Anyone know where to find such a thing, i cant seem to find a 80% cheaper then a 100%. i just enjoy "building" them. http://www.ar15plus.com/ is about the best deal so far at 135.00 but you would need a jig to complete so that makes it 200+ |
Just a little FYI for ya....... You'll spend more than $200 for a quality jig, the taps, drill bits and other accoutrements that are needed to properly complete an 80% lower - and that does not include the proper machinist's skill in order to do this job properly. I paid $300 for all my jig and parts alone, (NO 80% lower here) but then it was considered the very best jig at the time and the guy I bought the stuff from had ruined several lowers before he got one completed, (apparently there was some that "machinist" skill stuff he lacked). Without some serious help from an expert machinist just setting up the drilling press would have beyond my experience level - lots more to this work than some folks think, but then heck you may have these skills....  mike |

Get yourself one of them forging blanks (bottom of page)...that's the only way it's ever going to be cheaper than a completed lower. It is a little more work than drilling and tapping a few holes, though. -Jbot ETA: "The receiver can be finished by any competent machinist." I consider myself a competent machinist, but it would take me a while to get this done without a CNC mill handy. |

Try tanneryshop.com for 80% stuff. What equipment do you have available? If you are going to look around for forgings, be aware not all look the same. I bought a raw forging that looked disctintly odd, without rounded fillets where you would expect them. I bought a bunch from Anchor Harvey that look great and are dimensionally very similar. I would feel ripped off if a raw forging cost more than 25 bucks. Lot of places sell them. |
if you have access to cnc machines just do one out of billet - www.cncguns.com/projects/ar15lower.html and you can get the solid model from here - www.cncguns.com/downloads.html for your cam program. then all you need is a 5x2x8 piece of 6061 or 7075 t6 Al
