Mega or DD Lower?

[01tundra]

Here it is, won't be able to get out to the range until this weekend.....

The upper and lower fit so well together that I can now feel a little movement in the CTR stock, when it was on the BM it felt solid. Not sure if I just got lucky or if all the BCM/DD combos fit so well together.......

BCM 16" lightweight middy upper
Daniel Defense LITE 12.0 rail
BCM Gunfighter charging handle (medium)
BCM BCG (auto)
Colt LPK
Colt receiver extension & castle nut
Sprinco "blue" spring w/ carbine buffer
Geissele SSA trigger
Daniel Defense QD rear sling attachment plate
Gear Sector front rail sling mount
Vickers padded sling
YH Phantom FS
Troy Tritium HK folding front sight
Troy Tritium Di-Optic folding rear sight
ACOG TA33G-H (w/ Butler Creek Blizzard lense covers - sizes 1 & 3)
Harris BRM-S bipod w/ Larue LT706 QD mount
Magpul CTR stock
Magpul MOE grip
Magpul AFG
Magpul Enhanced trigger guard
TangoDown rail covers

Looks goood. I have this same upper arriving tomorrow, how do you like it? Do you notice the weight savings?

It "feels" light, I meant to weigh it and my BM carbine upper to get an idea of what the difference was. It feels about the same as the carbine does to me, but the carbine also has a DD Lite 10.0 rail on it.

I have a BCM 16" lightweight upper with FSB, you can notice the weight savings vs a govt profile. The barrel is machined more towards the end so its noticeably less front heavy feeling.

That thing is Bad A$$!

Finally made it out to the range yesterday. Got the BUIS & Acog sighted in short order and then ran 300 rounds of XM193 through it without a single hiccup.......smooth as silk !

I was running my blue Sprinco spring and carbine buffer, so when I got home I decided to give the "H" buffer a try, I wanted to see how the buffer would run in a dirty rifle. The recoil was a slightly less, as expected, and every time I would hold the rifle with one hand (away from my shoulder) it would lock back with no problems.

Next I wanted to compare where the shells were ejecting so I threw the carbine buffer back in, then went back to the "H" buffer. With either buffer the shells were almost landing in the exact same spot - right around 4:30. So now I'm wondering if I should stick to the carbine buffer to make sure I have the most reliable system, since 4:30 is right at the edge of short-stroking from the charts and info I've read...............

I like your style! I'm an all black man myself

I've never heard of this before. I have an AR that works fine that ejects at 2:30

Your fine as long as you are not short stroking with some of the weaker ammo PMC and others. I wouldn't worry to much with the ejection pattern because it will start clocking forward the ejection pattern after 2-3k rounds.
