I have seen a couple lately for about 4 bills. IMHO, the Lipseys special Buckmarks barrels are too long to keep HV 22LR subsonic. If they had done a 4.5 inch barrel, to me that would have been ideal. Then you could shoot the cheaper HV and it would stay subsonic. Keep your Rugers and by a Tactical Solutions upper for one of the them. Lots of different configurations to choose from and they are accurate and run great.
