12.5 SBR build - txgunner00 - 05-20-2014
I've been planning this for quite some time and it's finally coming together.
Specs
Upper-
Sabre Defence 14.5" barrel cut to 12.5" and threaded to 5/8"x24
BCM blem receiver
AA hard use bolt (unsure of carrier manuf.)
BCM MKR10 handguard- REALLY liking this one- super light and great profile. Seriously considering switching everything to it.
Micromoa Govnah switchable gas block
YHM QD break for the Ti 7.62 can I have in ATF jail.
MI keymod grip panels
PRI Gasbuster charging handle
Optic-
1-4 VX-R ballistic firedot in Larue mount- Still undecided if this is going to stay or go to a 2-7.
Lower-
RRA SBR'd receiver
RRA NM 2 stage trigger
Magpul CTR stock
Hogue ghillie tan grip
BAD lever
Base coat of Duracoat Tactical Dark Earth. Camo pattern will be done soon.
Mockup before cut down
Lathe setup- I'm NOT a gunsmith or machinist. I know just enough to make chips and get myself in trouble sometimes.
2" removed

This is how she sits now. I hope to be able to finish her this week and get to the range this weekend.
Constructive criticism is welcome!
12.5 SBR build - Whelenon - 05-20-2014
Great photo journal of a job well done. Would love to see a short video of you shooting it with the can on. That's going to be sweet.
12.5 SBR build - txgunner00 - 05-20-2014
Thanks. It will be a couple months before I get my can but I may have an opportunity to test it with a buddy's can before then.
12.5 SBR build - BluntForceTrauma - 05-20-2014
Love it! 12.5" is my perfect length and I want one in 65G BAD!

That's cool. I'm thinking about doing a similar build using the same barrel. Do you happen to know the empty weight of the complete rifle?
12.5 SBR build - montana - 05-20-2014
"Constructive criticism is welcome", well here it is : That rifle would look much better with me holding it.
That turned out awesome, That will be a sweet, light weight, fast handling shooter. Job well done. Looking forward to seeing the finished camo job. Thanks for posting.

Looking good so far. Can't wait to hear your range results!
12.5 SBR build - Klem - 05-21-2014
Nice one.
Is the spindle-bore of that lathe not wide enough to fit that barrel? What I mean is (and you probably know this) the closer you can get the work area to the jaws of the chuck the less run-out there is.
12.5 SBR build - Kohoki - 05-21-2014
Nice!
12.5 SBR build - txgunner00 - 05-21-2014
Camo job done (for now).
12.5 SBR build - txgunner00 - 05-21-2014
Thanks for the compliments everyone.

7.4 lb. With suppressor, sling and 10 round mag I should be under 9 lbs. I can't wait to do some stalking with it.

The spindle bore is 1" and the barrel extension is just a hair over. When I bought this lathe (second hand) I was hoping the bore would be slightly larger than it's stated diameter. No such luck. At least I got a good deal on it but I have my eyes out for a larger one.
12.5 SBR build - LRRPF52 - 05-21-2014
Dude, that is sick! How did I miss this? I guess I've been out of the loop, jumping through fiery hoops.
That's a nice little hunting stick right there if I ever saw one. Should balance really well.
Looking forward to your range results, as you should be somewhere around 2300fps with 123gr, and 2500fps with 100gr pills.
12.5 SBR build - Kohoki - 05-21-2014
OMG, someone opened a bucket of awesomeness and poured it all over that rifle!
12.5 SBR build - txgunner00 - 05-21-2014
LOL.
Balance is nearly perfect for me. This rifle is will on it's way to being my new favorite.
12.5 SBR build - txgunner00 - 07-04-2014
WOOOHOOOO!!!!!
My can finally was released from jail! YHM Ti 7.62
8.7 LBS as it sits in the picture. 9.7 with 25 rounds in the mag. This is about as perfect as you can get for a walking rifle IMO.

Just need to paint the can and the light now.
Hopefully I find some hogs next weekend.

That's nasty!

Awesome TXGunner!!! It looks great, and you are going to have major fun with it!
12.5 SBR build - txgunner00 - 07-05-2014
Thanks man. Have you played with those subsonic bullets yet? I shot some of my loads for the 20" in this one the other night and they are right on the edge of working 100%. All the cases ejected but only about 1/2 of the shots picked up the next round. I think I might have some room to bump up the charge since this barrel is shorter. I also have a Micro MOA gas block on it with several plates I can tweak the gas port on.
