Part #66 for KSC MK23
 

Well this part is sold out almost everywhere i look. Specifically this item with the reinforced sear pin. The reason why this item is so important is that through my research, i have found that this is a very problematic part for the MK23 series. So, when i found a reinforced version on UNcompany, i hit the ceiling. Now that being said, my question is why is the reinforced version made by KM, which costs only $12.00 US cheaper than the KSC replacement part, which costs $15.00 US. is KM a lesser quality company? through reading reviews and such, i have not read anything to suggest that KM is a bad company, or made shoddy parts. Needless to say, i wont have to settle for the TM MK23 when summer comes buy, but rather the KSC MK23 (i was going to get the TM version if a replacement Part #66 could not be easily obtained). What are your opinions on the Part #66 that i mentioned above?

Best regards,

Forget the MK23. It's a dead platform. Discontinued parts left and right.

why forget it? many reviews, and ASC members, said that with the right upgrades, it is a beast of a gun. Even stalker said with the right upgrades and BB's his pistol can shoot farther than some AEG's (if remember correctly). All i really have to replace is Part #66 and the recoil spring and it becomes a great gun. Throw on a metal slide, 380fps kit and a TB inner barrel, hell it would be shooting better than a stock TM M14. if you dont mind me asking kos, do you have any experience with the gun, because i am always willing to learn more about the gun.

That was with my M23 in stock form using propane and 0.28g Bastards. Easy 150ft out of it.

As for ability to find replacement parts, UNC has a pile of the stock parts.

BTW, read my review on airsoftparts.com under the Airsoft Surgeon 380 kit (http://www.airsoftparts.ca/store2/in...reviews_id=22). I think it might only be useful in warm weather, but in my basement my fps went from 315fps down to 280fps.

If you want something reliable and free of problems, stay away from the MK23. I have one and love it but it is a pain in the ass & wallet. Unless you buy every upgrade part thats out there for it, it will constantly piss you off, and even then-no guarantees. It's also a big chunk to have on your hip as a back-up, it's actually the same size as a TM D.Eagle. If you really love the gun for no other reason than it looks & feels cool it's your money.

unfortunately the link wont work for me. i always have trouble with connecting to that site. always says it can't find the server. but that is an interesting point. did you replace the recoil spring? and how is your sear pin (part #66) holding up?

Mine serves me well and is easy to carry. Heck, I also bought a TM Mk23 springer to use in cooler weather. Mine hasn't been a pain in the butt at all, my KSC M11A1 on the other hand.............

well after playing COD4, i am starting to fall i love with the USP .45
are there any kits that allow you to upgrade the USP's fps. so far all i have found it an upgraded recoil and hammer spring set.

Yes. This is exactly why I have a grudge against it. It's an awesome piece (especially if you have an HW/HK;)) , just ... doesn't have anything going for it upgrade, and reliability wise.

Out of the 5 or 6 WA 1911s I've owned, ZERO have given me troubles, and all have been 150% easier to find parts for (slides, frames, sights, triggers, etc) ...

Recoil spring was the first piece I replaced, and it's shit. I'll C&P the review here for you.

Oh ya, part #66 has no issues in mine, and I got it third hand used, and so far I must have shot at least 2000rds through it since I got it last July.

thanks for the info stalker. i plan on order the HK HW version from 007. ill replace the recoil spring for sure and part #66 just cause every other review i have read said its problematic. however, that 380 fps kit is now giving me some movie after reading your review. Still, i love the gun and as a sidearm, i should think that it kicks major ass, esp for a sniper/DMR, which is the role im going to start out as (DMR that is, sniper later).

I have a KSC USP 45' (Japan model) and it's a totally different story. Metal slide and a KA recoil spring and a high flow valve in the mag are the only upgrades I've done to it and it was pushing 390fps on a hot summer day, On cooler days around 320-340fps. I've lost count of how many rounds I've put through it and It hasn't given me a single problem. As with all USP models I never use the double action trigger pull, I only fire it with the hammer back as they are known to have the triggers break ( mostly on USP compacts). I don't know about the other models but I would highly recomend the KSC Japanese model.

good to know, ill keep that in mind. knowing me, down the road ill just end up getting both pistols.

Another thing to note about the MK23 is if is very sloppy slide/mag wobbles, but the USP feels nice & tight.

I rearranged my recoil spring assembly (is the dual spring one) and I have the slide running halfway, good kick and fast action, not breakage or sluggishness anymore. Past few games I've carried my MK23 on my left side in drop leg, and my G19 right side. Have also carried my MK23 in the long side pouch of my Eagle chest rig. Never seems to be in the way though. Right side G19 is for quick drawing for fast defensive response (like under fire while lying on back and get a gun hit, yes, happened a couple games ago, was Helios firing at me with his G36 and I was Glocking at his ass through brush, both of us hit each other same time. Lol), left side MK23 is for 'secondary primary' use, with or without suppressor (incidentally, mine is much more accurate witht e suppressor on, and it's only got 1/4" open cell foam in it).

And ya, primary is always an MP5, and I lug my CA M24 on my back 90% of the time when playing.

BTW, the KSC USP full size with metal slide kit is damned sexy (USP Compact I've never liked)! Korv sent me his to fix three of his mags, I loved the gun, was like a smaller version of the MK23 and man did it shoot and kick hard!! Accuracy sucked, even compared to my MK23 (With suppressor on, double action "quiet mode", I was hitting a plastic coat hanger at 30ft about 3-4 times out of 10 shots).

