I am thinking about trying a 45acp build using this lower as I already have G21 mags on hand.Well I have done the 9mm with endomag. Maybe ill do a 45 in the future...
It looks like fun gun.I originally built this back in the 90s and recently updated the upper. .45 acp. My favorite carbine that has won me a few trophies in competition shoots. I love this gun and have had it for 26 years.

What weight buffer and spring type are you currently running in it?I originally built this back in the 90s and recently updated the upper. .45 acp. My favorite carbine that has won me a few trophies in competition shoots. I love this gun and have had it for 26 years.

Looks those 10mm products are OOS.If I bought one of these bolts and a 10mm barrel I could cover 10mm and probably shoot 40 put it too. So many options and so little time.

Back when I built it, we did not worry about all that technical stuff. It is a AR15 carbine buffer and spring. What weight? I have no clue. It has always run like a Swiss clock and has never failed me.What weight buffer and spring type are you currently running in it?
A banshee 45 Upper can run 45 super no problem. That's about 1300 FPS with 185 grain ammo.Oh now I am getting ideas too lol.
I put my 9mm together with a 5" barrel and a long (4.5" i think) forward compensator. I can get about 1350fps out of it with 115grain. The same ammo did 1200fps out of my polymer 80 G17 build. Just under 1200fps out of my SS80 G43.
I wonder what velocity the 45acp could produce?
I am still tossing around the idea of an AR45 build. I found cheaper prices on barrel and bolt but a dedicated glock 45acp/10mm lower is still running about $150 shipped from Joe Bobs. Slick side upper and barrel are $124 total shipped from Gorilla Machining and a KAK bolt is about $115 from DTT. This set up would allow me to easily change over the barrel to 10mm when a deal comes along on a 10mm barrel.I am thinking about trying a 45acp build using this lower as I already have G21 mags on hand.

The only other parts I might need are buffer related parts.
Pretty inexpensive compared to what other people (me) are paying...I am still tossing around the idea of an AR45 build. I found cheaper prices on barrel and bolt but a dedicated glock 45acp/10mm lower is still running about $145 shipped from Joe Bobs. Slick side upper and barrel are $124 total shipped from Gorilla Machining and a KAK bolt is about $115 from DTT. This set up would allow me to easily change over the barrel to 10mm when a deal comes along on a 10mm barrel.
Any reason to think these components will get much cheaper in the near future?
I picked up a glock pattern PSA 9mm/40 lower from a WA member a while back but haven't put it together yet. I have multiple 9mm uppers already but none for the 45 or 10mm cartridge.If I wanted a Glock pattern AR9 I would snoop around this (among others) website :
