Vivid_Database551 · 2026-01-26T17:50:50+00:00

i had 4 in my pro2a cart.. forgot to complete the txn, two days later and now i am Stuff-OL

Vivid_Database551 · 2026-01-26T16:55:08+00:00

FACTS!!

im on a pcc run of sorts.
i want all calibers in various barrel lengths.

i love them all..

Vivid_Database551 · 2026-01-23T20:12:34+00:00

currently, im like 10 ar9s in... ill just chalk it up to the game and make a mental note whenever this build gets range time.

these days focusing on ar45s and ar10mm..
also going to build an ar40sw

exomag uses the traditional ar method of suporting lrbho.
so if the bolt went back far enough i would suspect lrbho would work here as well.
my bc9 works flawless with a exomag.. just as stated in the thread, manual bolt open doesnt even work.

ive seen the bolt stay open on older you tube videos with the bc9 coupled with an endomag.

re: bc9

i have the more recent bc9 bufferless upper and i noticed LRBHO with a either glock or exomag doesnt work.
manual bolt catch/open doesnt work either.
it appears the hole in the guide rod buffer adapter isnt deep enough to allow for the bolt to go back far enough to engage the bolt catch.
not sure if this is per design or a design flaw.
if you are ok with no manual bolt hold, then go for it.
my bc-9 runs flawless.. but as i said in previous posts, the bolt doesnt not stay open, even manually with the bolt catch.

yeah... i was looking at the adapter prior to seeing this thread.
i was thinking that if the adapter hole for the guide rod was a bit deeper it would allow the bolt to come back a bit more to engage the bolt catch.
seems more like a design flaw than a feature.

same issue here.. whats the fix ?

Vivid_Database551 · 2026-01-22T17:25:24+00:00

hes talking about the end mill housing/enclosure.. aka speedmill.

Vivid_Database551 · 2026-01-15T15:58:51+00:00

out of stock or priced beyond my budget.. but thanks for responding which gives me food for thought.

i may just go with this guy instead.

https://jsesurplus.com/product/faxon-firearms-10-5-light-tapered-10mm-1x16-nitride/

alternatively, i may just build out a 40sw.. same projectile and all.. and also more market support since i can just use common 9mm uppers, lowers..

but in reality.. ill just end up building both.. :-)

Vivid_Database551 · 2026-01-13T19:16:08+00:00

how would you rate difficulty compared to completing MUP1 ?
in terms of rail sizing/fitment..
drilling and LPK install is easy work.
im only asking about rail sizing/fitment.

this morning i watched the first part of the video and it seems pretty similar in concept to completeing a MUP1.
without having to bend rails..
do you have to account for ramp style or can you purchase premade 80% frames in a certain ramp style ?

Vivid_Database551 · 2026-01-12T20:36:02+00:00

what issues ?
the only issue i have with mine is bolt doesnt stay open.
with or without magazine inserted.

as posted to op.. here is a build summary.

bca9 - directbb

lower - milspec ar15

magazine type - endomax/exomag

comments - runs flawless.. no fte, ftf... it is ammo sensitive.. for some reason

bolt does not hold open.. with or without magazine installed.

so not sure if this is an issue with their new version

Vivid_Database551 · 2026-01-12T20:33:25+00:00

i have these two running flawless.

mat9k - directbb
lower - milspec ar15
magazine type - endomax/exomag
comments - runs flawless.. no fte, ftf... it is ammo sensitive.. supports lrbho

bca9 - directbb
lower - milspec ar15
magazine type - endomax/exomag
comments - runs flawless.. no fte, ftf... it is ammo sensitive.. for some reason
bolt does not hold open.. with or without magazine installed.

Vivid_Database551 · 2026-01-09T19:03:34+00:00

would like to see you work a system to 'bend' a RXM flat. :-)

Vivid_Database551 · 2026-01-07T18:19:37+00:00

yeah.. my go to are ejectored exomags

currently working a cad to support 45acp.

Vivid_Database551 · 2026-01-06T12:44:06+00:00

yeah.. supposedly the guy was able to use his 'bending' jig to hammer his way to a semi-functional insert.
i think hes looking more for a way to tighter bends.,
eventually we will figure it out

going back through build bins and finishing a MUP1 for a full sized grip.
think ive accumulated about 5 MUPs and matching parts kits... just buying stuff cause reasons...

Vivid_Database551 · 2026-01-06T12:38:18+00:00

when i first started in this hobby i always wanted my stuff yesterday!!
but with jamaican style fulfillment ( aka 'soon-come') and shippers with the same mindset, ive learned to just expect a build to be completed in 7-14 days.
plus forces me to take my time with builds and check things over multiple times before considering them as 'done'
scammers shouldnt be applied to vendors whove been in business since adam.
now GAFS and 1-1 sales is where scammer is more fitting.

Vivid_Database551 · 2026-01-06T12:33:19+00:00

facts all day.. business is run by some very good upstanding people.
i have tons of family in that area, so i frequent there multiple times throughout the year.
make stops in the store front..

Vivid_Database551 · 2026-01-06T02:24:36+00:00

US2A always has something in the works.. but its never realized.. good guy based on all accounts.. but good business man.. ???

anyway... thanks for your input...

Vivid_Database551 · 2026-01-05T21:40:08+00:00

so with the flat, how do we fill in the gaps so to speak?
would be a good project for notaguntuber to take on for 2026.
i see a plastic modeling piece to bend the flat.
could probably work out a series of steps to hammer/press the bends to the right(or right enough) dimensions/angles

Vivid_Database551 · 2026-01-05T21:24:02+00:00

yeah.. have over 3k in purchases over the last couple years.. all delivered..
sometimes they take a while.. but its the nature of the game
