What an odd looking ejection port/shell deflector.

[imschur]

yeah I have seen that on other brands as well. As a lefty I appreciate it :) Judging from the marks created during test fire at CMMG it works  ;D

[imschur]

Here it is mated up with my Colt lower

[Microgunner]

Damn....I like that. Give us a function report ASAP please.

Im thinking of dumping the stock handguards in favor of the Magpul MOE

[lmao_37]

thats a realy nice looking rifle  drool

[Microgunner]

I like the looks of that new fore stock.

[imschur]

I finally got the MOE handguards installed. The rifle looks fantastic. I like the MOE HG better in person than in photographs.  The fit is perfect and tight. Ill get a picture this weekend.

Ill get a picture this weekend.

With the new D7000?

[imschur]

Nah it's not even shipping yet. Rumors are mid October

Well, that's got to put a kink in your drawers. ;D

[imschur]

Im ok, it's once it ships I get anxious. Fortunately the D90 is an awesome camera in it's own right. It's like hot chicks. They are all good. Some just have more fun stuff. Yet in my unskilled hands the output will remain the same regardless.  :laugh:

I hope your photographic "output" differs (greatly) from your "hot chick" "output"!  :o

[imschur]

I have a fast shutter speed  :laugh:

[Microgunner]

Yeah, but I hear your hard drive is good for 50 shots, 100 if quality doesn't matter.

I've just bought this CMMG Sierra upper too. Has anyone had problems with a notched/standard hammer? Also, would this be picky on the magazine and ammo? I'm planning to use the Black Dog magazines that were designed for it, with Federal Champion ammo.

EDIT: I've exchanged it for the LEP upper. It works fine with my notched hammer and Black Dog and CMMG magazines. But, I always shoot slowly for accuracy anyways.

No ammo issues with the upper at all. And the Black Dog magazines seem to fit my Delton lower better than the CMMG even when they're fully loaded to the 10 rounds for CA. Also, both brands of magazines have the follower poke up high into the breech, so that blocks the bolt until you remove the mag, so that acts almost like a BHOA.

Heres an updated photo of my CMMG Sierra 

Thanks to FS2KSTD for helping make this project happen.

I see the MBUS are still attached.

You've got a quick release on the scope mount?

[imschur]

yep

That rifle looks GREAT D ... especially that sexy lower!  ;D

[imschur]

That lower is sexy as hell. The scope looks a bit funny but my eyes like it.

[asmurff]

I think the scope looks fine.  :thumb:

Can I get this CMMG upper with a 6" barrel?
