I have the following US Made parts for HK91/PTR91/G3/Cetme/SAR3/SAR8 .308 rifles. The prices are local FTF but I will ship also for an additional shipping charge (happy to ship it all for one $10 flat fee).
1) Bell & Carlson made thumbhole Buttstock/Pistol grip assembly complete as it came off of my Springfield Armory SAR-8. Complete assembly ready to put on your gun. This would count as 2 US parts for 922 compliance. $45.
2) HK91/G3 muzzle brake complete with retaining ring. Stamped on the muzzle end of the brake "Made in USA". This would count as one US part for 922 compliance. $20
3) HK91/G3 thin forend, black. "C" stamped on the inside (Century) - does not have a heat shield liner. This would count as one US part for 922 compliance. $20
4) HK91/G3 Black Pistol Grip. "C" stamped on the inside (Century). For use on the steel trigger housing (but cannot be used with above Bell & Carlson thumbhole stock assembly). This would count as one US part for 922 compliance. $15
First to say they take it, gets it. I do have them cross listed. Either a PM or an email - firstname.lastname@example.org
will work to reach me. I will be happy to do a FTF in the North Dallas area (I am in Plano). The above prices do NOT include shipping, as indicated would be happy to ship it all for $10. Either a USPS Postal Money Order or discrete PayPal gift payment will work.
