About 2 weeks ago I ordered a 57SML sight for my Renegade from Opticsplanet.com. Nothing against them because I've bought a lot of stuff from them with great pricing and service. But after I placed the order I received a notice that the item was on backorder! It would have been nice if they would have told me that at time of order. Will Being the impatient person I am, I called Cheaperthandirt and they had them in stock. So I ordered one and then canceled my opticsplanet order. Hopefully I will have my sight by the weekend so I can sight in my new GM LRH .50 caliber flintlock barrel.
