I'm looking for a Euro SP5K with the proof stamps on top near the serial number (not the latest batch from Arms Unlimited that has them on the trigger housing). This SP5K will be cut up for a build so it doesn't have to be new but the receiver needs to be in good/excellent condition. Please email me at [email protected] if you have one and would be willing to sell it at a reasonable price (close to the $3k price that AU was asking). Thanks.WTB: Euro SP5K for build project (NOT one w/proof stamps on trigger housing).-20180525_203117.jpg
