Description
Weighing in at roughly 0.2 ounces, the Strike Industries Low-Profile Forward Assist is one of those small upgrades that adds up when you're chasing a lighter AR-15. It keeps the same job a factory A2 button does, seating a bolt that hasn't quite gone into battery, but trims the weight by swapping the traditional steel body for an anodized aluminum plunger. For folks who count every ounce on a build, that kind of thing matters.
What Makes the Low-Profile Forward Assist Work
The smart part of the design is the material mix. The plunger body is lightweight aluminum for weight savings, while the pawl is machined from tool steel so it bites the forward assist ratchets on your bolt carrier the way it's supposed to. That combination gives you the mass reduction without giving up the positive engagement or long-term durability you'd expect from a part that sees repeated hard presses.
Fit and Finish on the SI Forward Assist
Strike Industries builds this in Santa Ana, California, and the fit and finish reputation holds up in real-world use. Builders report it dropping cleanly into Mil-Spec uppers like Aero M4E1 and similar receivers with no fuss. The black hard-coat anodizing adds corrosion resistance and gives it a clean satin look that either blends in or plays nicely against contrasting parts, depending on how you dress up your rifle.
Installing Your Strike Low-Profile Forward Assist
Installation is no different than a standard forward assist since it ships pre-assembled with the plunger, tool steel pawl, enhanced spring, and spring pin all in one package. Slide it into the receiver, drive the roll pin, and you're done. One thing worth mentioning: the textured button has a sharp, aggressive feel that gives you great purchase, so if you tend to really slam a forward assist, gloves aren't a bad idea. For a new build or a quick swap on an existing upper, it's an easy way to shave weight and add a little SI character.

Frequently Asked Questions
What does the Strike Industries Low-Profile Forward Assist fit?
It's designed for Mil-Spec AR-15 upper receivers and drops into most standard uppers without modification. Builders have had good luck fitting it to receivers like the Aero M4E1 and other common Mil-Spec designs. If your upper accepts a standard A2-style forward assist, this will work.
Does the aluminum plunger hurt reliability compared to a steel forward assist?
No. Only the plunger body is aluminum to save weight, while the pawl that actually grabs the bolt carrier ratchets is machined from tool steel. That means you still get positive engagement and a long service life, just with less mass.
Is the Low-Profile Forward Assist hard to install?
Not at all. It ships fully assembled with the plunger, pawl, spring, and roll pin, so installation is the same as any standard forward assist. Slide it into the receiver and drive the roll pin, and you're set.
How much weight does this forward assist actually save?
The whole assembly comes in at about 0.2 ounces, which is noticeably lighter than a traditional all-steel unit. On its own it's a small number, but it's the kind of part ounce-counters add up across a full lightweight build.
