My BCM Midlength AR-15 Carbine Build

[TGO David]

I'll be using this thread to journal my midlength AR-15 carbine build.

Components:

• CMMG lower (had this lingering around)
  
• Bravo Company Machine (BCM) BFH 16" Mid Length Upper Receiver Group
  
• Daniel Defense LITE 12" Handguard
  
• BCM auto bolt carrier group
  
• BCM Gunfighter charging handle, MOD4 (Medium) latch
  
• BCM milspec buffer extension tube
  
• G&R Tactical trail-mix lower parts kit
  
• Battle Comp 1.0 black oxide muzzle brake
  
• Magpul ACS black milspec stock
  
• Magpul MIAD black pistol grip
  
• Magpul AFG angled foregrip -- Joe's favorite
  
• Magpul backup iron sights (front and rear)
  
• Vickers Tactical 2-pt sling
  
• MI HD quick detach swivels
  
• American Defense Mfg (ADM) Recon 30mm optic mount
  
• EOTech OPMOD 1-MOA twin-dot RDS
  
• Your mom
  

Update 2011-01-22:

I have assembled the carbine save for the optics. I have also decided to standardize on the same optic that I am using on my short barrel rifle, so I am going to skip using the Trijicon TR22 and instead use the EOTech OPMOD red dot sight. If at some point I decide to use a magnifier, it will be easy enough to implement a flip to the side magnifier behind it.

Also, I am adding two photos taken this morning.

I put together a BCM midlength gun for one of my friends a few weeks ago. He ordered his Daniel Defense rails a few days after he ordered the kit so they arrived after I got the gun finished. He thought he could switch the rails out himself, so he tired to use a pipe wrench to get the barrel nut off. As you know this ****ed up the nut in a major way. He called me and asked if I could help him so I took my AR blocks and AR tool up there and we finally got the barrel nut off. The DD rails are super soild and the midlength balances perfect. Looking foward to watching the build come together.

You gotta give us a report on the Battle Comp. I was looking at those again today. Looks like the best compensator out there. My next tweak after I recover from my $900 sling purchase

EDIT: Aw hell. I guess we can both give a report now. Battlecomp is out of stock on the 1.0, but they have them at BCM. My girfriend is gonna shoot me.

Sweet. Please post pictures. I have been looking for a BCM 14.5" upper, to go with another lower that I've got, but damn it if they aren't always out of stock. I guess that I just need to call and get going with the waiting process.

Everything aside from the ADM mount and Trijicon will be here next week. The Batte Comp 1.0 arrived today via USPS. Holding it in my hand, it sure as hell doesn't feel like $150 ... but we all know the magic doesn't happen til you start running rounds through it.

[mikegideon]

I've been drooling over the Battlecomp for months. Went through the videos again right before you posted this thread. Can't wait to get it on the rifle now.

[TGO David]

I have edited the first post to add some photos and to also add an update of sorts.

[Raoul]

Let's go shoot it.

Well if you don't want a suppressor, that's fine, but I don't understand going in the complete opposite direction...

Keep us posted. I've always loved the middys and that one looks badazz.

[TGO David]

Let's go shoot it.

Giggity.

Actually, I plan to go shoot it tomorrow. I've got a full plate today.

[mikegideon]

Pretty stick. The muzzle looks just like mine Where is your front sling attachment point?

I shoot rifles left-handed, so it's on the right side of the forearm as close to the rear of the forearm as I can get it.

Thats a very nice rifle! This is the first I've heard of the Battlecomp. The videos are pretty impressive.

[Jasongar8]

I'm interested to see how you like the Battlecomp. It is supposed to work as well at the KAC Triple Tap at about 1/4 the price.

[MacGyver]

That's really nice!

Just shot mine today. You're gonna love it. The rifle doesn't move off the target. Take extra ammo... we ran out way early.

[Raoul]

Take extra ammo... we ran out way early.

My new motto!

[mikegideon]

I had smoke coming out of the handguard, so I gave it to the lefty chick (1st time AR shooter) to let it cool down. After the first few rounds, she was rocking it too. Since there's almost no recovery time getting back on target, you're just gonna wind up shooting more. I love it when a product lives up to its claims.

I'm curious as to how you like the AFG? It seems like a genius idea, but I've never been able to try one out. I'm thinking of adding one to a build (non-AR) I have in progress.

Thank you.

It works great. I'm ordering another one for my SBR soon.

That's really nice!

Danke.

The AFG makes perfect sense on a carbine as it requires your support arm be at full extension to maximize the benefit of natural bio-mechanics. I've seen a few run on short barrels and wondered WTF the person was thinking as a regular vertical front grip makes better use of both your muscular-skeletal system and physics, and presents a smaller shooter profile... but to each their own.

[TGO David]

I had smoke coming out of the handguard

That worried you?

[mikegideon]

That worried you?

Yep... worried about running out of ammo.

[TGO David]

Yep... worried about running out of ammo.

Understood. The gas tube running beneath the forearm makes a nice hand warmer.

[mikegideon]

I could have probably put it a little better. I usually get some smoke. In this case, I wasn't trying to push the rifle. Followup shots were just so easy that smoke was a natural byproduct. But, I don't have to explain that to you .

I started out on a rest to sight in the Eotech. It's the first time I have had a rifle stay on target after a shot. The thing just works!

[TNRat]

That's a nice rifle. The way you shoot makes my back hurt.
