Just my .02 here so take it with a grain of salt.
First, I have an ASA 20" upper that I am pleased with.
But I'd say that I am the exception, not the rule.
The majority of people here will tell you that ASAS's are more trouble than they are worth. The owner is extremely pissy with anyone who has a problem or malfunction with one of his rifles.
Have you read up on the comments from the ASA forum?
Bushies are very nice for the $.
Gunsmoke Enterprises is a good place to look for prices on those and Kit rifles.
The LEGP Rock River Rifle seams to be an excellant deal. If you don't mind waiting for 3+ months(or more) to receive it.
But keep in mind that these are individually built hand assembled rifles. And the people who have received theirs have had some rave reviews.
FWIW,
Wilson Combat sells their hand built rifles for around $1500+-.
Personally I would not sell your AK, especially if it is an accurate one.
Yes there is a financing option through G&B and 1 other person here. RRA rifle is $660 delivered, but you will need some sort of sight to go on it, as it is a flat top upper.
Chrome lining is for reliabillity and corrosion resistance. And longevity too.
But not as accurate as a non chrome lined.
If you clean after shooting and don't live in a area with Salty air there shouldn't be a problem for which you'd need the C.L.
Some just prefer it on their SHTF rifle for utmost reliabillity.
What are your shooting plans?
What dist. do you plan to shoot at.
Are you just a plinker or do you plan to shoot competitively or burn large quantities of ammo monthly?
Oh, and welcome to the site.
There are plenty here who will gladly offer their 2 cents. Just remember everyone has "Their" opinion. Some more so than others.
My suggestion is to do as much reading of posts as you can.
Use the search feature for specific questions.
Many times those same questions have been asked several times before. And you will most likely be able to answer most of them by yourself.
Good luck,
Del.
