^^ Sounds like a plan. ^^ please don't!
Looks nothing like a M110 SASS. M16 ris on your pimp drawing when a M110 takes a KAC RAS. I'm sure it's common knowledge that in the real gun (RIFLE!) world that a M110 is a 7.62 and Mk12's are 5.56, a smaller NATO round. The KWA SR12 was modeled a bit after a Mk12. For the love of....I really don't need the spec difference between a Mk12 and SR12. FULLY aware.
Not trying to be being mean about this, but you say you want a M110 SASS styled set up. I realize exact specs are probably not crucial and that you just want the over all look and feel of a M110. I fully understand you there, because I'm in your shoes. LOL.
I could easily tell you all the headaches and issues you will have along the way. It all depends on what you want to experience. I learned a lot from it all. Plus I have 2 large boxes full of parts & three lure boxes with mech box parts & "upgrades". I hang on to stuff in case a gun comes along and a part I have on hand ends up working out.
I spent my first few years in airsoft fighting with guns, issues, upgrading multiple brands etc. What I got out of it was an education and empty wallet (figure of speech). I saw a 2008 KWA out shoot
multiple high dollar DMR's and that's was my introduction to KWA's. Then when their new 2009 line up came out, I with out hesitation purchase a SR10. It has not failed me yet. The only issue it's had was a worn out piston o ring after 14 months of nearly every weekend play.
Flippin, I'm not real sure of your over all experiences in airsoft. Not sure if a complex DMR build is right for you or not. Not insulting you, or saying you can't handle a DMR. Nor the things that inherently come along with a complex build, or an upgraded AEG. It can be a fun experience with upfront success or very frustrating and in the end, you are still sitting home with a non-working gun. I've seen more people frustrated with non-working guns than upfront success.
For a DMR build, tolerances and specs make the gun. In my home office I have a Classic Army, G&P's, G&G's, and KWA's scattered about, and lining up the walls. KWA hands down are the best built. G&G seems like some models of theirs out shine other models. I spent the last 2 weeks teching a G&G M733 to shoot and be able to hit a target at 190ft. My G&G M14 is outstanding, but even that has some quality (material wise) issues. I just say outstanding because of internal specs and solid hop up & barrel fit. My G&P's failed me during and before BIG games. I nearly threw them in a dumpster. After going through two or three "techs" and still having issues I figured them out on my own and now one of them gets molested at every game I go to.
My Classic Army was pretty nice left stock. Then I put new bushings in and new wiring and it got better. Everything was great when I left it at 350fps. Once I tried upgraded the internals I ran into all sorts of compatibility issues. I got it shooting now. Just was not the experience I was planning on.
*Those AIM gearboxes. I would highly recommend staying clear of them.
google "why I hate AIM boxes" I have nothing to do with the site, nor did not write what was on it.
I just laughed when I read it, because I could relate. Two other locals installed AIM mech boxes into their "awesome" DMR guns and their guns still sit in their garages - non working.
I've owned JG's, ECHO1's, a TM...I know JG's and ECHO's have made improvements over the years.
I still think some of their models have a toy like feel to them though. Yeah we're shooting bb guns. TM's just aren't what they use to be.
ICS - I have seen an ICS M16 shoot very well. I know 6 plus locals have ICS's. One guy is a tech.
My experience has been when they upgrade them, something always seems to fail. Those guys are usually the ones walking out in the middle of a game saying their gun just went down. The tech with the ICS. His gun seems to be always working. It's accurate, but just doesn't seem to have the range my KWA's have. Both near the same FPS. There's a lot I like about ICS's, just going off my experiences first hand - what I witness and deal with. The guy's with ICS's will still try to sell a new guy at the field on getting an ICS while they are working on their guns to get them working again.
Cracks me up every time!
A couple KWA custom builds.
some internal work and external parts.
KM4 ris (SOPMOD build)
A beauty I built (wish I owned!)
internal & external upgrades
KM4 originally (URX) modeled to reassemble a SR25 carbine
technically a SR15
That's two out of the many KWA's I've worked on.
People can dislike KWA's. I'm ok with that. Means less KWA's shooting back at me on the field.
