是不是半自動只有SCAR20S和MRGG-S可選？

#2 Re: 6.5 Creedmoor誰有經驗？
Here you go—SCAR 20S and MRGG-S added and everything lined up by design (DI vs piston vs classic), plus MSRP and first release year for the 6.5 Creedmoor variant (or the platform if that’s how it was introduced).

Quick design key
Direct impingement (DI): AR-style gas tube vents gas into the carrier (e.g., DD5, JP, Seekins, Ruger SFAR, MRGG-S, POF Revolution DI).
Short-stroke piston: Separate op-rod moves the carrier (e.g., SCAR 20S, LWRCI REPR MkII, POF Revolution piston, SIG 716 G2).
Long-stroke piston (“classic”): M14/M1A system (e.g., Springfield M1A 6.5 CM).
Notes on pricing & dates
MSRP is the maker’s suggested price when available; otherwise I used a prominent dealer’s listed MSRP / list price for that exact model/trim and noted it (those often mirror MSRP). Pricing fluctuates by finish/trim and over time.
Release year is specifically for the 6.5 Creedmoor variant when that’s how it was introduced (e.g., SCAR 20S 6.5 CM in 2020), or the platform’s initial commercial release when 6.5 CM has been a routine option (e.g., JP LRP-07).
