The only negative with the conversion is that you only get trigger time. Most of the other controls do not work the same so you will not be trained on the use of the controls. Point of impact can be set identical at training distance of your range set.
Also the lack of a backup rifle for the event of a part breakage is another overlooked bonus. It will be that funsaver of the weekend, lifesaver of the hypothetical catastrophe. <------- thank you spell check
