Description
There's a certain crowd that knows exactly why they want a teardrop forward assist, and this Luth-AR assembly is built for them. The elongated teardrop shape harks back to the original M16A1 style from 1969, giving your AR-15 that retro clone character while still doing the everyday job of nudging the bolt fully into battery when it needs a little help. It's a small part with a big personality on the receiver.
Why the Teardrop Shape Beats a Standard Round Button
The extended teardrop face gives you noticeably more surface area to push against, which is a real advantage if you've got larger hands or you're running an ambidextrous charging handle. The smooth profile skips the raised lip or rim you'll find on some assists, so there's nothing to catch a knuckle on when you're slapping it forward in a hurry. Plenty of folks with bigger builds like the 6.5 Creedmoor and 6.5 crowd track these down specifically for that reason.
What Comes in the Luth-AR Forward Assist Kit
This is a complete assembly, not just the button. You get the teardrop forward assist, the assist spring, and the assist pin, so whether you're finishing a fresh build or swapping out a worn-out unit, you've got the full set of parts to get it done. It's machined from mil-spec materials and made in the USA, and it fits standard forged AR-15 upper receivers.
Installing the UR-08-T on Your Build
Installation is straightforward for anyone comfortable working on their own upper, though a punch set makes seating the roll pin a whole lot easier. Once it's in, it functions exactly like any standard forward assist, just with that added surface area and old-school profile. For A1 clone builders and retro fans, it's one of those details that pulls the whole rifle together, and for everyone else it's simply a solid, well-made replacement part that works.

Frequently Asked Questions
Will the Luth-AR teardrop forward assist fit my AR-15 upper?
It's built to fit standard forged mil-spec AR-15 upper receivers, which covers the vast majority of uppers out there. If your receiver is machined to the common mil-spec forward assist dimensions, this drops right in. It's a good idea to confirm your upper is a standard forged type rather than a specialty or proprietary billet design.
What's the difference between the teardrop assist and a regular round forward assist?
The teardrop version has an elongated, larger face that gives you more surface area to push on, while the standard type uses a smaller round button. Many builders prefer the teardrop for its M16A1 retro look and because there's no lip to catch a knuckle when running ambidextrous charging handles. Function-wise, they do the same job of seating the bolt into battery.
Do I need special tools to install this forward assist assembly?
A punch or roll pin punch set makes the job much easier, since you'll need to drive out and reseat the retaining pin. Beyond that, basic AR gunsmithing familiarity is all it takes. It's a manageable project for most home builders working on their own upper.
Is everything included to install the UR-08-T, or do I need extra parts?
The kit is complete and includes the teardrop forward assist, the assist spring, and the assist pin. That means you have the full set of components needed for a fresh build or a straight replacement. You won't need to source any additional small parts to get it running.
