It's my first post on here so I thought I would start out in the place I will likely spent most of my time, the Retro section!  

About a month ago I traded my dad a RRA LAR-15 for this Windham made, ban-era, XM15-E2S. It was made during the ban so that means no muzzle threads, 10 round magazine, HBAR, semi-auto cut BC, and no bayonet lug. Before I was into shooting all I knew about this rifle was that it was really heavy and was really unreliable.   

Here is how it was when I got it:


  
After getting hold of it I decided I wanted to bring life back into this old rifle and make it into an A2 clone. Really the only way I could start changing this rifle and not trigger my OCD about my rifles being company matching was to send it to Windham Weaponry and have them re-barrel it. I had them re-barrel it to a correct A2 profile with bayonet lug. Windham Weaponry people are awesome by the way, they really went above and beyond my expectations with this whole thing. I told them I wanted a full auto cut BC put n while they had it and they gave me a brand new complete BCG while only charging me for the carrier.

Here it is now:





Out of the 7 AR-15's I own this one now means the most to me.  

Now that this rifle is done I have moved onto an M16A1 build. Using mainly Brownell's upper, lower (getting really impatient with this one), and barrel. All of the small parts I have got from Amherst Depot, another really great company.

I hope my first post wasn't too boring for you guys and I look forward to the advice you all give out!

Excellent first post sir, and welcome to the site. 

Very nice rifle.

You chose the by-far best variant. Looks excellent. My first was a 20" A2.

Theres an a2 forum here if you didnt know but welcome

Awesome to resurrect an A2, it looks great with the flash hider and bayonet lug. A2's are great shooters and many consider them retro; 1983 was a long time ago.

Be sure to keep us posted on your A1 build.

Sweet!
