Finished up with the EPC‑9 build. I’m planning to get this one cerakoted, but I can’t seem to find a local shop that does it. If anyone has any suggestions or knows a place that does great work and ships in and out, I’d really appreciate it.

I’ll be testing it out this weekend!

The wait is excruciating but its well worth the wait! I've been renting this at my local range endlessly for a couple months in anticipation.

Ordered: 2/22/2026

Delivered: 5/4/2026

The color is significantly different than the build preview. I was expecting a hyper silver whitish build and this is closer to a champagne / tan color. This is actually a good thing because I was regretting my design before it arrive so it was a pleasant surprise that the reality of my choices were darker than my preview.

So far I only added the mag extensions to the factory Glock mags but ill be doing the standard X300T-A and a dot. Unfortunately, I pre-ordered the 507 Pro Max back in February and there is no telling when that thing will release.

So glad its finally here!

Just about finished with this one. Hopefully I can test her this weekend. The quality of this receiver set is very nice, I dig the threaded rear detent and bolt catch, should be mandatory in this age. The milling is really nice. No LRBHO but I don't care.

My other builds are using the KYNshot buffer with flat spring, this will be my first time using the Armaspec buffer so I'm hoping it works out. I don't really care for the buffer sitting in there without a stop but we will see. I had to make and 3d print a 22mm spacer for the end of the buffer tube so that the uncompressed distance was the same as a standard buffer tube, not sure how that's going to go but it should fill that gap. Here is the parts list:

JRC Buffer Tube w/3D printed Spacer

SBA3

Houge Over moulded Grip

Battle arms xiphos upper and lower

Battle arms BCG

Battle Arms 9.5" handguard

Rise PCC trigger

Sons of Liberty takedowns, bolt catch and Safety

Odinworks 7.5" Barrell with Kaw XL Slim (soon to be pinned)

Custom 3d printed vertical

AT3. 85 riser

Holosun 512C optic

If I can find a good ceracoat guy locally, I plan the color. I don't even want to start with that rabbit hole .
