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.
- However, military sniper systems come standard with single-stage triggers, so that’s debatable.
- Each BCG is MPI and HPT, but the real secret sauce is in the bolt.
- Aftermarket AR triggers also allow users to hone their rifles for specific tasks.
- With a 5-5.5 lb pull, you can’t go wrong with this trigger.
- One of the main reasons to buy an FRT trigger in Canada is the enhanced shooting experience it offers.
You might also have some anti-rotation or anti-walk trigger pins secured into place with small screws. If there is carbon or other debris in the trigger, you can generally clear it with some condensed air. With that in mind, it’s important to remove this carbon and fouling buildup at least every 500 rounds.

Private industry stepped up and offered many different triggers designed to fit the needs of today’s AR owners. Every aspect of a shooter’s experience starts with the trigger.

And stay in touch with newsletters of our best articles on techniques, guns, & gear.
Since the bolt carrier group is shot backward towards the shooter, the weight of it affects recoil. Even though most people don’t have automatic-capable rifles, they still prefer full-auto profile carriers. He owns over 200 guns in his personal collection, including over a dozen AR-15s, which he uses to test and judge AR parts, including bolt carrier groups. The ZF-5 is a semi-auto MP5-style firearm featuring a roller-delayed blowback operating system, a Picatinny rail, and a cold hammer-forged barrel.

Usually, it’s printed onto the bolt (either as MP or MPI), but this isn’t always the case. Semi-auto carriers are now the ugly stepchild of the BCG world and serve few purposes. While semi-auto versions used to be significantly cheaper than full-auto carriers, that is no longer the case.
At this point, the shooter will provide pressure on the trigger blade inside the trigger guard. A flat cut in this drum allows clearance for the trigger to travel once the shooter moves the selector switch to the “fire” position. We’ve already covered some of the mechanics when discussing types of AR triggers on the market.
An aftermarket trigger provides a cleaner, smoother trigger pull. With the sheer range of triggers available today, there’s not much reason to stick with a mil-spec. See, the beauty of aftermarket AR triggers is the insane number of choices out there. 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. Not only will this protect the metal, it’ll also facilitate a smooth, clean trigger pull. However, as with every part of a firearm, the performance and longevity of your trigger depends on how well you clean and maintain it.
Much of the time when AR owners discuss aftermarket triggers, they’re talking about “drop-in” units like the ones offered by RISE Armament. Depending on the design, upgraded standard triggers can have frt trigger finely finished, polished engagement surfaces or even entirely different engagement surfaces. There’s a separate trigger, hammer, and disconnector, and they’re all held in place by a trigger pin and hammer pin. These triggers could also be characterized as “non–drop-in” triggers.
