I've gotten 2 Model 1 kits...a 16" lightweight, and a 16" standard...both CARs.
One kit had a major problem, but Model 1 made it right with no guff, I had to send it back, but had the repaired one back within a week.
They do scrimp in quality on the parts kits pieces, like springs, but they go together with little trouble...you might have to snip a couple of coils off the detent springs.
Both guns function flawlessly, and the 16" standard kit has done sub moa with the latest hand loads I put through it, which I've started to tweek just for that rifle.
You can't beat 'em for the price, but I don't know how their overall quality compares to J&T or M&A, which are more expensive.
I've heard nothing but good stuff about the J&T kits; in another lifetime, when I can afford it, I'll try one of their kits so I have something to compare to the Model 1.
What style of rifle are you looking to build? 16", 20", etc? Let me know, I can make some suggestions.
Here's the 16" standard kit...I've pimped it out a bit lol.
