Alfred Richardson –
Parts look good, have not installed them yet. they were priced right.
Dale Lyster –
Fit was excellent. More trigger up take than hoped for. Indeed a 4.5 lb trigger pull and crisp as described.
James Sparks –
Great stuff!! Couldn’t be happier. Top quality for sure. Love thus place.
Gabriel –
Purchased to complete the lower I printed and everything works perfectly. I also thought it was nice that the kit included a threaded pin for the bolt catch that threaded right into the print. Appears to be the cheapest LPK for lr308/ar10 on the internet. Not sure if all the parts were from the same supplier/manufacturer but the bolt catch was stamped with KAK. If you’re looking to build or complete your own ar-10 I would highly recommend this LPK.
Adam Stone –
Just a heads up for people buying this for an Anderson Manufacturing lower. Everything works, but there are Anderson Proprietary parts (front takedown pin and bolt catch) that work better for the Anderson lowers. The Anderson takedown pin has a flat side for it to seat all the way and their bolt catch sticks out a little further. The parts in this kit all fit and we’re functional, but the pin not seating all the way bugged me, so I bought just the proprietary parts from Anderson for $15. The bolt catch in this package worked, but the proprietary bolt catch did work better with the Anderson lower.
James Woods –
Have not had time to use the kit , but it looks good.
Joshua Hedrick –
As always, 80% lower has great quality. Every build I buy gets easier and easier. The fulfillment of building my own firearms is second to none. I recommend them to everyone. I for one am a customer for life.
