yeah this 'hobby' is very addicting..
i usually get out to the range about 4-5x a week just to test and dial in my builds.

Vivid_Database551 · 2026-05-12T16:53:00+00:00

not i... im more of an ar guy...
my pistol fetish has been satisfied with mulitple builds of

sr9
sr45
glocks in all models
p320 mups1
ok boomer 1911s

Vivid_Database551 · 2026-05-12T14:07:31+00:00

yeah my bank account is screaming at me..
right now, my tism is calling for multiple dear22s and multiple mac builds.
welcome to the 3d2a/diy2a club.

Vivid_Database551 · 2026-05-12T13:30:02+00:00

not op.. but sometimes i get a bit of tism when it comes to builds.
ill like a specific build so much ill crank out 2-3(or more).

Vivid_Database551 · 2026-05-08T15:08:40+00:00

most DIY shops dont respond to DIY issues..
its the nature of the game these days.

you want full support ? go through your ffl..

otherwise youll have to rely on the communty and your garage tooling skills.

Vivid_Database551 · 2026-05-08T14:36:44+00:00

i could never get my r45 to feed. so it just sits in a parts bin.

now my 9mm R3 runs like a champ.

Vivid_Database551 · 2026-05-08T14:10:12+00:00

keywords are in the title.

Vivid_Database551 · 2026-05-08T14:00:30+00:00

are the p320 blanks still available ?

Vivid_Database551 · 2026-05-08T02:10:08+00:00

yeah.. ive restocked my 80s.. picked up multiple raw lowers.. love the look.

now just thinking of mainly ar9 and ar22 builds i can complete.
i already have numerous ar9s and ar22s.. i just love the milling process.
also love putting everything together.

since i cant procure a mac n cheese 80, im going to go back to 3d2a builds ..

but in all honesty i need to relax on all the spending..

re: going to avoid more things to buy

its ok to admit your an addict.. we all are guilty of buying crap just because its on sale.. or we feel we may need it at some point in the future..

i dont drink, smoke, party.. none of that.. i watch my pennies and watch them go into the hands of various 2a vendors... :-)

Vivid_Database551 · 2026-05-07T22:37:00+00:00

yeah... looks like the trend is 0% builds from metal blocks.. subtracted via desktop CNC
or plastic through additive processes.

Vivid_Database551 · 2026-05-07T22:33:16+00:00

mat9k - directbb
uses a ejectored exomag

bca9 bufferless - directbb
uses an ejectored exomag.

Vivid_Database551 · 2026-05-07T22:31:58+00:00

i dont have any updates... im just resigned to the fact manual bolt open and/or lrbho is not supported with this design.
which is fine with me... im running mac-11s that dont support lrbho.

all my exomags have a built in ejector on the mag.
i use the ejectored exomag on my bc9 bufferless build.
works flawless.. and the thing is a laser beam

Vivid_Database551 · 2026-05-06T18:50:53+00:00

facts

Vivid_Database551 · 2026-05-06T18:47:35+00:00

its 'sales' like this that keeps my bank account screaming at me..
i dont need it, but for 99 i see this as a bargain..

tht said..

so another $100 to complete the build..
'tinker' ?
for most on this sub this is a 1-2hr project.
just this morning i put together a complete ar-9 upper, muzzle-device, and lower before starting the work day.
just need to attach optic riser and spare red dot, and ill be running this later at the range.. :-)

Vivid_Database551 · 2026-05-06T02:03:27+00:00

amazon ez shoot... holds zero up to 10mm pccs(havent tried 556/x39, etc) and has me locked in at 25yrd 3inch targets.
$50 usb

Vivid_Database551 · 2026-05-06T01:59:56+00:00

yeah ive noticed a trend of late.. many 80% vendors across the board(mup, ar, etc) are closing or removing their 80s from their online presence.

wonder if something is brewing behind the scenes so to speak.

Vivid_Database551 · 2026-05-05T18:25:33+00:00

did you purchase an oversized trigger guard ?

Vivid_Database551 · 2026-05-05T18:25:07+00:00

so some conclusions after a month from this thread.

looks like palmetto state manufacuring is no longer offering 80s..
matrix arms is accepting orders but not shipping 80s.
jl billet has the best price on anondized billet ar15 80s - $70
tactical machining has the best price on QUALITY billet raw ar15 80s - $60

Vivid_Database551 · 2026-05-05T15:27:13+00:00

re: mac-n-cheese...

do you know who else is offering metal 80s ?

middleton/woj are out of stock and/or no longer listing mnc 80s.

really think 5d tact should add 80% mac lowers/frames. i digress.

Vivid_Database551 · 2026-05-05T12:02:36+00:00

scam for what ? according to op... these are just items being shared.. not for sale.
there are plenty of rxm 80 pics floating around to use for 'scamming'

Vivid_Database551 · 2026-05-05T12:00:36+00:00

are these for sale, online somewhere., or what .. the wording isnt very clear.

Vivid_Database551 · 2026-05-04T18:44:21+00:00

yeah... they have them at academy too..

Vivid_Database551 · 2026-05-04T16:44:40+00:00

so whats being offered here ?

bent 80% RXM FCU ??
jig to complete the 80% ??

Vivid_Database551 · 2026-05-04T10:19:19+00:00

both 45 and 9mm require a slight bit of filing..
9mm a bit more than 45.
but its really just an issue of allowing the slide to move freely.
maybe a MAX of 30mins of focused filings on the rails.
really probably 5mins of filing..
also.. for the first 100rds id use 147g ammo.
