I'm a prairie dog hunter and plan to take my 20" heavy barrel AR 15 this spring. I plan to use the AR out to 300 yards with a 69 gr. Sierra. I bought a RRA two-stage trigger and it's great, a vast improvement over the stock trigger. My question is, who makes a single stage trigger with adjustable travel and poundage like you would find on a good varmit rifle? And how much? I take 2 Remingtons and 1 Ruger all with custom triggers with me. I find I have better accuracy if I can keep the triggers and scopes the same. Thanks |

I installed a JP single stage adjustable trigger along with their lightweight hammer in my CR6724 that I use for extended trips to the 'dog towns. I can get a reliable 2.5 lb. pull with no creep. I found that I had to readjust after the first (approximately) 200 rds. then it settled in just fine. I really like this setup because it feels more like my bolt action varmint rifle triggers. I can't remember exactly what it cost, but IIRC it was about $120 for both pieces from Brownells. |

Go to Brownells at the link below, do a search for AR15 triggers, you will have lots of choices. Brownells |
And I was still making good hits at range with the gun. Forget what scope I had on it. Something in the 3x9 or 4x12 range though.
+1, KAC is the only way to fly. (Oops I mean shoot). Its the best and most reliable 2-stage match trigger. Expensive, but well worth it. |
You know if you just use a M-203 with HE rounds, you don't have to worry about the heavy trigger. As for the light Single stage trigger, due to the design, you’re limited to around the 3 LB minimum pull weight and still safe. If you’re looking to go lighter than that, look into a Jewel Two stage. On these, you can get the pull down to just over 2 lbs. |
| Lots of choices, and you won't be disappointed with any of the triggers mentioned here. The KAC is more rugged than the Jewell, but I prefer the Jewell for my own rifle due to the level of adjustability. Of course, they're two-stage triggers, but both excellent. I put a JP single-stage with the low mass hammer in my Colt and it lets off at 2 3/8 lb. It's beautiful. I have another JP on the way from Brownell's for a carbine, but with the heavier trigger spring. |

Single stage trigger (set correctly) has no movement before break. The two stage design has primary sear slip until the disconnector makes contact with the back of the hammer, Once you hit this resistence, then the next movement will be the break. The two stage trigger is the primary tension (the light take up), then the added tension caused by the disconnector pressure on the back of the hammer before break. |
http://www.williamstriggers.com/ I am local to him. I have shot an HK91 with one of his set triggers as well as AR15s with his set triggers. The AR15s have about a 4-4.5 lb trigger pull before setting the trigger and the standard pull is very smooth and is a good trigger in itself. When you set the trigger though, it is just amazing. Like a 1.5lb trigger with no creep. Just line up the sights, set the trigger, slowly begin increasing pressure until it goes off. I can't see how a person could ever miss because they flinched with this trigger. It just always suprises me when it goes off. |
My Dad did have a gunsmith install the Jard...that is because my Dad and I are mechanically challenged. But it is a great trigger, and Dad is able to make some great shots with it. Also the Williams Set Trigger is great. I have one on my HK91 4 pounds and 2 pounds on SET. Williams Set Triggers can be found at www.williamstriggers.com Chris |

b_r_bray, The caveat in Brownells description of the JP trigger that mentions gunsmithing required in sear-block Colts refers to the older Colt lowers with the pinned-in sear block. No gunsmithing needed in the later Colts with the bridge in the sear area. What series Colt do you have? I didn't have to use a different trigger spring than what was provided in the JP kit in my installation to get 2.5 lb. let-off, but due to manufacturing tolerances YMMV. Yes, you do have to remove the trigger to replace the spring. If the need for that arises don't worry about it. The first time that you install an FCG the instructions might seem daunting, but once you do it you'll be surprised at how really simple it is. The proper sized punch is a good start. |
+1. The JP unit just dropped into my Colt. JP's literature is full of warnings about what you might have to do to make things fit, but it's not likely that you would have any problems. |

