Botach has the new "Gen 2.5" 1301T with the M-LOK barrel clamp and Beretta +2 extension and Mesa Urbino stock for $1099: https://botach.com/beretta-1301-tact...mag-extention/
Some notes about this even though it's an amazing price (to put it in perspective, the MT pistol grip stock costs ~$125 by itself and the Nordic or GG&G +2 extension ~$125 as well):
1. The chokes in these "LE" models are fixed cylinder chokes and are unremovable.
2. We do not yet know if the Aridus (or Briley) handguards can be used on these newer SKUs as no one's posted a "trip report."
3. Some people aren't fans of the Mesa Urbino stock (and don't find this out until trying it personally), and excellent price aside, you probably wouldn't be able to sell it if you didn't like it as it's an OEM part on this SKU.
4. Botach does have some red in its ledger as a seller. Most common complaint is they're exceptionally slow to ship out.
