Quoted: Fellow build it yourselfers:
I am working on machining up an AR lower from a casting and realized (too late) that I had drilled the trigger pin hole to .204" diameter instead of .156! he Has anyone any ideas as to how to salvage this lower?

Hi Guys,
i'm new to this forum and i would like to say Hello from the UK!
i have been reading you threads and post for some time, approx 18 months and find them very interesting!
i've only just got around to joining and posting my first post
havethis was my first attempt at building one, and i done the exact same thing and forgot to change the drill bit and then drilled the hole too big
herethe best thing about the kit you only need a household Blowlamp to use it! and no expensive alloy welding equipment, or searching around to find someone with a TIG welder.
the kit takes a little practice on some scrap alloy to master the technique but the end resaults were very good,
i then filed down the excess braze and then re-drilled the hole to the correct size
hesei also have a AR 80% lower drill jig with most drills and all the long detent drills + The bluebook guide by Ben Hughes for sale at the momnent.
Hope this helps, sorry for blagging sales on my first post...i thought it may help somebody
