Not just target rifles can benefit from a great trigger, as your defensive carbine or AR pistol can become a bit more predictable and user friendly with a precision trigger. I was sent the Standard Manufacturing STD-15 curved drop-in trigger for consideration.
We installed it in a Barnes Precision Machine 7.5″ AR pistol chambered in 5.56×45. The factory BPM trigger was not bad, breaking at six pounds with some take up and overtravel; the STD-15 breaks about three and a half pounds with minimal take-up or overtravel. While that may not seem like much, it was quite noticeable during live and dry fire.
The STD-15 features Anodized Black Housing, Stainless Steel Bushings, and a Nitrided Tool Steel Fire Control Group. All contributing to longevity and ease of maintenance.
This trigger setup can be curved, shown in the review, or straight depending on which you prefer. Dropping in an AR trigger is quite simple, and Standard Manufacturing sends you everything you need parts wise to get the job done.
During live and dry fire, we experienced no issues with the trigger, and everything on the rifle ran as it should, indicating the trigger is built to correct mil-spec external dimensions but far smoother than any mil-spec trigger. At $125 MSRP, this is a worthy upgrade that is, in the grand scheme of things, very affordable.
