300BLK Piston Upper with Aero Precision M-Lok Rail

Q: Good afternoon i am looking at the 10” 300BLK low profile piston upper with the AP 12” m-lok rail system. So my question, i have a rugged radiant 762 and need to know if the suppressor will fit inside of the rail system.

Asked by: Taylor Frisby - 8/28/2023

A: Yes your suppressor fits with the handguard with plenty of clearance.

Q: What buffer spring and weight do I need for this 300blk? Can a JP Enterprise silent capture spring be used?

Asked by: Anthony Kessler - 2/22/2023

A: H2 buffer and standard carbine spring. You can use a JP Capture Spring if you modify the carrier's polymer buffer to open it up a little to allow the rod from JP to clear it.

Q: I'm interested in this upper 10" 300BLK Complete Low Profile Piston Upper with A.P. 12" M-Lok Handguard. My question is, with the suppressor mounted within the hand guard can you still get to the locking collar to turn it to the locked position? Regards

Asked by: Mike - 11/25/2022

A: If you already have a suppressor that utilizes a locking collar we recommend going with the 9" handguard. If you don't have a suppressor and you have to get one there are suppressors that require a locking mechanism you would need to get to and then you can use the longer barrel.

Q: What is the inside diameter of the rail? Is it suppressor friendly?

Asked by: Marine66 - 2/10/2019

A: The handguard is 1.72" inside diameter and fits most 1.5" suppressors. Our 300Blk 10" and 16" piston uppers are suppressor friendly, you can shoot subsonic ammunition with or without a suppressor.
