Take a gritty, inconsistent trigger out of the equation and focus on the other essentials of marksmanship — like sight picture, breath control, and follow-through. Even a basic, budget AR can see notable increases in downrange performance through a simple trigger swap. What are you going to get out of an aftermarket trigger anyway? All this talk about trigger types, mechanics, cleaning … is it really worth it?
Bootleg Adjustable Carrier – Best Adjustable BCG
That means each bolt is individually tested at a proof load. Mil-spec doesn’t mean the best or the worst; it’s just in spec for a military contract. But all it really means is that it is built to certain dimensional specifications so that it can work in military firearms. The main takeaway here is just get a full-auto weighted BCG if reliability is a concern. Full-auto profile means that the BCG is slightly longer and heavier, with an additional lug at its rear. Let’s clear the air first – “full-auto” BCGs are legal and don’t magically make your AR-15 automatic.
AR-22 Lightweight trip/weight carrier
Geissele collaborated directly with the metallurgists at Carpenter to create what they call a C158+ Stressproof bolt. Each BCG is MPI and HPT, but the real secret sauce is in the bolt. Much of the performance of those rifles can be attributed to their excellent Enhanced Reliability BCG (ERBCG). Geissele is known for its excellent rifles, especially the Super Duty line. He is an NRA-certified handgun instructor and a USCCA AR-15 defensive instructor. He has also researched and written over 250 articles on firearms and gear.
What started as a few guns turned into a bunch — almost 200 firearms. We also have a whole guide just on choosing a lightweight bolt carrier group, so be sure to check that out if you want to learn more. A lightweight BCG is designed for a tuned rifle and a builder who’s willing to toss an adjustable gas block on and really tune the gun. You can cut a few ounces off by using a low-mass bolt carrier. Low-mass or lightweight bolt carrier groups are relatively new to the market. Again, if it’s a duty or self-defense gun, I’d opt for something individually MPI and HPT.
Depending on use, trigger pull weight can vary in single-stage designs. As soon as the trigger-pull starts, the trigger sear is already pushing against the hammer sear on its way to the frt trigger break. These triggers have some of the most desired features a shooter may want. Many companies have found methods of providing modified trigger pulls by changing how the trigger interacts with the hammer or modifying the resistance offered by the hammer spring. However, as ARs have become more versatile in commercial and professional worlds, it’s important to have different kinds of triggers better suited to the tasks at hand.
- It might take a few tries to settle on a trigger you like best.
- These may feature finely tuned parts, lighter pull, shorter reset, cleaner break, and so forth.
- Finally, you might have some setscrews inside your trigger housing that push the trigger housing against the bottom of the receiver and exert pressure against the trigger and hammer pins.
- Every shooter has different preferences and different thoughts on what’s best for different shooting scenarios.
