I'm not usually a 2 stage AR trigger guy. So when Bushmaster asked me to review one of their new DM2S triggers, I was a little hesitant. But, since I really like trying different triggers out, I couldn’t pass up the opportunity. When it showed up, I was pleasantly surprised with how much I liked it. The DM2S is a good 2 stage AR trigger.

If you haven’t heard, Bushmaster recently came under new ownership. What does that mean for you, the consumer? Most likely they will be introducing new products, like the DM2S, suppressors, and new updated rifles. All made in America.

The DM2S is a little different then most aftermarket triggers you might be used to. It is not a cartridge style. Instead it resembles a Mil-spec trigger. So when you install it, it installs in two pieces, just like that old GI trigger. But, it is definitely not your old GI trigger. However, the trigger shoe is a spot on match for a GI trigger. So the trigger shoe curve will be recognizable to all. In fact, when you look at the exterior of a rifle with the DM2S trigger in it, you can’t even tell that it has a match grade trigger installed.

I guess an explanation of what a “2 stage” trigger is, is in order. A 2 stage trigger has 2 distinct actions. When you first pull the trigger, a lighter weight pull is felt. This lighter pull can feel like take-up, but in fact, it is part of the design. Once you pull through the first stage, you come to a stop, or wall. This is the second stage. The second stage is a heavier pull weight that is added onto the first stage's pull weight. Then you add a little more pressure, and the trigger breaks, thus firing the firearm. 2 stage triggers are sometimes used by those wanting to “stage” the trigger to get that little extra accuracy. By pulling through the first stage, a shooter can then make slight accuracy adjustments before breaking the shot. Or if the shooter decides not to take the shot, they can simply just release pressure to reset the trigger back to its original starting point. The DM2S that is here, measured around 1.5 lb pull for the first stage and 4 lbs for the second stage. So the DM2S’ second stage adds 2.5 lbs to the first stages 1.5 lbs, thus giving the total pull weight 4 lbs. Bushmaster publishes lubricated and unlubricated pull weights, listed in the FNB’s down below. The 4 lb weight, I measured, was with a lubricated trigger. It was only slightly higher before I lubricated it, maybe 0.25 lbs heavier. The DM2S’ second stage pull is crisp and clean. I was pretty impressed with the trigger break. It also has an excellent reset.

As mentioned, I’m more of a single stage trigger guy. However, the DM2S isn’t something to turn away. I was pleasantly surprised at how fast I could shoot this trigger. I ran some rifle Bill drills with it and they were about 0.30 seconds slower. That’s 6 shots on target at 7 yards, in 1.7 seconds with the DM2S. Not quite as fast as a super light single stage, but still fast. I can also see where the 2 stage has advantages when shooting from a bench, or prone, or for accuracy. Staging the trigger and then pulling through the 2nd stage can really help staying on target. With the trigger only having a pull weight of 4 lbs, it doesn’t lend itself to moving you off target like a heavy trigger pull weight can.

The DM2S is a non-adjustable trigger. There is nothing to set for pull weight, over travel, or anything else. That being said, the DM2S has a little bit of over-travel, but not much, maybe 0.050”. Since it is a 2 stage trigger, pre-travel is included in the first stage. I did measure it at around 0.150”. The trigger break measured a little under 0.100”, so I’d say about .080”. Therefore, the total trigger movement, to get the trigger to fire, is around 0.230”, or just under ¼ inch. Reset on the trigger seemed to be around 0.100” since you don’t need to reset the trigger all the way through the first stage, only to the beginning of the second stage.

The DM2S trigger, from Bushmaster, actually surprised me. For a 2 stage, dedicated marksman style trigger, it is pretty good. The pull weight is good, it has a crisp 2nd stage, and a forceful reset. If you are the type who likes 2 stage AR triggers, you might give the DM2S a try.
