POTD: The Holt Works Photography 7.5” Shorty 5.56 SBR Build

Another amazing build and set of photos from Holt Works Photography, to go with our Photo Of The Day. For short barrels, I’ve personally gone with calibers like 9x19mm and 300 Blackout, and not the 5.56. According to Holt Works, the Infinity 7.62 Suppressor is up for the job.

Here’s the caption:

“I’m not a fan of 5.56 in barrels shorter than 10.3”… unless it has an @ottercreeklabs Infinity suppressor on it!

This can is wild! 3D printed inconel with vented or solid end caps. With the vented end caps there is zero gas to the shooter on any setup that I tested. The solid end cap is also low gas and sounds phenomenal.

Can’t wait to try it on some larger calibers soon.”