str8shot, I don't have a Colt, but a Colt clone A3. I hope that doesn't disappoint you. The first time I took it to the range the wind was blowing 10-20 mph quarter toward me and my beginning load shot a 3/4 inch group at 100 yds. Still have some trial loads to work up, but so far I'm happy with the preformance. I really appreciate your help and everyone else. Thanks |
edwin247, The best way I can describe the feel is simular to a compound bow. You pull the string back and the cam breaks over. In a simular way my RRA two stage has a short light pull, like it's gaining leverage. I feel the trigger stiffen and with a little more preasure the gun goes off. Maybe someone can describe the mechanics and my trigger may be quite different than others but thats the best descripion of what my trigger feels like. The bottom line is that it is extremely predictable and the pressure applied to the trigger does not pull the rifle one or the other as much or any (depending on the person holding the trigger). What's wrong with it for prairie dog hunting? Not a big deal but if you are pulling the trigger on a dog and he ducks down, my trigger does not return to its starting point. So the next shot will not feel the same and I don't feel safe with a gun that may fire any moment if bumped. Probably unfounded fear, but I've had guns with low poundage triggers bump fire before. No injuries other than a red face and the wrath of my fellow dog hunters, but safety is worth the cost of a trigger without this potential problem. Can anyone speak to this possiblity of a bump fire with a two stage trigger in this scenerio? |
Then your trigger is messed up. Yeah, I have heard of the bump fire too, if you are refering to a gun doubling through recoil. Now, if you are talking about jarring or dropping a gun and having it go off, that is bad bad bad! |

The dog hunters I run with would describe a bump fire as a rifle firing when the safety is off and the rifle receives a blow causing the rifle to fire. We check all unloaded rifles before going to the field by closing the bolt with the safety off and dropping the rifle butt first (allowing the barrel to slide through our hands) 6-8 inches to the floor. We started this check because someone resetting their trigger at the hotel without checking it. We got to the dog town and he rolled the bolt shut on the first round and it went off. It was pointed down range of course, but we now set our triggers at the sight in range, put some fingernail polish (I just openned myself for a comment or two) on the screws, let it dry and DON'T TOUCH IT until we are back at the range. Regarding the more important issue. Yes, my two stage trigger does not return to its starting position if I let up before firing. I will be in touch with the dealer today. Thanks 123whisper ! You can have my first born child! Rechecked my RRA two stage trigger. When I particially pull the trigger just short of the break point of firing, my trigger does not return to the beginning point of the travel by itself as in return spring pulling. But I can easily move the trigger forward to the starting point of the travel and the trigger acts like the trigger pull is starting from the beginning. Is that anywhere closer to normal? |
Nope. Not normal operation, but it makes sense from what you have already told me. What is happening is that the trigger is basically over center or very close to being there, and the second stage is all that is providing the additional resistance. It could be fixed, but your best bet is to have your dealer see if he can send it back to RRA. Basically the two stage should have pressures like this First stage + Second Stage then break Your trigger is more like this. First stage + Second stage - minus first stage then continuation of second stage - then break. Or at least that is how I interpet things. It is what happened when we went too far on my first RRA two stage. We got the second one perfect though. 4lbs 3 or 4 ounces and very smooth. My next trigger will be a Williams Set trigger though. Going to put in a new lower though. My PWA has somewhat loose fire control pin holes. As for your first born child, is she female, between the ages of 18-22, interested in firearms or at least tolerant, not completely ugly, and intelligent and schooled enough to carry on a conversation about just about anything? If so, count me in!

If so, count me in! Actually that is my last born daughter. She was hit by a deer (her words) while driving to work and now wants me to kill'm all! 22 years old college grad, works for Sprint and brings down a 6 figure income and single. Good looking? Well of course, smart people think she looks like me! ho I'll contact the dealer tomorrow and get working on a solution. Thanks! |
