Frequently Asked Questions

How do you disassemble the PSA Olcan bullpup conversion?

To disassemble the PSA Olcan, first ensure it's unloaded. Push the takedown pins from right to left using a punch. Then, lift the upper receiver straight up from the lower receiver. Maintenance on the lower receiver is similar to standard AR-style platforms.

What are the key differences between the PSA Olcan and a standard JAKL disassembly?

The primary difference is the takedown pins on the Olcan are pushed right to left. Crucially, the Olcan upper must be lifted straight up to separate from the lower, unlike the standard JAKL which rotates.

What are the legal requirements for using the PSA Olcan with shorter JAKL uppers?

If you use a JAKL upper with a barrel length under 16 inches with the Olcan lower, it must be registered as a Short Barreled Rifle (SBR) with the ATF. This typically involves a tax stamp and specific legal procedures.

How do you remove the cheek riser from the PSA Olcan?

To remove the cheek riser on the PSA Olcan, simply push it towards the rear of the upper receiver. This allows for easier access to the upper receiver for cleaning or swapping between different firearm platforms.
