AR Drop In Triggers?

[owen67]

I’ve used CMC and AIM Surplus “cartridge” type assemblies. Don’t know who designed or makes AIMS but they ARE quality and priced well. Another AR I have I used an Obsidian Nickel Teflon coated assembly that came with the sear polished etc. I used WOLFE lighter trigger springs, but the WOLFE one step heavier hammer spring. Drilled and threaded the grip mount I g screw hole clean thru I to interior of receiver and installed a dog head set screw with red Loctite to remove all slack and take up.Did this one perhaps 8-10 years ago, and I get compliments all the time on it . Breaks about 3.5lbs very consistent, no creep etc. my Dad shot mine after shooting his stock AR trigger, proclaimed his garbage, and ordered an AIM cartridge type (at 80 he didn’t feel confident doing the other work and couldn’t find the nickel Teflon ones). At that time I think it cost me $70 with the Wolfe springs.

I like 2 stage triggers. Line up the sights, take up the first stage pull, then do a final sight line up and squeeze the crisp short last stage. With the 2 stage trigger you know when the rifle is about to fire. Since the second stage is crisp and light, it feels like a very light trigger, yet is totally safe because of the first stage.

I give another vote for the LaRue Tactical MBT-2S Trigger. For the money, it is the best trigger that I have found....

Thank you everyone. I decided upon a LaRue Tactical MBT-2S Straight Bow Trigger. I'm somewhat familiar with the installation & how it operates.

I believe that LaRue has an installation video on their web site that guides you through installation. Not hard at all. Helps to use a punch as a guide to align things as you install it...

Out of what I've used I like the Hyperfire products best... That said I really like the idea of the self contained triggers. Something to be said about not being at the mercy of poorly positioned holes in the lower.

The pin holes still have to align with the holes in the trigger module. Not of my modular trigger have sloppy or oversized holes in them.  I'm not hearing what you are saying.

Perfect alignment matters. The internals of a well built modular trigger should hold tolerances well beyond what is seen in Mil spec receiver pins.

Nothing wrong with a drop-in trigger. John Garand designed the M1 with a modular trigger/hammmer group----the TRIGGER GUARD ASSEMBLY. The trigger guard doubles as a spring latch to fasten receiver in stock. The Garand is an “open” trigger. Mike Walker designed the Remington Model 700 with a “box trigger.” Containment intrinsic in a box trigger houses parts of low inertia, adapting to fine, single-stage tuning. While the box protects against dirt intrusion, once dirt gets inside reliability goes downhill. Same applies to water when it turns to ice.

Eugene Stoner’s AR 15/M-16 was thrown into the fire before reaching full maturity. Worse, the rifle was promoted (within the military-industrial complex) as needing little or no maintenance. This may have been a swipe at Avtomat Kalashnikov 1947, which Mikhail Kalashnikov designed specifically to ne manufactured on rough machinery with low-tech steel, and to function when issued to minimally educated persons with minimal training, with little or no cleaning gear. For Kalashnikov, a box trigger would have been unthinkable. It is a testament to Stoner’s brilliance that his design spans generations without obsolescence, that it’s a natural for optics, and it can be tricked out, and works with open or box trigger.

I’ve grown fond of the 2-stage trigger from Wilson Combat in 2+2.

I've got Timney single stage, Armalite 2 stage, Armalite NM 2 stage, Larue MBT, Rock River 2 stage, and Rise Armament single stage 3.5lb. For a single stage the Timney is nice, it was also the most expensive trigger I have. It is a drop in trigger. It has two set screws in the bottom that put pressure on the trigger pins keeping them in. The Armalite NM is a factory trigger in a gun and is also very nice that I would rank up there with the Timney. Rise Armament is a drop in trigger that requires anti walk pins. It is a cheap functional trigger. Not the best out there and not the worst. The best trigger that I have found for the money is the Larue MBT. Curved or straight bow doesn't matter. It has come to ever new rifle I put together gets the Larue trigger. They are that good.
