3) PTR91 factory US-made lower receiver with selector. $60 shipped. ** SPF to ott1 **
4) US-made HK21e buttpad from HKParts. $35 shipped. ** SPF to ott1 **
$315 shipped for both Sig 551 items together. $75 shipped for both HK items together. Trades for AR mags, AK mags, M&P9 mags, and CZ 75 SP-01 mags considered.
