already on your barrel. A 10" rail will be just short of covering a low pro gas block. I have the DD lite 10" with a vtlor low pro and it protrudes about 2 cm. I like the look of it better then the 11", it fills the space better between the rail and the barrel.

sorry for the lack of updates. so i decided i really wanted the LW upper so i had the govt profile sent back. i also was having an issue with the rail i wanted ant the upper being pinned, so i went with unpinned.

 

i went with the troy HK style sights, 11" troy TRX battle rail, and got a bunch of XTM rail covers. i'm holding off on the giessele SSA for now until i can make a better decision on it.

 

btw, how much does it cost to fix a pmag at 15 rounds?
