Description:
Black Dog Machine has been making this mag (and variants of it) for years. It is most similar to the CMMG Gen 1 magazines except this has metal feed lips. Overall it's a common and very standard magazine. Now-a-days it doesn't have the most functionality compared to the CMMG V2, S&W 15-22, etc. but it's still a reliable option for cheap .22 shooting.
Pros:
- Similar to the CMMG Gen 1 magazines. These are simple and reliable magazines
- Metal feed lips
Cons:
- LRBHO is only from the follower getting in the way of the bolt. No bolt catch support.
LRBHO functionality:
- Partial (bolt drops when magazine is removed)
