In for 1!
I plan on getting a Troy TRX Extreme 11" rail but am not sure which gasblock I should go with? Any recommendations?
ordered :D
Ordered. :D
Thanks, Paul!!
ooh those are sweet.
i used to have a light middy. it's a great setup.
Anyone want to buy a regular middy with a couple hundred rounds through it? :D
The problem is there aren't many gas block actually AVAILABLE for the 0.625" barrel. After a long search, I found and bought the Midwest Industries gas block. It's serving me fine in my 16" Daniel Defense lightweight barrel assembly.

Oh, and the 11" Troy TRX Extreme is super nice. :)
I believe the BCM does not require the .625" for that very reason.

VLTOR makes a 0.625" gas block.
Can anyone remember how short of a length BCM plans on making their lightweights?
So someone school me. What are the advantages of a lightweight upper? Is it purely weight savings? Is the rest of the upper built to the same specs as all the other BCM uppers? I am in the market for an upper for a lower ive had in the closet for quite some time.
It's just a pencil barrel. You don't notice how skinny it is? :D
It saves weight and should hold up just fine for the normal wear and tear, It's the profile of yesteryear, history does repeat.
So if you're looking for a simple light practical no BS rifle it's a good upper for a good build. If you plan on mounting lasers and beer can holders I would go with an HBAR :P
Are these CHF or standard rifled barrels, not that its that big of deal. ?
I was thinking about going with the Vltor Gas Block in .750" diameter because I was under the impression that is the size of the barrel at the gas port. Has anybody verified this information? From the pic it does not look to be as skinny as the DD barrel.
Also, I see that Vltor has the choice of set screw or clamp-on. Which is preferable in this situation? The gas block will be covered by the Troy rail.
According to Paul in this thread, we're looking at .750" under the FSB.
So, the barrel is just a pencil barrel? The rest of the upper is the typical BCM upper? How will a pencil barrel hold up for strings of sustained fire? Is it something you would want to run through a strenuous course of fire, or is it more for target shooting and a few hundred rounds here and there? Also, with a free floated rail system it wouldnt so much matter what you put on here as it would have no impact on the barrel correct? You just wouldnt benefit from the pencil barrel im guessing. At most, i usally add some XTM panels and a good light along with BUIS and a sling.
pencil barrel with a .750 gas block (for parts availability reasons). Pencil should be fine for semi auto shooting. The barrel will heat up faster due to less metal but it does cool down faster because of less metal. The M16A1 was pencil barrel even.
My (wife's) upper showed up today. I don't know what all the fuss is about with the taper pins. Maybe it's all an inside joke, maybe Starting Strength has given me super human strength, maybe Paul's getting soft on us DIY-ers, who knows. I gently clamped the upper down on my bench, front sight tower on the new Brownells block, wacked the pins 4 times each with a 3/32" nailset & 20oz hammer & the job was done.:D:eek:
All the talk about these pins being a pain to get out had me kicking myself when I saw that Bravo Company is offering the upper with the 11" VTAC rail installed for $625.
Now I just need to wait for the rest of the parts to show up.
mine should arrive soon
mine came in today, messed around, definately feels a lot lighter. I put it on my A2 stocked lower to get an estimate on the weight feel. Cav Arms lower will be 1 lbs lighter. Definitely moves the center of mass towards the shooter.
The portion of barrel under the handguard is still govt profile with some extra milled off behind the front sight tower. Is this the normal way lightweight barrels are machined? The area of the barrel in front of the sight tower is the .625" I think. Its thinner than the govt profile part. I guess under the handguard it might be too weak to make this .625" also.
comparing with a delton 16" middy HBAR, BCM 16" middy lightweight, BCM 20" rifle

So how many rounds fired are we talking about before accuracy suffers due to barrel heat with the pencil barrel? 15? 30? Will this come into play in a carbine course? An how fast is cool down?
What's the weight savings compared to a regular 16" middy?
i don't have a scale. Daniel Defense said their M4 pencil vs M4 govt was a 6oz difference. Im assuming it will be a similar figure for the middy even tho its BCM. Its also weight saved towards the end of the barrel so it moves the center of mass towards the shooter more instead of it dangling at the end of the barrel
Lightweight will cooldown faster because its less metal to cool, but it will heat up faster. Well it is govt profile under the handguards so I dont see its heat properties as any different than a govt profile. The end of the barrel is the part that has metal taken off. I dont see it being a problem on a semi. Heck M16A1s were pencils and they had automatic.
I think a pencil carbine barrel will be lighter, cuz there will be 2 more inches of pencil in front of the front sight tower
According to AR15barrels.com:
According to Bravo, the ltwt middy has:Quote:
Gov't barrels usually have a long taper from 0.675" to 0.625" under the handguards.
My digital caliper is dead at the moment, but eyeballing the hash marks on it, the ltwt middy I got on Monday does seem to be 0.575" forward of the FSB
According to this post, should be about 4 ounces
yea I noticed the govt taper too, thicker at the chamber end for obvious reasons and thinnest near the gas block. Are all pencil/lightweights suppose to be govt profile under the handguards? I would think so for durability purposes
You can also see from the second pic, some extra metal is removed near the handguard cap. Man my Delton feels like a pole compared to the lightweight
No, there are straight .625 barrels like this:

Which I believe is what DD is doing with their pencil bbls
saw a pic on G&R's website. Im assuming its one of there pencils. I could be wrong:

I can see a taper from the chamber end towards the gas block. Forward of the gas block definitely looks like a pencil. If this is a pencil picture, it doesnt look .625" all the way through.

Wow. They aren't kidding. :(
