thoughts on 6.8mm assault rifle, specifically lwrc m6a2 or barrett

[chad]

Been looking at some assault rifles and came across some stuff about the 6.8mm round, which is more powerful and larger then the 5.56. I was looking at getting one of these, and specifically looking at the LWRC M6A2. Any insight on the 6.8 over 5.56 for an AR, LWRC, or Barrett?
Thanks!

Thanks. Can't you use a 5.56 lower? You just need 6.8 upper and mags?

Yep. It will eventually end up with a new lower im sure. .

Have you looked at or do you know anything about Barretts Rec7 6.8 or LWRC's M6A2?

Can't go wrong with either of the above

Do you own or have you used either?

I have 2 6.8 rifles one piston operated i've shot the 3 mentioned. Out of the 3 I like the rec7 the best,and no I don't own any of the above mentioned but have friends that do and we shoot very often

Do you just want a Piston Gun or do you think you have to have one?

 

[chad]

Are you asking if I want one or if I need one? If so, I want one. I have an RRA AR-15, don't NEED it. Not practical for HD in my situation, nor hunting. Just a fun weapon to have, build, and shoot.

No I was specifically talking about a Piston Gun vs. a DI Gun. Personally I don't care for Pistons. I don't like the weight, cost, proprietary parts etc. I would rather have a DI gun. I don't think most people shoot enough to get the bennies of a Piston Gun. I really like the Barrett of the 2 you mentioned. But I would also recommend you take a look at the LMT MRP stuff. With the LMT system you can swap calibers easily.

Oh sorry, in that case... I really only know the basics of assault rifles. From what I know, I don't really prefer either over the other. I have only used DI and been happy with it. Not really sure what benefits if any there are with piston. I am just looking at the 6.8mm assault rifle, over the 5.56. I will look up the LMT MRP you mentioned. You can swap between 5.56 and 6.8? Thanks for the information!

I vote skip over the 6.8 and jump to .308 if a .223/5.56 is not adequate. More power, more range and more available ammo than the 6.8.

Just go to a 300 Blackout, should give you the punch that you are looking for in a small package without heaving to go to a bigger and heavier platform IMO.

OR as mentioned b4 .308 is easier to find than 6.5 and 6.8
