Want to Sell Billet Rifle Systems BRS47

Billet AR-47 receiver set made by Billet Rifle Systems. Lower is an 80%, it'll ship right to your door (or wherever else you may want it). Upper is a side-charger, which should be a bit handier since you lose the LRBHO with the AK mags. I also special ordered it without the forward assist. The baggie of small parts has the mag catch assembly, a tension screw to take out any play between the receivers (bit redundant since the machining on them is pretty tight), and a special cam pin to work with the side charging handle. I have just over $550 into it. Open to offers. Will trade (+/-) for an SKS, stamped M70 parts kit, Tantal parts kit, vz. 58 parts kit, PPSh parts kit...
