I recently got a 500 magnum, and want to make it look absurd. I found a company that makes threaded inserts that replace the factory comp. Since very little aftermarket comps are made for the 500 mag (ive seen just 1 that costs over $500) i want to know my options. After comparing diameter of the 500 S&W with other .50's I found that the 50 Beawolf and 50 AE all have the same diameter bullet and should work. 50 bmg and 50 linbaugh comps will NOT work as they are technically 51 caliber. Is there any issue in using a beawolf or 50 AE comp on this? Are there any other 50 cal comps that will fit the diameter of the 500 S&W

I know this is not "practical" i just want something that looks like a crazy space pirates blunderbuss.
