These are the 10-round mag inserts for the Army M261 .22lr conversion kits for the AR. They are used, but in excellent condition. Price is $13 each, plus exact shipping cost by an insured verified delivery method of your choice.
I also offer 30-rnd GI mags for $5 each. They are 0-5% finish, with no mechanical defects. They would be perfect for dedicated use with the M261 mag inserts.