Mine used to be a charm (HK & HW), the dual recoil system made very smooth ( even with the upgrade spring) got the guarder upgrades ( recoil, hammer spring and reinforced part 66) until the day the piston system broke and now I cant find the parts for it, so I have 2 MK23 prior to 2005 version laying around broken :(

and this is why you get a 1911...or a USP :)

tm p226 ;)

see, back in the day, when i started paintball, i didn't listen to the advice of the vets and i ended up buying an entire platform, just to sell it within 6 months. I dont want that to happen with airsoft. thats why im getting an M14, cause its such a good stock gun (that and i have always loved the M14) and thats why im not going to upgrade it off the bat, cause the FAQ and you guys says i should play stock first, so when it comes time to buy a pistol, i still don't know what to do. this thread has told me both: buy a MK23 and upgrade it, for it will shoot well. or dont buy a MK23, cause its nothing but problems and a waste of money. truth be told, if stalker can get his pre 2005 version to work well, i think i should be able to get a 2005 HK HW version to perform almost flawlessly no?

Honestly no idea, but mine in stock form has performed very well, and still after a tightbore was added. Next I'll get a metal slide kit. But seems like latter MK23s suffer all the issues here, one report in the US was that his spring guide broke in half. Was a shitty pot metal one, not the solid steel one I have.

Smart man. 1911s (specifically the WA variety) will last a fuckin' long time, and wont have stupid problems, that can't be remedied.

can you make a KSC USP shoot as well as the MK23? If so, ill just make the USP .45 from COD4 and get a TM MK23 just so i can say that i have one. still though, i would like a realistic blowback MK23. the reason why i love it so much, other than the fact that the SEALS use one and that in the first Splinter Cells games, you had one is that you can cock the hammer back and fire off a bb without the slide moving, just like the real thing. i think that is one of the coolest features about the gun.

EDIT: any idea on my original post? why is the reingorce sear pin cheaper than the simple replacement one?

SEALs often also use the HK USP Tactical since it's based largely on the MK23, and the MK23 was based largely on the original design of the USP in .45cal. Offers same performance, in a smaller package.

interesting i didn't know that. i personally dont like the look of that though. for me its either the USP .45 or the MK23.

Personally I'd go for the Tactical over the standard USP, I guess simply because of the match trigger and threaded barrel (well, real steel anyways, but I don't think you can get a Tactical airsoft USP unless you add parts.)

actually, you can.... scroll down a bit

just to clarify, the 05 MK23 is the one with the single stage recoil system; that is to say there is a spring guide and one spring, whereas the pre 2005 version are more similar to the real steel gun, with the dual spring, recoil system, as in the version that stalker has. is this correct, or was my research in vain?

EDIT: also, any idea with regards to my first post?

yes thats correct. If you're getting the older dual stage, dont expect lots of recoil since the dual stage takes most of the shock so its more accurate.

Is also a lot sloppier recoil. I'll see about taking a pic of my modified spring guide assembly using the parts it came with, improved the recoil, speeds it up a lot and has lasted a long time sd far.

After freezing my ass off in the basement and having cold hands, AND chronying my 340fps G19 (got in the 260fps range), I'll have to retract my "20-22C" I've been testing the MK23 with the 380 kit with. Will have to wait til summer to see if I can actually get much higher than 315fps (stock). Some of the parts in that kit didn't fit in my MK23, the important ones did though (the rocket valve tube thingy, and it's spring), so we'll have to see.

interesting. i think the 2005 HK HW version will have the flaws of the previous models corrected.

Am sure that model, the newest one, is the one that has the flaws (like the spring guide snapping since it's pot metal), and the 2005 I'm sure has flaws as well. What I've seen among my digging (and experience with my own) is the pre-2005 models are the most robust.

Give this a read:

well unfortunately, 007 and A&A only stock the 2005 version i believe. still, i wonder if i could get a machinist to make a steel spring rod, or hopefully they make a replacement part. i really am at a lost at what to do by the time summer comes and its time for me to purchase a pistol.

The spring guide could be a bit of a job, due to its angles and such at the rear of it (where the barrel cams).

Largely, you want a KSC MK23, buy one. To many people are trying to poopoo on your decision and you are letting them. Biggest complaint I heard before buying mine was the size, and I find it large yes (considering my secondaries before were G19s), but I love it non-the-less and even have a few different options for carry (including a Versapack and an Eagle drop leg). What I said before is that this is a good gun, it's the KSC M11A1 that I have which is a maintainance pig, not the MK23. Other's experience is just that,their own experience. It's largely like the debate about running a KSC pistol with stock slide on propane, some say it breaks within the first couple hndred rounds, others like me have run thousands of rounds through theirs and haven't seen much in the way of wear at all.

In the end, sift through the data given and make your own choice.

thanks for the sound advice. thats just what ive been wanting to hear. i just didn't know it until you said it. i think that i will get the KSC MK23. now i just wish i new why the reinforced part 66 cost more than the stock replacement part off UN company.

As a side note, i think i will start to order KSC parts so that they can't go out of stock on me when the time comes.

Because the reinforced part is reinforced.

i would think that the reinforced part would be more expensive as it would be more durable and made of better materials than the stock part. but hey, what do i know?

i know this is a necropost, but i didn't want to start a new thread for essentially the same topic. Does anyone know if you can put a metal slide on the TM Mk23? And i read b4 in this thread about the piston assembly breaking on the KSC MK23. what are the chances of this happening, or is it just a lemon?
