I'm sending my MPX barrel to be chopped and re-threaded by ADCO. I plan to run my SF Ryder 9 via direct thread until my Revolution 9 gets out of NFA jail. Once I get the Rev9 I plan on doing a 3-lug set up.
Which leads to my question. The Griffin Armament 3-lug adaptor is set up for 0.625 threads. IIRC standard pistol thread depth is 0.40. Any issues with attaching the 0.625 3-lug adaptor to a 0.40 barrel? I assume the best approach is to thread the barrel to 0.625 and run a spacer on the SF Ryder 9. Would love input from the hive. Edit: for proper GA thread length |
| Sorry wrote the wrong number for GA 3-lug adaptor thread length. It is .625. Link to adaptor. |

If the Ryder can index off the muzzle, have it threaded to 0.625" and don't worry about a spacer.
If the Ryder can only index on the shoulder, thread it to 0.4". The only downside with that is that you may get carbon/lead fouling on the on the last .225" of threads on the 3-lug adapter which would make it difficult to thread onto something with 0.6" threads should you try to reuse the adapter later on. |
