Lone Wolf SS Barrel with custom engravings for Glock 36, DPMS Systems SS RSA with two separate springs for Glock 36, Tungsten RSA for Glock 36. All in great shape & lovingly maintained. I'll take $150.00/shipped for the lot. I like using PayPal for payments & I'll ship UPS/tracking once payment has cleared. Please email me at: [email protected]. I'll also check back here, once a day, for the first ten days to answer any questions. Cheers!
