LPK
My stag LPK was put into my rifle in 2014, the selector was a little tight and took some use to really move freely, however I expected a little bit of a break in period; that's just how tolerances work. Standard grip, nothing to write home about but it doesn't flex and has not broken.
Aside from that, 6 years thousands of rounds still strong. Approx 1mm of creep (not soft and squishy but a swift pull to lock up), then a strong crisp break with a consistent duty weight pull, reset is positive and consistent. Even with this milspec pull weight I can hit sub moa and out run my carrier thanks to the tight action and clean break. No change in the consistency over 6 years, I am thoroughly impressed for the price. -

Lower parts kit
This is my first AR build. I think a set of instructions would have been helpful. However thanks to YouTube I was successful in my endever. My only other minor complaint is that the pins that hold the upper are not as smooth as the pins on my factory rifle. All in all a good kit for a good price. I would recommend it.

Very solid parts
Everything went up great on the non stag lower I bought.
Came with bonus rolled up roll pin (which I didn't notice 'til after I had the split roll pin in) and an extra mag catch.
The parts all seem very high quality and feel great on my build. I was expecting the trigger to be crap since everyone says mil-spec triggers are terrible, but I really like it. Mine feels crisp and light. Granted I'm now the proud owner of one and a half guns, so I'm no trigger snob. Still, though. Great kit all around.
