I just bought a 3.5" long piece of aluminum Picatinny rail at the SHOT Show but don't need it. $20 shipped in the lower 48.
*SOLD*I also have a sling swivel stud that mounts through the holes in the bottom of a standard handguard. I used this to connect a Harris bipod to my AR but don't use this anymore. $10 shipped in the lower 48.*SOLD*
BOTH ITEMS SOLD
