Frames, small parts and the pins that finish them

Polymer80 Warehouse carries the frame families alongside the pins, springs, rails and parts kits that a build actually stalls on. Written by the people who pack the boxes. Tracked US shipping.

Lead guide
The small parts that stop a build: pins, springs and detents

On polymer80 pin kit. Written from kits finished on our own bench, not from a catalog.

The parts nobody remembers to order

Frames and slides are the easy part of a build to plan. What stops people is a missing locking block pin, a trigger spring that walked off the bench, or a slide lock spring that was never in the kit. Polymer80 Warehouse keeps those in stock and lists them next to the frames they belong to, so the order that leaves here is a build that can actually be finished.

Reader questions

Answered plainly

Do you sell complete firearms or conversion devices?
No. Unfinished frames, lowers, jigs, slide assemblies and small parts only.
What is the difference between the RL556v3 and the G150?
Both are polymer AR-15 80% lowers. The RL556v3 has a solid core, flared magwell and a threadless grip design; the G150 Phoenix2 has an integrated trigger guard and a threaded, reinforced buffer tube housing. Each needs its own jig.
Does a PF940C take Glock 19 magazines?
Yes. The finished PF940C runs standard 15-round G19 magazines and larger G17 magazines. The PF940SC takes G26 10-rounders and longer magazines with a sleeve.
What tools do I need beyond the kit?
A drill or drill press, a vise, a file, safety glasses and cutting oil. The jig, drill bits and end mill are in every frame kit.
How long does shipping take?
Orders leave a US warehouse within one to two business days by tracked carrier. Frames and receivers go only to states where they are legal; parts and jigs ship everywhere in the US.
