I’ve completed at least three lowers to date over the past year with just the one jig I purchased. The machining tolerance and quality of materials has really stood up to my user errors and sometimes cheap machining equipment I used. I definitely recommend and will buy more when they’re in stock

Show both sides of the side plates on website photos please. My lower does not have recess pockets in the side of the mag receiver. It was either shave lower at pocket area or flat mill the bump off your jig plate. This was not crippling but could have been avoided as both pieces are made both ways(with and without recess)

Elite builders jig works awesome. If you know anything about tools etc You don’t need instructions. Works gr8 on drill press with two way cross slide drill press vise. Make sure cutter edge is not touching jig. Just the smooth shaft . Take minimal depth cut each pass. Plates are numbered for the drilling process. Only need to know two total depths 1 3/8”. Selector area. 2” deep trigger area. Go slow. Take your time. I have a Bosch laminate trimmer with the offset base ( used for counter tops etc ). Bought some 1/4” end mills. Worked just fine. Can reach the selector area where a regular trim router base can not. AAAAAAAA++++++++++++.

Easy to set up and use, plates have depth written right in them which is nice. Originally wrong one was sent, called customer service left message 10 min later they called back and in about 5 minutes we had things straightened out.

No one will advise me with lowers to use with this jig so it’s useless to me.

I had to do some relief cuts and the side blocks to get it to fit my ambidextrous lower 80%, no big deal just letting you know it didn’t work straight out of the box

I purchased the Elite Builder Patriot 80% Lower jig package. I can figure out how to use it but, it would better if it came with some form of INSTRUCTIONS.The jig kit itself IS very well built.
