The swiss arms looks great, but the price turned me off at the time. Does not mean I still wont buy one when funds allow in the future. I love all types of guns. I do have an XCR and have not had any problems with it that were not c-Prod mag related. I have never even used loc tite just made sure all the bolts were tight. Its a great gun, mine was bought this year and is probably a newer model. I heard the earlier ones had issues though. so far so good for mine. Mag availability is maybe an issue with the SAN(dont know how widely available they are), compared to the XCR. Plus the XCR will take most AR accesories(grips,etc). Either way i still want both, and a tavor, and a m14 and etc.. they are all unique. I am a Gunnut and want them all.
