I have 1500-2000 rounds of 7.62x51 to trade for 5.56.
I find myself at the range with the M4 variants more than the FALS, M1-As, Fr-8s, etc and I am looking for a trade. I have SA, Santa B, Port, Radway and Malaysian to trade as well as Aussie F4. The Aussie and Radway are pristine and carry a higher value. Tracers & AP are also available. All ammo is original surplus, no reloads. Some are linked (Malay, Radway, SB) and others are in clips or boxed (Radway & Aussie) and the SA is boxed and/or battle-packed.
Make me an offer. I am 15 miles North of NYC in Westchester and am often at Calverton.
