I would agree with Steve on this .
Its sad really that parts have become such a cost . But when you really look at it I guess , the cost is still pretty reasonable .
Take casting a trigger guard for instance .
When I cast a new guard I have at least 2 hours in it . Ranging from laying up the mold , pounding the sand . Melting the metals . Not to mention I have the cost of the gas for my foundry , the brass as well as maintaining my crucibles which don’t last to long .
Then you still have to clean things up to make it suitable for use . I simply cant do that process for the cost charge to simply buy that part through a supplier.
BUT on the bright side those suppliers most times don’t offer the parts I want .
There simply is no replacement for quality work .
Now unlike steve , I do rework production guns of a lot of different qualities but I also let folks know that those rifles will never be the quality of a good quality rifle made from good quality parts . Sure it may shoot and shoot well and serve their intended purpose BUT

Now I have and im sure others here to include steve have been know to say here , try this I think you will like it better . Try it , this is why I recommend what I do .
Some time back a member of our organization wanted a new lock for a rifle they were building ..
They contacted me to see if I had an old factory flintlock laying around .
I did but IMO it wasn’t satisfactory and never was , even when new .
The person felt he simply couldn’t afford a quality lock . So we did some trading and I agreed to send him the old production lock .
Well once I got the items we had agreed upon , IMO they were worth more to me then what that old production lock was . So I simply boxed up one of my good locks and sent it off .
When that fella got the lock , his remarks were something to the effect of , I have never seen a flintlock that sparked so well , its like its on steroids or something .
Well that lock wasn’t what I would have considered a top of the line lock . It was just a simple L&R medium quality lock . But comparing that part alone to the production lock ,

?? Well enough said .
Now that’s just one part , taken as a whole the end reliability alone is IMO much greater with good quality parts found in custom rifles .
So I would say this . Buy you a parts kit from one of the manufactures . Get a couple building books , read them . Your not going to be into things more then a couple hundred more then a descent production gun and in some cases less the what you would pay for a Pedersoli at cabalas.
Build your own rifle , we will help you through the steps and answer any questions you have . don’t rush , take your time . The end result will be that you have a rifle that you built with your own two hands . A rifle that you can pass down . A rifle that will in the end be worth all the knowledge you put into learning to build it ..
Not to mention when you use it for hunting the pride in taking that first deer or what have you with a rifle you built will be worth way more then the price of the parts .
