15deg grip works great and serves well - Strike Industries AR-15/AR-10 Enhanced Pistol Grip

Picked up this 15Deg grip for an AR for longer reach. Coupled it with a fixed stock with a bit longer length of pull and am very happy with the results. The more vertical grip angle works well in a precision shooting scenario from seated, kneeling, and prone positions in my configuration, compared to the standard grip angle I have used. The grip is durable, and seems to be pretty consistent regardless of temperature. It's a different feel than the more common Magpul grip texture, but it offers good purchase for my hands and in fact may be slightly more abrasive on the front- and backstraps of the grip than the Magpul, for longer periods of use. Due to the abrasive quality, my gut level, unmeasured assessment is that in sweaty conditions there may be a bit of extra grip with this texture than the Magpul, though that's no more than a "maybe this is the case" kind of assessment. I will say for extended shooting sessions, I may convert to a gloved hand configuration based on the more abrasive front- and backstrap texture.

Not sure what the guys complaining about it being flimsy or low quality are seeing, but mine has been run through the gauntlet in wringing out the new rifle platform. I've run it at the bench, prone, and in mobile/multiple shooting position drills in real-world conditions. No quality issues have been seen.

I will say I like the rubber plug in the bottom better than the plastic plug for my Magpul grips. It is easier to remove/install. It does not offer the various storage options like the Magpul inserts, but I've never used those, anyway, preferring to simply wrap items in thin foam and store them in my grip. Seems to work and is quiet. Since I use these AR platforms for both personal defense and hunting scenarios, quiet is good.
