Sig quality - SIG SAUER Elite Match Grade .300 AAC Blackout 220 grain Open Tip Match Brass Cased Centerfire Rifle Ammunition

This is consitentent Subsonic ammo. I have not experienced any sonic rounds in the batch, and it cycles very reliably. For Close to med range applications it is extremely accurate and consistant since your barrel stays below hot. I like plinking with the Stelth ammo. This is my go to mag filler. I wish it was cheaper it is just so much fun to shoot. So Far I reccomend Magpul Gen 2 mags for feed reliability. I tested 3 other brands and 1 other Magpul gen. If using an AR platform you may want an adjustable or suppressor friendly spring and buffer.
