[QUOTE="Sully2, post: 1042915, member: 31820"] Its not any sort of deal at all. I had the wife sit here last night and do my calculations (I had a LG glass of chocolate milk to drink....:) ) and a 5" AL rail from the temp of 32F to 150F ( figured that was about the limits upper and lower) of growth was .00015 and that the difference between steel of a receiver in the same temp extremes and the Al rail was .000046...soooo the growth difference dont amount to jack squat (Wife is a metallurgical engineer) [/QUOTE]
