First AR15 Build. Thoughts, Ideas?

[ColdDayInHell]

Actually the under 6lb one but thanks for that one too.

Random mil-spec upper and lower, carbine buffer, tube, and spring, random mil-spec parts kit (except for the trigger)

Here's what makes it light:

This stock: http://shopwilsoncombat.com/Super-Stoc-Carbine-Buttstock-Black/productinfo/TR-SUPERSTOC/

This forend: http://www.midwayusa.com/product/22...rail-modular-free-float-handguard-ar-15-black

I used a Shrewd muzzle brake, the smallest low-profile gas block I could find, lightweight Leupold 1-4X scope, and this trigger:

ETA: The barrel above is a 6.8 SPC. I built an additional upper in 5.56 using the same Wilson Combat lightweight profile barrel (and the same other parts).

Pretty good deal as it comes with the UPK too

The upper comes unassembled, but complete with BCM forward assist assembly and ejection port cover door assembly.
Features

• Machined from 7075T6 Forgings
• Completely Assembled
• Mil-Std- 1913 Rail for mounting optics and accessories
• Machined for use with barrels that feature an M4 barrel extention
• Round Forward Assist

Figured I'd give another update. I ended up going with the mid length 14.7" PSA complete upper. I ordered it but it will still be a few weeks till I get it. The last part I need is an upper which is easy. I'm waiting for Precision Firearms to finish theirs hopefully by the end of this month so I can take a look. If not I'll probably get a PSA lower too.

Lastly, all i should need is a set of low profile flip up sights and an optic. The optic is between an eotech and an aimpoint but I haven't even really begun to look at too many of the options yet.

Primary Arms is having an Eotech deal right now for SHOTshow, and I think Opticsplanet is having a sale as well. And I think the Eotech $60 rebate is still going on too.

I'm an Eotech fan myself, though I don't have much experience with the newer smaller Aimpoints like the T1 or the Pro. I have used the older M68 and the newer CompM4 version, and I'll take an Eotech any day over those. The CompM4 is a big chunk of metal for just a red dot.

I'm really not sure on the optic. I have used an eotech before, mainly just checking it out and I liked it. My friend who is going to help me with the build has both and told me I could try both. He has an eotech, aimpoint pro I think it is, and just got the aimpoint M4 but I don't think I'll be getting the M4.


Sights I'm back and forth on since they are just backup. The Magpul are a reasonable price and only about $100 for the front and rear. I see most people just say go with Troy's which are about $170 front and rear if you get them from the right place.

Those troy buis sights are awesome, but i cant afford $170. I only need a rear flip up to go with my red dot that will cowitness my front sight post. anyone know of a flip up rear sight for around $20 that is reliable??
