Armalite LTC 6.8SPC

I’m a big fan of the 6.8spc round. I have couple of carbines chambered in 6.8.spc.

I just bought an Armalite  LTC in 6.8 from Buds. The specs were pretty good. Armalte told me they didn’t build many of these.

1:11, Spec II, MPI and HPT, double hand lapped chrome lined bore, FF Keymod HG, Mil-spec Lower. I mounted a 4x TA31H-G GG&G BUIS, SSAE Trigger, CTR, CAA grip. Shooting some old SSA 115gr OTM’s it grouped 5rds sub moa. I paid $930 out the door so I’m pretty happy.

Last month saw XM68GD going for $7.99 a box at PSA. I guess LWRC building 6.8’s for the Jordanian’s has paid off in cheaper ammo. Is 6.8 being fielded by any of our guys?  

 

Original Post

I've been thinking a lot about the 6.8 myself, lately. My Dept has been nickel and diming a Tactical Team for a few years now. 12 guys or so. Now rumor is they are talking about starting a DM capability.

I was thinking a 12-14"  6.8 with a good LPVO would be just the thing. Bullets heavier than .223 would punch through glass better should the need arise in the DM role, and loaded with 90 gr GD, would be about perfect for entry type stuff.

I was thinking LMT because for high volume training they could switch  back to cheaper .223 and/or SIM / UTM. 

What am I missing?

Years ago,  after reading Dr Roberts results from Ballistics testing I had Tim Hicks ( Kotonics), build me 6.8spc Upper. It’s a sub moa Rifle and been 100% reliable using PRI mags. The Armalite is also sub moa , although not as accurate as the Kotonics.

I only had an MRP for a hot minute so can't confirm, but I'm willing to bet you're not going to have the same POA/POI when swapping barrels in an LMT (assuming you mean the MRP).   My AX is off about 1.2 Mils between my different barrels; can't imagine the LMT would be better. There are work-arounds but it's a pain in the ass, and you should always confirm.

Because of the administrative aspect, I can't swap out my AX barrels for competitions to 6.5CM for fear of not being able to re-confirm dope before work with the 308 barrel.  Suffice to say, switch-barrels don't really work for the litigious jungle that is LE.

 

I also thought the 6.8 might have a lot of real merit in LE, but the few times I looked at it, cost/logistics were a killer.

Thank you for your input. (Correct- MRP) I hear ya, What I had envisioned was the guys show up, switch out to a 5.56 barrel, load a UTM bolt, go about running scenarios until complete. They get the reps with their set ups, etc.  Most of their shots would be on the other side of a room. so I am not that uptight about accuracy/precision. If the training evolution involved higher volume live fire, sure, tweak their zero to accommodate the 5.56/.223 in order to get the best training value out of their time. (i know they are not the same, but I guess we buy whatever is cheapest). 

Once they are done, clean,reassemble, lube, and confirm/re-zero then back to the bricks. I do not intend upon relying completely on the 5.56 set up for all training, but I would have a better chance of selling it if I could show I'd be able to mitigate costs over the long haul.  A $.75-dollar a round platform for the type of shooting close work demands simply will not fly.  Additionally, as far as I am concerned, a system has to be able to allow for force on force training. That's why I haven't pitched the LWRCI already.

Thanks again

As far as my knowledge goes, no. At least not any mil guys. The hotness in SOCOM's R&D right now is the 6.5.

I guess I'm not the only one, then.  Tim also built mine before the company went under (sad story), and mine is a very accurate rifle.  The ballistics are hard to argue against and performance on deer here has been more than persuasive.  I reload for it but all of the hunting I've done with it has been with factory SSA rounds.  Fantastic cartridge.

Thanks,

For training, and to keep costs down, I have a Spikes ST-22, . It wasn’t cheap even years ago but well worth it.  The 6.8 calibrated ACOG is for the 115gr FMJ, but I haven’t adjusted it. I shoot mainly 110gr to 115gr no real noticeable shift in elevation.

Another 6.8 lover here.  Just recently there was a run of cheap Federal XM68GD which has a good reputation as a solid performer.  I've used the SSA 110gr TSX rounds and they've been absolute hammers on deer.  I have zero experience on shooting through barriers (unless you count the birch tree that jumped in between my and that buck last November).  I did hunt with a 4x ACOG on it for a while, but went to a 2-7x VX-R because my eyes suck and I wanted more mag for picking out critters in the woods.  I only had access to a 200yd range but the 5.56 BDC for me was good enough (minute of deer).  Or, get another Leupold and order custom turrets.

As far as the 6.5 Grendel, I'm sure others can speak to it's ballistics.  In my un-edu-macated opinion and from what I've read, up to 500yds or so the two are very similar.  16" barrel sounds like a sweet spot for the 6.8 while Grendel can go upwards of 1000yd but with 20+" barrels.  The 6.8 does seem to have a lot more bullets (or at least factory loads) than the 6.5.  How far you anticipate (realistically) needing to shoot could help steer your decision.

Lastly, I'm not a LE gun-toter but the idea of swapping barrels seems like a liability waiting to happen.  Swapping uppers may be a "safer" route if $$$ makes dedicated rifles a no-go.
