Hello, I'm a new member

Hello all,

I'm new to the forum and new to the caliber. I have a 10.5" 300Whisper upper for my AR in the works...and I'm hoping to finish it sometime soon. My biggest concern is the cycling with subsonic loads...and of course, accuracy. I have a big ass .30cal suppressor for it already and if everything goes as planned I'm soon the happiest shooter at the range. :D

Regards,
Kanttori

We are all wrestling with the subsonic cycling problems. This board isn't as active as AR15.com, but we do eventually respond :lol:

The suppressor should help with the cycling. Who's doing the 10.5 for you?

I would suggest using the pistol location for the gas port on the 10.5. You can always add a pig tail tube or AGT(adjustable gas tube), but if you don't have enough pressure you will be like the rest of us with Model 1 uppers trying to squeeze alittle extra out of our gas system to cycle.

Has anyone discussed with model 1 the thought they should use the pistol location instead of CAR location on the barrel?

And Yes I'm a new guy - and I haven't ordered all the parts yet (have a lower ready to go)
