Decent kit, Not sure about the trigger

Decent kit. The trigger seems to have a 1st stage under 2 pounds and the 2nd stage feels closer to 3.5-4 lbs, haven’t verified it though... It still is smooth and has a crisp break, The reset is quick. In
The pictures it shows 1005 tactical etched into the trigger and hammer. The trigger Group I got has no markings or stamps proving its a 1005 tactical. Over all it will do the job.

Thanks for sharing your feedback, Nicholas. We're glad you're satisfied with your purchase. Cheers!
Great LPK/trigger

LPK was outstanding and the first the money the trigger breaks very clean. Definitely worth the money.

Thanks for sharing your feedback, Michael. We're glad you're satisfied with your purchase. Cheers!
Good product

This looks like a very good product. The parts look very well made and look very well polished. Doesn’t show any rough tooling marks. I just received the product so haven’t been able to install yet hopefully everything will go in very well without any issues. Will buy from AT3 again

Thanks for sharing your feedback, Zach. We're glad you're satisfied with your purchase. Cheers!
2 Stage Trigger

I haven't had a chance use yet still putting my 300BlkOut together. But from what I can tell from dry fire it's extra smooth and I can honestly say just from that I will be buying it again in the future.

Thanks for sharing your feedback, Aaron. We're glad you're satisfied with your purchase. Cheers!
Great parts kit at an excellent price

I purchased this for my first AR build and could not be happier with the quality, especially for the price. I had every intention of putting this together and in the future upgrading the trigger to a Timney or Geiselle. After running several rounds through it I could not justify the added expense. This trigger is smooth, has a perfect candy cane pull, an audible reset that is a good combination of short and smooth, and went together easily. I would highly suggest this kit and will be purchasing again for my future builds.

Thanks for sharing your feedback, Ryan. We're glad you're satisfied with your purchase. Cheers!
