I'm looking for a scope mount for my Springfield M1ASpringfield offers two different Generation 4 mountsone steel and one aluminumThey are not the same design executed in different metalsthey are differentThe steel variety goes for close to $300.00 and the aluminum goes for about $150.00Their website offers little to no description of either mount.Does anyone have an experience scoping the M1A? What are the pros and cons of these two mounts? Does anyone else offer a scope mounting system for this rifle?It seems counter-intuitive to bolt a piece of aluminum against a piece of steel and leave it there for long periods of timedoesn't it?I don't want to break the bank but I would like an accurate, reliable mountAny information would be appreciated as there are few subjects I know less about.
depending on where you live,if possible,r30 fiberglass or blown in either is the standard around here,and,for sure never block your ventilation,you need the air in your attic,freezing cold attics don't make you cold if you're properly insulated
You mean the insulation that you put in your attic or crawlspace? That fiberglass stuff works pretty good- just roll it on out- the thicker it is the higher the R factorJust remember to not reduce the air circulation especially around eaves, or you'll get condensation.
The best insulation that you will find is R15 fiberglass that is installed inside the attic between the roofing raftersIt's twice as thick as R12 which goes behind wall panelingIf you're talking about roofing shingles, they don't really act as insulation but architect shingles last the longest.
I have never heard of aluminum insulation and I don;t think it would work very wellHot and cold flow along metal very quicklyUp here in Canada our code calls for R40 minimumThat's 12 inches of insulationYou can use 2 R20's and get the sameThe R15 the guy spoke of above this is not twice as thinck as R12R20 is almost twice as thickBlown in is the best specially after all the work is doneIf you try and put batts up there after it's a pain in you youknowwhat.
All Springfield's mounts through Gen 3 have been very poor designsI haven't heard any word on the Gen 4 though, it looks betterI own a Sadlak steel ($250) and it's perfectHighly recommended for a Springfield M1aThey make a Aluminum style for about $100 lessAlso look into Basset, ARMS, etcI hear good things.
