View Full Version : Question about BCM upper and featureless build

I'm considering a lightweight, featureless AR build and have a few questions.

I'm looking at this for an upper:

http://www.bravocompanyusa.com/BCM-Standard-16-LIGHT-WEIGHT-Upper-Receiver-p/bcm-urg-car-16lw.htm

But am concerned that it has a flash hider. How do you tell the difference between a flash hider and a muzzle brake? It doesn't specify anywhere on that page, as far as I can tell, as to which this is.

My second question is related to the BCG/charging handle. If you add it from the dropdown, it says it's an "auto" BCG. Is there any issue with having that in a featureless build?

Thanks for the help.

looks like a standard A2 flash hider. I wouldnt use this on a featureless rifle.

No issue with a Auto carrier vs. a Semi-auto Carrier. you're GTG here.

It's hard to visually identify a brake vs. flash hider from a distance, but up close you can generally tell the difference by looking at the channel of travel for the bullet. Flash hiders typically open up immediately following the barrel so gases can expand and cool. Brakes usually maintain a much tighter diameter around the bullet. If you're looking online, I would simply go by the description given by the manufacturer.

Its an A2 unless you buy a 14.5 in which case you have a few options. You are GTG on the Auto carrier vs the semi.

The only thing that should concern you is if you are building a featureless rifle. In that case you have to go with a muzzle break or compensator of some sort. If its going to be used with a mag lock and 10 rounder the A2 is just fine.

I picked up the middy one of those last month. Yes, it is a standard A2 flash hider. But it takes about a minute and a half to swap it out for the muzzle brake of your choice. Just get one with standard threading. I like the ones from Cavalry Arms, as they are in the $20-25 range, are about the same dimensions as a standard FH, and they actually do reduce the muzzle climb a bit. If you have a vice and a wrench, you can usually swap it out at home.

Also, a manufacturer like PWS will have a PDF on their site that contains a letter from the ATF stating whether the muzzle device does or does not reduce muzzle flash.

I have only checked on their site, because that's what I had, but I'd bet the others have copied letters also.

The CA DOJ does not recognize the PWS556 as a comp but a flash suppressor. Its a no no to have on a featureless build. The DNTC and TT are GTG though.

PWS is the only company I have seen to produce such letter and if its not from the CA DOJ it doesnt mean much. Just because its federally recognize as a comp only, CA has there own interpretations of things.

As long as the muzzle divice doesnt claim any flash suppressing qualities or equal to that of an A2 and says its a comp, you should be GTG.

Wow, thanks for all the quick replies.

That sounds like a winner then if I just swap out the flash hider for something else.

While we're on the subject, does anyone think I should be looking elsewhere at light weight uppers or is this one the way to go?

I'm planning on using the hammerhead with this configuration:

Using the same stock (http://www.parallaxtactical.com/store/ace-ar15-ultra-lite-stock-entry-768.html), so I want to keep everything light and balanced.

@ teIam - Get that upper, remove the flash hider, and install a Battle Comp. Muzzle brake. It's been CA approved to be a compensator.

I have one on my DDM4 upper.

Stick with the BCM lightweight.

I really like the way the Battle Comp looks. I wouldn't mind going that route.

It kinda reminds me of a triple tap.

Ditto . . . That is the route, which I chose. Recently, shortly upon receiving my 16" BCM BFH middy, I mounted the said in a vise and changed the A2 FH to a Battle Comp 1.0. Gotta love it. ;)

I used a YHM muzzle brake, not only was it affordable at $25, it specifically states it is NOT a flash hider.

Sorry, one more question for you guys.

With the setup I posted above, this will be over 30" long, right?

Yes. My 16" with sopmod stock is about 33".

I don't think there's any combination of parts you can put on a standard AR that will have the 16" minimum on the barrel that will be less than 30" overall. The buffer tube + 16" barrel is more than 30".

This config is about 32" from tip of the muzzle device to the back of the pistol tube, and 36" or so to the back of the buttpad.
