Spectre Ballistics Light Practical Carbine - NR Receiver Set

[STEELCITYSLICKER]

I just got nervous about having a Ballistic Advantage barrel........

 

[SpectreBallistics]

ugggghhhh...that's a tad disconcerting; I picked up a 16" MRA wylde barrel specifically for this. I do, however, plan on using heavier pills, handloaded.

Is the tested MRA barrel a 1-8" twist?

Absolute worse case is the LPC gets my 224 Valkyrie barrel and bolt, I guess, but it would definitely **not** be light, practical, or a carbine in that configuration.

Your barrel will probably be fine. The barrel we used is quite old, and I believe they switched to a different blank now. Also, we never tested anything heavier than 62 grain with it.

This is reassuring, thanks!!

Getting stoked for this, hope your admin issues get resolved in a timely manner!

Is extracting window large enough to support .450 bushmaster. Want to build big bore shorty.

I have a 18.6 MRA barrel 223 wylde 1:8 with 68gr hand loads it's consistently under 1 moa.

Do you guys have an estimated ETA (relative to when the first 1-2 batches are ready and out the door) of when you'll have spare uppers available for sale? Just noticed that you have them up on your website.

How does this thing stay locked?

With locking lugs, like a Ross rifle or K31.

Hi, I can't find on your website what the overall length of the receiver set is? To determine how long/short a barrel can be put on here and still meet the Non-res length?

I don't know of course, but you should probably be fine if they are only having problems with Barnaul (Steel case) and Independence (Really Effing Hot)

Regular pressure 223 brass case ammo is less likely to cause problems than steel case or high pressure 5.56 in my experience.

I've got a pile of hornady steel match ammo I was planning on shooting. Hopefully It'll be fine with my faxon pencil barrel.

I took the spring out of my ar and when I tilted it up the action slid open. Does that happen with this setup??

It wasn't so much the issues with Barnaul or Independence that gave me pause, it was the "3MOA at best" comment but, as SBI stated above, it's an older barrel, light and/or steel cased bullets, etc, etc, so I'm optimistic about my chances with working up decent 62/65/68/69gr loads for it.

I asked this same question early on. SBI answered that with a mag in, the carrier is held forward by the locking lugs and upward force applied by the mag spring and follower to the carrier. SBI further stated that they tested this a number of ways and found no problems. That said, I do not recommend this firearm for use in an anti aircraft role.

With a magazine inserted, no.

Here's a pic of the rifle sitting vertically.

Can you put a Ambi AR safety on it?

Yep, absolutely. The reason you don't see it on our rifles is I absolutely do not like them. Personal preference.

Awesome! Thanks for thinking of us Southpaws.

Also as to my previous question, what's the overall length of the receiver set? To look at a minimum barrel length with a fixed stock.

It's going to depend on your stock. With a Magpul MOE, minimum barrel length is gonna be 12". With a fixed stock you can go shorter.
