Timney AR15 Competition Trigger | Straight | Large Pin | 4lb

The Timney AR15 Competition Trigger in the straight shoe, large pin, 4 pound configuration upgrades your rifle in the time it takes to drink a cup of coffee. It arrives fully assembled as a self contained drop-in module, so there is no fitting, no adjusting, and no gunsmithing between you and a dramatically better trigger press. Shooters compare the result to a quality bolt action break for good reason.

Why Shooters Pick the Timney AR15 Competition at 4 Pounds

The 4 pound pull is the versatile middle ground of the lineup, light enough to reward good technique but substantial enough for defensive drills and field use. If a 3 pound match trigger feels too delicate for your purposes, this weight keeps the crispness while adding a margin of deliberateness.

This configuration fits AR-15 lowers that use Colt style large pins, giving owners of those receivers a genuine premium option. The flat, straight shoe rounds out the package for shooters who have learned how much consistent finger placement matters.

Within the broader Timney AR15 Competition family, the 4 pound option is the one most owners end up recommending to friends. It flatters careful shooting without punishing hurried shooting, which is the balance most real world rifles actually need. It is equally at home on a match gun and a do everything carbine.

Feature Highlights

These are the details that justify the upgrade:

• Single stage design that breaks clean at a consistent 4 pounds with no creep and minimal takeup
• Flat, straight trigger shoe with a broad contact surface for repeatable trigger control
• Fully assembled drop-in unit with every component housed in one aluminum cassette
• No fitting, adjusting, or gunsmithing required at any point in the installation
• Purpose built for AR-15 lowers running Colt style large pins

Specifications Worth Knowing

Pull weight is a consistent 4 pounds, shot after shot, because the sear engagement is set at the factory rather than left to an installer’s judgment. The single stage action means one smooth press from touch to break, with none of the gritty stacking that plagues rack grade fire control groups.

The aluminum construction keeps the module light while holding the internals in permanent alignment. Combine that with the straight shoe geometry and you get a press that feels identical whether it is round one of practice or the last stage of a long match. That consistency is the entire Timney value proposition.

Factory set sear engagement also removes the most common failure point of adjustable triggers: well meaning owners tuning them out of spec at the kitchen table. There is nothing to tweak here, which means there is nothing to get wrong. Set it, pin it, forget it.

Installation, Compatibility, and Care

Confirm your lower uses Colt style large pins, then set aside a few minutes: pull the old parts, seat the cassette, and pin it in place with your rifle’s existing hardware. First time upgraders routinely finish the job with nothing more than a punch set.

Maintenance is minimal since the sealed cassette keeps carbon and debris away from the sear surfaces. When you are ready to match the rest of the lower to this trigger, our parts and upgrades aisle covers grips, selectors, and springs to finish the transformation.

Expect your groups to tell the story quickly. Shooters routinely discover that flyers they blamed on ammunition or barrels were actually trigger press errors the old fire control group was hiding. A clean 4 pound break has a way of making honest shooters out of all of us.

If your factory trigger group feels heavy or gritty, the Timney AR15 Competition Trigger at 4 pounds is the straightforward cure that sharpens accuracy without babying. Press it once and the old trigger becomes a memory. Ships direct to your door, no FFL required.
