I was told by Gemtec that the 7.5 inch barrel does not always stabilize the bullets. They said to expect a can strike every 1000 rounds on average. They would not warranty the can for the damage of the unstabilized bullet.
If you want to run a can, I would suggest 10.5 to 11 inch barrel based on research. No first hand experience on my part. |

On something that short, you'll most likely want a heavy buffer. H2, H3, or even a 9mm if you listen to some of the talk around here. And as Mike said, most can manufacturers do NOT recommend using a supressor on any barrel shorter than 10.5". Even if you did, your not going to hush that bang. You might consider getting a longer barrel if you intend to use this for anything other than a range toy anyway.
That said...I love my 7"!!!

hmmmmm what about a 1:7 twist rate barrel? would that prevent a baffle strike with heavier ammo I wonder??

I run the ST-SST buffer from Spikes, on my 7 inch.. 5.56 loads were too hot and making the bolt run super fast. Their buffer is 7.0 oz and machined nicely.. I recommend it highly.

I think I'm gonna run that in my two builds. Both of mine are 11.5" though. I'm still researching to see if they are TOO heavy
