Questions & Answers
Does this go with the gen3 15inch top rail piece? Expert Answer

The Precision Reflex Gen III AR-15/M16 Round Free Float Rifle Length Forearm is 12.5" in length and has an 8.5" top rail. So it will not work with a 15" top rail attachment.

by Hunter, Gear Expert, June 14, 2022
Can I use an armorers wrench for install? Expert Answer

Yes, the Precision Reflex Gen III AR-15/M16 Round Free Float Rifle Length Forearm can be installed using an armorers wrench. However, the manufacturer doesn't specify what size wrench is needed. I recommend contacting Precision Reflex for that information.

Helpful Positive Review Mk12ModH clone by j-dizzle, Verified Owner, April 7, 2021
PRI does not include instructions with anything they make. So you best have some skills before attempting to install their components. Installation requires a strap wrench or their custom wrench, which is just stupid that they make you buy it for $10...

If you're buying this handguard, you're buying it for a specific purpose most likely. The handguard is great and really solid. However, it doesn't come with the wrench to tighten the handguard down, so make sure you order that. Also, the barrel nut m...

Helpful Negative Review PRI forearm, Good quaility, but could use some qc/quality of life improvements by D, Verified Owner, October 24, 2024
The handguard itself, was pretty good. The cerakote was kind of all over the place in thickness, between 2 and 9 mils. and for $350, I feel like getting someone who can apply cerakote consistently should be something they can accomplish. For referenc...
