Thanks for the heads up.
When buying for SMG use I consider all off brand the same garbage as aluminum case.
FYI- Maxxtech 9mm brass has an internally stepped case. Total garbage. Will separate.
“bullet” rollmark lowers in general are scarce compared to the regular M4. Factory SBR with that is pretty cool. Typical price considering new-style fake government property 16” guns are sometime $2500
or more.
Remove the magazine release from the gun. Inspect the ledge/edge that locks the mag from falling. You may find its rounded over instead of sharp. If so, use a file or grinder minimally to create a sharp edge without losing much material which can cause the mag to sit in the gun slightly lower...
^ yes I’ve been treated poorly too when trying to help with descriptions, etc.
I think, okay, fine, good luck with that. ✌️
In a case like this where the guy may have zero clue his life may change drastically I make the effort regardless.
I like the C a bit more than the K due to length of pull.
I wouldn’t want an A as I prefer compact in the front end.
All my rifles are SBRs and my only 12gauge has a 7” barrel… so obviously I went for the shorter 31c
I‘ve shot the 31k & 31c literally at the same time.
Correct the 31c has a 2” hard plastic spacer so the stroke is the same is the 31k.
The guide rod and ejector is longer on the 31c vs 31k.
K & C
Dual weild. The C was a touch faster as I was using additional spacers speeding it up to 850...
