Boarman03 Report post Posted February 13, 2023 I'm sure he has a specific intent and wants to maximize his powder burn and velocity, accuracy. 1 Share this post Link to post Share on other sites
49ford8n Report post Posted February 13, 2023 Thank you Boarman03. I have a tendency to think different about calibers instead of following along. I have had good results with distance and accuracy using a 16 inch barrel with carbine gas. I would like to try a rifle setup. I believe it could be a great 30 cal varmint setup.

bowhunter-tw Report post Posted February 13, 2023 Would you be shooting subs out of that set up? Id be curious how the build comes out Its a 16” not a 20” but decent sale going on https://www.ballisticadvantage.com/16-300-blackout-pistol-length-ar-15-barrel-modern-series.html 20 may be hard to find since it is against the norm Share this post Link to post Share on other sites
