Thread: 300BLK on AR Platform for Bush Hunting

I have a 6.8SPC that im using as a bush gun. I had the barrel profile taken down and a carbon handguard fitted, its just over 6lbs with scope.

Running 110vmax at the moment which kills ok on deer. Thinking about 85ttsx so im a bit more comfortable planting a shot in the centre of a big shoulder.

I like it

So it's a slightly bigger projectile, but still designed for longer range accuracy like the .223? Its more of a speciality calibre in the AR though isn't it?

Would the 300blk not be more appealing as a AR owner because all that's needed to go from 223 to 300blk is a barrel swap? Whereas the 6.8 would require different bolts and mags?

I like the idea of subsonic 300blk for goat and wallaby culling, which isn't possible with 223/6.8.

Yep with the 6.8 you need a different bolt and mags. I just have a 223 upper as well with a dedicated bolt, to be honest most people that I have seen with multiple uppers have a different bolt carrier for each one, it kust makes switching them out even more easy.

I can push a 110vmax to about 2650 in a 16" barrel while the black out pushes them at 2250ish I believe.

Sub sonic is a bit of novelty from my experience, I have killed a number of goats with subs in the 308 and its pretty average in terms of killing ability.

Thats impressive, often when people talk about a 'lightweight' AR it turns out its still 8lbs!

buy a cheap 2nd hand 308 or 7mm08 , plenty out there, and chop down the barrel to 18in. Much better, lighter option for bush bashin and lower costs to run imo. And much more effective in terms of knock down power.

Been there done that. Just sold a 7-08 bush pig I built. Looking at something different, that's all. And always wanted an AR so trying to justify it
