300BlkTalk

Sorry if I'm alittle slow and I don't mean to anger anybody but can somebody explain the lies and half-truths to me? Keep in mind that I'm also behind enemy lines and can't legally have a suppressor. I also don't have a 300BLK but I have friends that do and the round does intrigue me. I understand t...

My last 2 223/5.56 barrels have been from AR 15 Performance. Melonite treated, 1 in 8 twist Hybrid 5R rifling, mid-length gas system, 5/8x24 thread (1/2x28 could also be purchased), reasonable priced, and shoots lights out (for me). Keeps up with my WOA and Shilen for half the price. YMMV

Are you using factory or reloaded cartridges?

I'd say drill & tap a sling stud into the handguard. Replacing the gas block with a picatiny rail defeats the whole purpose of a free-floating barrel.

Just my 0.02.

Mr Silver already have your answer...since he designed these things...I would go with his advice. Thank you so much for your insightful and detailed response. I totally understand how a heavier buffer would correct a short stroke problem. Let me see... I have stated that AAC 9 and 12.5 inch barrels...

Curious. I don't understand how a heavier buffer would help it to cycle better. I would think that a heavier buffer would compound the problem. :shrug:
