great product would recommend to anyone only issue I found was the holes were very snug on the drill bits and I felt like the drill bit should have had a little more clearance in the holes but over all great product I have completed 3 lowers since I received it

I am impressed with the quality of this jig. I used the online video instructions and this jig worked perfect. I can't wait to do another lower.

Got it in yesterday, and spent all last night working with it... until I noticed it was almost 1am and figured I better get some sleep before I had to go to work.

This thing is solid!! My first use was actually a polymer 80% "jigless" lower. The lower had little pieces that stuck out to show were to drill. These didn't work well the 1st one did. The 5/32 bit wanted to wander. Plus the fire selector hole is a little low on thier marking - leading to some issues (others found the same thing). So this time I cut the little "pimples" (what is the opposite of dimple anyway?) off, and used this jig instead. Worked beautifully!! Fire selector hole is in the perfect position. No fitment or timing issues at all.

Then I started using it to finish up a forged Al. lower... no problems there either. The threads on the alignment tool (black piece on the right that screws into the buffer ring to align the top plate to the lower) were a little tight. I tried a buffer tube and found the same thing... The one suggestion I would make to JT, and a quick mod I made is to drill across the alignment tool. It's slick as it comes and with the tight threads on the lower I couldn't get a good grip. But you still need to be careful not to cross thread... probably why they didn't do it. A tap would be ideal/proper, and I found some (1 3/16-16p) but not cheap $60 and up. This I drilled across the round alignment piece, I was able to work it through without too much trouble. Just work slow.

80% jig
I ordered on Monday and received my shipment by Friday of the same week. I have not used this jig to complete a lower yet however I have to say I am very pleased with the quality this jig is made. I'm sure it will work as well as expected. I will update this after I have the time to complete my lower. As for now I will give it 5 out of 5 star because of the quick shipping and for what I rate as excellent quality and material.
