Rainier Industries Pro Series line of rails were designed for the hard use, professional end-user. To achieve this, we designed it an extended aluminum barrel nut and larger stainless steel mounting lugs for better rigidity to maintain a mechanical zero. The Pro Series MLOK rail is built to stand up to the rigors and demands of what your duty weapon requires.

Q: Will this 9.55” handguard with a can on a 10.25” Rainer match 300 BLK barrel? Is the flash hider flush or just past the end of the handguard?

A: Hi, you generally want atleast .625" of difference between the barrel length and rail length to account for the muzzle device overlapping the barrel threads.
