The oal is 3.25in. Its about .725 from the back to where the crown would bottom out. So I would guess that it would add about 2.525 to the end of the barrel. I've got a 5.56 also if anyone needs a measurement I've got two 7.62's ecr's coming anyday now. Zero is going to break me.

They showed the clamp that holds the rails steady. I wasn't sure if the loctite was necessary, or if you could get by without it.

Finally got my SBR papers and want to put her together. When I screw the rail on it doesnt quite line up, so I backed it up one turn. Is there suppose to be a gap between the rail and upper? I don't think I should force it that last little bit. When I tighten the barrel nut, how do you keep the rail...

Can we buy the long barrel if we already have the short one? I wouldn't mind both.

Sarah has been lusting over me since she found out I got this gun.

put me on the list also

how about a 300 blackout barrel? Does kac make an e3 blackout barrel?

Would it be possible to get the barrel with dimples?

I wouldn't mind the sbr. The only downfall is the engraving. I would rather have a sbr papered from kac if possible. But I'm up for what ever works.

I've got all my parts in the safe just waiting for a KAC dimpled barrel and bolt/carrier. Hopefully xmas will be good this year.

Put me down for one also. Thanks

Put me on the list for one.

I am an original owner. James Starr in Ne. Merry Xmas to the KAC family.

You need to add me to the list as an original buyer. Casey has all my info. Thanks James Starr in Ne

count me in for 2 of them

Just checking to see if theres any app that will be available for the Android. I'm stuck in a contract with viaero and they have the samsung android.

I still have the upper and lower and am wanting more KAC parts to finish it. Has the list started for the handguard?

MDM gets my vote.

I wish we could get a dimpled barrel and a bolt. I would like to build the gun with all KAC parts.

Count me in for accessories for my upper and lower. Handguards would be a nice touch. I just would like to keep the parts KAC. Didn't Johnny Cash have a song about a car, one part at a time.

I would like one with dimples and gas block. Also I have a question for anyone. When you SBR'd your lower, where did you mark it, and who did it. I assuming that you can't refinish it without ruining the KAC on the side? If so, how does that work when you engrave your name on the lower? Thanks for a...

My wife is going to be happy when I quit hanging the lower on the tree.

I'll get an email in as soon as I get back from vacation. J starr with virgin receiver via blackberry.

My lower is just sitting here waiting for the right upper. Thanks Trey!

I've still got a receipt for a SR50 in the safe, but I'd be up for a PDW also.
