Q: Does this adapter affect accuracy or reliability?
A: No. The Gen4 adapter is engineered to maintain full function, zero POI shift, and reliability when deployed or folded.
Q: Can I fire my AR with the stock folded?
A: No. Firing with the stock folded is not recommended. The rifle must be in its open, locked position for safe operation.
Q: Will it work with my pistol-caliber AR-9?
A: Yes! The Gen4 is fully compatible with 9mm AR-style PCCs.
Q: How does this compare to Law Tactical?
A: The Gen4 is lighter, more affordable, and includes a buffer extension — making it a strong competitor for AR builders seeking premium function at better value.
