SBR 458 SOCOM begins!

[gunselman]

I am finally getting my stuff inline on my 458 SOCOM SBR build. I had A Rock River 16" 458 SOCOM and decided that i wanted something a little different. With the 458 SOCOM dropping from 16 to 10.5" doesn't really lose me much velocity at all.

Rifle Specs:
Barrel: Southern Ballistics Research, LLC (SBR) 10.5" Stainless steel, threaded
Receiver: Rock River Arms lower
Lower Parts Kit: Rock River Arms
Stock: Magpul UBR stock, green
Grip: Ergo
Forearm: aluminum free float, to change
Muzzle Device: TBD
Sights/Optics: TBD

This is going to be the first item put through on my NFA trust.

• Paperwork sent 7.16.2013
• Check cashed 7.23.2013
• Pending 9.11.2013
• Stamp received ?????

I will post some pictures of this built up as a pistol soon.

Can't wait!

Sweet! Sounds like a very nice build! I hope to have my stamp back in a month or so, I'm going 10.5" too

 

[Aszerigan]

I see no suppressor listed. Shame, shame.

 

[gunselman]

I see no suppressor listed. Shame, shame.

Maybe later.. I don't have the money for that right now.

 

[gunselman]

Talked to ATF. I went pending on 9.11.2013!!!!

Aszerigan, I did see your supressed 458 socom in person yesterday at your store. It was surprisingly lightweight!

Lol...Only 6 more months!

Lol...Only 6 more months!

Haha. Funny joke. Try 9 months buddy.

Small updates:
1. Upper receiver is back from Paladin Machine. They opened up the ejection port to properly eject the giant 458 SOCOM shells and retain the cover!
2. Lower receiver is back from LaserScribe. They did the engraving on the lower to comply with NFA regulations.

How'd I miss this thread? I love my .458 and am very tempted by the Bowers suppressor. Tagged!

 

[gunselman]

Engraving done very nicely by LaserScribe.

Starting to become impatient with the ATF. Went pending on 9.11.2013, next Friday will be 6 months after pending. I just called them and they said that it can take up to 10 months after it goes pending!

My last SBR took 12 months total. I believe it took about 9 months after it went pending for mine. Received it last january.

Hence my post earlier in this thread from October. I don't know who told you 6 months. I just got my stamp back today for my form 4. Its been almost exactly 10 months.

 

[gunselman]

Look what came in!

 

[DaKruiser]

Look what came in!

Woohoo! Congrats!

Its been 20min. is it together yet?

 

[gunselman]

It's not together yet. I had to modify the gas block a bit to fit under the hand guard. I am having a hard time finding a muzzle brake i like. My barrel has 5/8-32 threads which isn't very common. I looked at the RRA 458 brakes this weekend at the NRA convention and am not all that impressed. Anyone know of any others threaded for 5/8-32?

 

[protias]

Any of these work for you?

[DaKruiser]

I believe Tromix plans to make these, might be worth emailing them if you're interested in it. Tony, the owner, is one of the original guys involved in developing the 458socom,
