Red x arms?

Haha, no sweat dude. Yeah I never found exactly what I wanted. Samson makes a rail that will probably work, but I need the barrel and can together before I can tell what will work. The MOE guard works for now.

I'm kind of hoping you still consider the Samson rail. Their Evo Series look great. I'm really considering one for my 300 build. My plan is to keep it a DI system for simplicity. I'm still unsure whether or not I need an adjustable gas block though. I do plan to shoot suppressed and unsuppressed. Anyhow, I think I've done a good job of derailing Muley's thread (sorry dude), so I'll save it for another day when the time comes to ask the questions.

Damn...... I may have to pull the trigger on one of these uppers too!

I'm feeling really tempted to make a purchase and sell my 3 month old upper

My bad dude. I just remember a post you made trying to get a two piece hand guard to work with your adjustable gas block. I think you had gave up on it and was trying something else, but for the time being the MOE would suffice till you found the guard you wanted, or one that worked for your needs.

I try not to buy shit I don't need. I don't need a quad rail, the only accessory I will use it an IR illuminator for NV, and my MOE has a rail for that. The only thing that will make me switch is if I can't make a custom hand guard cap to accommodate a suppressor.

I know what you mean. It's not want you want, but it's what you need to at least get it out to the range.

Right now I'm going to try to use a midlength MOE handguard as a placeholder.

Also CJ, what hand guard did you settle on, and are you still extending the HG out over part of the suppressor?

That's really funny because I found the same barrel and ordered it already. I did some homework on the 10:1 twist barrel and it just won't work for my application. But if you don't intend on shooting subsonic its a great deal.

Hell yeah dude. I know you're chompin' at the bits to finish your build. I figured since I'm in a holding pattern waiting on the suppressor and sbr stamps, I'll keep with the Reaper Tac barrel. GRT has a back order of around 4 to 5 weeks to ship, so im in no hurry. They had already debited my account May 21 so I figured I could give them till the latter part of June on into the first week of July before I called or Emailed.

I was planning on getting it to be suppressed eventually. So when they get back to you the info relayed would be great. What twist rate would you be looking for?

It's hard to say what a 1:10 twist will stabilize up to. It may stabilize 220gr, it may not. I would say a 1:10 is probably good up to a 180gr without any doubt. I went with a 1:8 which should be good to a 240gr. The slower you move the bullet the heavier you want, so you can transfer from velocity to weight and still get the same energy delivery.

ex:

150gr @ 1600fps = 850ft/lbs.
240gr @ 1130fps = 860ft/lbs.

You always want the least twist if at all possible for barrel wear, longer the barrel the less twist is necessary. A 1:8 or 1:9 should be okay, a 1:10 is questionable, it may work, it may not.

Found another 300blk barrel for a good price, shows to be in stock also. Only downside is the 9.5 length.

I asked them if they knew if it would stabilize, they have not gotten back to me yet. From what I can find, it seems iffy if it will or won't. For 95% of the guys on here it would be perfectly fine, but if you plan on using your gun with a .30 cal can this could be bad news. So, if it doesn't work for me I will sell it.

Have you called or emailed to ask if they have already done some ballistics for you?
