I have recently purchased an HK SL8-4 and also bought an AR-15 magazine well conversion kit for it. When I put the original next to the new mag well they appear to be the same but when I try to install the new one the hole for the retaining pin is off about 1mm and its a very tight fit so there isnt any movement to line them up. Has anyone else had an issue with doing this conversion or am I missing something?
