Sorry Ragincajun, I missed the "medium heavy" part.Well, I want a better quality barrel than the Springfield armory, and possibly a medium heavy barrel, so I'd be switching barrels regardless
I suggest to get the the medium weight no questions ask.......but if need to know.........revert back to post #8.GI2So currently my spare M1A has a full length barrel and I'm considering switching it to an 18". Now, should I get medium weight or normal profile? I use it mainly as a range toy.
Cryo is where the barrel is frozen to stress relieve it which increases cold to hot barrel shot accuracy/consistency.They do offer CRYO and M80HT, whatever that is...
Thank you for that information.Cryo is where the barrel is frozen to stress relieve it which increases cold to hot barrel shot accuracy/consistency.
M80HT is their fancy term for Melonite treatment. It's a treatment that brings carbon to the surface making metal (including stainless steel) have a black finish as well as increasing the surface hardness. The process involves dipping the parts into a hot salt bath (temperature dependent on desired results, some reaching 1200 degrees F). The carbon surface is also more corrosion resistant and very slick having a semi-self lubricating effect.
For me, I wanted a heavy-er barrel (in this case, modified medium) so that POI would not shift too much as the barrel heated up. The chrome will also help when the throat gets real hot (if i ever wanted to shoot a lot in succession) in preventing accelerated barrel wear.im not sure why someone would want a heavy barrel that is chrome lined. it kind of defeats the purpose if you ask me.
