Title: How to determine what generation Scorpion you own?
Post by: Silent service on January 22, 2018, 09:22:31 AM

What are the characteristics that determine what generation scorpion you own?

I?m trying to determine so that I can order the correct micro barrel and trunnion from HBi.

Metric thread is Gen 1, 1/2-28 is Gen 2.

If you can measure the feed ramp width, then 14mm is Gen 1, 15mm is Gen 2.

I pulled mine apart yesterday and did feed ramp work, measured it the same time and it is confirmed as 14mm (micrometer said 13.96mm, close enough).  I also confirmed with In Lead We Trust that mine is indeed Gen 1.  I got a barrel complete with trunion coming from ILWT for a micro-K conversion.  Rob also confirmed that they tested it with JHP (although not guarantee it will work with all JHPs, certainly to be expected).

If you're interested in a true drop-in barrel conversion and not have to monkey with existing barrel/trunion, check out ILWT site https://www.inleadwetrust.com/collections/cz-scorpion-evo-iii/products/scorpion-evo-micro-3-lug-1-2-28-tpi-custom-barrel-trunnion (https://www.inleadwetrust.com/collections/cz-scorpion-evo-iii/products/scorpion-evo-micro-3-lug-1-2-28-tpi-custom-barrel-trunnion)
