"This trigger is excellent. Only took a few minutes to install in my Prof. Ordnanace Carbon 15, and I couldn't believe the first few dry fires! Very smooth, short stroke trigger with very little overtravel. The original single stage trigger on my rifle was good, but this one just blows it out of the water."

"I ordered this trigger about 6 - 7 months ago. I liked the idea of it being a self contained unit, so without touching one in person I gave it a shot. I was very pleased with the results, it's a light pull, clean break, with no creep. The only downside is, after dropping this trigger in all my other ARs feel like crap. :) I plan on ordering another one pretty soon."

"Great purchase. Easy install and a great fit - no gunsmithing. This made a big difference compared to the factory installed trigger from Bushmaster."

"My Bushmaster AR-15 has had a number of problems, including a very difficult 8 pound trigger pull. Finally got fed up and ordered the Chip McCormick Single Stage Drop In.1. Service was outstanding, Fedex delivery right on time.2. Don't forget to remove the safety, before installing, and remember the spring and detent is in the GRIP...Otherwise you'll be looking for a couple small parts.3. The trigger drops right in, the supplied pins and clips fit perfectly4. The whole job takes about 15-20 minutes.5. The trigger is superb, better than any of my other rifles regardless of make or type. 6. No problems with assembly, fit, safety check, they even supplied extra clips in case you lose one of the teeny things. I highly recommend this trigger assembly. Dan G., Cape Coral, FL"

"Received my McCormick Trigger, and put it in my 24\" Bushmaster today.Installation took only 20 minutes or so! Went to the range to check it out, and, was thoroughly pleased. No take up or creep evident, and let-offwas nice and crisp.I would recommend this product to anyone using an AR for target or varmint work!"

"I used a fellow shooters 20\" AR with this trigger installed at the range today, as well as his M4-style AR with a stock trigger group. I'm going to be making a place in my first AR build budget for this trigger, it's worth every penny."

"Installed in a DPMS LR 308 in just minutes. Trigger fit and function are perfect. The trigger breaks cleanly at 3.5 lbs. The perceived pull seems like less. A very good product. I highly recommend and I will buy another."

"Installed this trigger group in my Bushmaster and I more than pleased. Installation was a no brainer and took about 15 minutes from start to finish. The trigger has a crisp, smooth let off that not only impressed me but all my buddies at the range who gave it a try. This trigger is well worth the money and it does wonders for the accuracy of your AR."

"Install was clean on my Stag Arms 2T. The fit was good but it took more than just pulling the hammer, and trigger pins to get it in. You also have to remove the selector/safety, because the single stage trigger assembly is all one piece, trigger, and hammer in one. After that was out, it slid smoothly in. Very crisp trigger break. With the selector on safe, the trigger moves 1/10th of an inch, but does not fire. This creep is not apparent when fired immediately after cycling."

"I don't really know much about AR-15's as I am new to the weapon. But I do know enough to know I didn't like the stock trigger on the stag I bought. So I looked into alternatives and I am glad I picked the Chip McCormich Tactical Trigger. I had to look up removal of the safety (that is how little I know about the AR) but after I figured that out - the install was a snap. Literally it took about 10 minutes. The trigger feels great and I can't wait to go out and put a few live rounds through the thing....Come on Saturday...."

"A easy to do drop in trigger system that will improve the AR rifle. I got it installed in 5-10 minutes. It was a perfect fit & works well, no problems. It is a huge improvement over the stock factory trigger that came in the AR-15."

"I installed this trigger in about 15 minutes. The trigger is smooth as silk. This is much better than the stock trigger."

"This trigger is all It's cracked up to be! It arrived quickly. Instructions are not explicit, but you can figure it out easily if you know your way a little around an AR(and some common sense). It took 5 minutes to remove the normal, heavy, gritty stock trigger and about 15 minutes to install the CMC. It took longest to get the U clips on the pins. The new trigger has very little takeup and absolutely no creep. It feels lighter than the advertised 3.5 lbs. And yes, it does have the proverbial \"glass rod break\". Excellent quality and value for the money. Right up there with bolt=action triggers. I will definitely buy a couple more for my LR-308 and Bushmaster M-4."

"Great trigger for the price-installed in a Del ton AR 15 in about 15 min-way better feel pull and no take up before glass break snap."

"SLIDE-FIRE uses these with there .22 model of bump fire stock. This trigger is light enough to bump fire an AR with .22 conversion. Makes bump fire with .223 super easy. I prefer curved trigger, but straight should work just as well. Pull pressure is very light, and break is crisp. Maintaining pressure when re-setting keeps you ready for next shot. This product is perfect for my application. Since it is a drop in the trigger and hammer pins are clipped in place because there is no spring pressure to hold in place. This may be perfect replacement on older receivers where pin holes start to wobble. OK BUMP FIRING could be a waste of ammo, don't do it all the time. But as close to full auto we used back in the day, (ARMY) with M-16 A1, still fun."
