ERGO built the TDX-0 for anyone who has ever felt like a standard angled pistol grip fought their wrist behind a scoped rifle. This is a straight zero-degree grip, meaning it stands vertical instead of raking back, which puts your hand into a more neutral posture and lines your trigger finger up cleanly. It started life as the grip for the Ruger Precision Rifle and has since found a home on AR platforms, chassis guns, and just about anything that takes an AR-style grip.
The zero angle really shines on precision and prone setups. Getting behind a chassis rifle or an SPR-style build, the vertical geometry lets you tuck your elbow, relax your wrist, and press a flat trigger straight to the rear without cranking your hand into an awkward spot. Folks who have wrist issues from years of hard use tend to notice the difference right away, and it pays off during long strings where fatigue usually creeps in.
The outer shell is ERGO's overmolded SureGrip rubber with their heavy texture, so it holds up in rain, cold, and sweaty summer range days without turning slick. The integrated beavertail fills the web of your hand and rides up against the receiver for a repeatable, high hold, and the ambidextrous palm swells work whether you shoot right or left handed. Worth knowing up front: this is a full, hand-filling grip, so if you like a thin profile it runs on the chunkier side.
This is the 4021 beavertail version, fitting AR-15, AR-10, M4/M16 lowers, and bolt-action chassis systems that accept AR-style grips. It installs with the included hardware, and a 3/16 wrench makes the job easy. Everything is made in the USA and backed by ERGO's lifetime guarantee, so it is built to stay on the rifle for the long haul.
A zero-angle grip stands vertical instead of raking back like a standard AR grip. This puts your wrist in a more neutral, natural position and lines your trigger finger up straight to the rear, which is a big help on precision and prone setups. Plenty of shooters with wrist strain find it far more comfortable during long sessions.
No, the bottom grip plug is sold separately for this model. The grip does include the installation hardware you need to mount it, including the bolt, star washer, and the Gapper. If you want to seal off the cavity at the base, you can add the matching TDX-0 plug.
Yes, it fits AR-15, AR-10, and M4/M16 lowers, along with bolt-action chassis systems that accept AR-style grips. It was originally designed around the Ruger Precision Rifle before coming to the AR family. If your rifle takes a standard AR grip, this one will bolt right on.
This is a fuller, hand-filling grip with a beavertail and palm swells, so it runs on the thicker side rather than a slim profile. Most people love how it packs the palm and supports the hand for a repeatable hold. If you prefer a very thin grip, keep that in mind before ordering.
