922r and the CA-94 std

[viper5194]

Anyone have an accurate idea what US parts are used in the newer Coharie CA-94 std models? Im thinking the majority of the parts are US, but the included manual doesnt say, and TB will not respond to emails it seems. Just wanting to make sure the parts count is in check when I go swapping parts. As far as I can tell so far :

US made reciever

US made bolt ( want to add HK bolt or RCM bolt )

US made carrier ( plan on adding RCM carrier )

US made recoil assembly

US made lower ( im certain the internals are HK but not sure if its all or some parts " Metal box" ) I can always add PTR parts if needed to count towards 922r if I have to right?

US made barrel

US made handguard ( looking for a nice used Surefire M63 to count as US part )

US made stock ( swapped with POF A3 from RTG )

US made mag ( want to use HK mags )

US made cocking support and handle ( adding HK cocking suppoert and MP5 handle )

US made trunion

Is it safe to add an mp5 hk made mag catch?



Also curious to know if adding stuff like HK springs, firing pin, extractor, ejector and such count toward 922r parts or are those just misc items ?

BTW: This one runs like a top. Bolt gap was right at .018 with stnd rollers so the barrel was pressed right. Reciever seems to be bent and welded up right, A3 POF stock went on with no force. fits like a glove. sights are not canted at all, welds looks great. Strong extractor, round will not fall out when placed in bolt head and shaken vigorously. Im just not happy with having a MIM bolt, plastic cocking support, crappy molded cocking handle, furnature with all kinds of flashing still attached from the molding process, a cast carrier , who knows if its even the right weight since it likely doesnt have the tungsten added. Oh and the .223 or .308 hammer spring is going by by soon enough.

Whoa, calm down big guy. Most of the stuff that you're talking about isn't that big of a deal. I'd just change things like the cocking support. The handle that came on mine is identical to an actual HK. You can trim the furniture if it's not cracking or breaking apart. Also, the SA carriers don't typically come with the tungsten fill. I think that's an addition for running FA, as it keeps the bolt from bouncing.

I'd suggest just doing little upgrades on certain parts that need it. Sounds like you got a good one and you should focus on buying ammunition now. :D

Oh, and post some damn pictures!!!

Dont get me wrong, I like the gun, im just picky. If you could see my AR's youd understand. I like my firearms to be perfect, fit, finish, and function. This CA94 may be a Coharie, but it will run like a perfect MP5/HK94 semi or I wont have it. As it is, it runs fine but subgrade parts fail quicker than correct spec parts. I figure if I have less than 3k in it when im done, and its the way I want it, and runs 100% reliably im gona be happy. Just the way I am. Ive never been a fan of MIM or cast parts so those will be the first to go even if I cant get HK stuff, RCM parts will make me happy.

Cocking support is incoming with an HK handle. The one you have may look good, the one on mine looks as though the mold process failed and its dimpled on two sides. The stock has already been swapped to the A3 POF and im a fan of rails, so the HG will be going away for a Surefire setup with knights panels and probably some type of light. Ordering a sling in a minute from Specter. The 3 point CQB setup they have looks slick.

Cant say im unhappy, just like reliability and have heard stories of guys running 400-1000 rounds through one and then having a failure. If it runs 100% now and the bolt gap is in spec which it is. Replacing the items with better parts should only fix the reliability and not affect function in any way, at least thats my thought process.





And pics of my other toys just for show...

please please please SBR it (move if you have to!)

1. Get rid of that comedicly long barrel
2. Swap in all the genuine H&K parts you want. Once you sbr you dont have to conform to 922r.

Once you sbr you dont have to conform to 922r.

you sure about that? Do you have a source?

If it's a pistol first, and you SBR it... maybe...

But, in this case, the guy is going to SBR a rifle. I'm concerned that he would still be covered by 922r. Hmmm....

edit:

(you know, I'm just really not sure - I've read conflicting "opinions" on this.)

edit again:

now that I'm thinking about it, I've run across several individuals who talk about ATF tech branch sending out letter(s) to people telling them that an SBR IS subject to 922r, if you SBR a rifle (not if it is a pistol first)

But, then again, I think there have been letter(s) from the ATF to the contrary.

My opinion - don't get so damn caught up in if the parts are HK or not. Cocking tube support - fine. Mags - fine. But a lot of the other crap doesn't really matter....

Not worried so much as to if they are HK parts or not, im just not liking the cast and mim parts. As of now the parts I have or have incoming are:

replaced stock with POF A3 ( Have )

replacing .308 hammer spring with the correct 9mm spring ( Incoming )

replacing the Coharie HG with a Surefire M63 ( Incoming )

replaced the plastic Coharie cocking handle and support with HK Metal cocking handle and correct MP5 metal support ( Have and installed, Thanks to member Turnfab for the help locating parts at great price )

replacing the MIM'd Coharie bolt with a ID coded MP5 bolt ( Incoming , found one for $225 like new and with partial trade of AR parts cost me $125 cash in the end )

The last items on my list are a Specter CQB 3 point sling ( cant decide which color ) , and a MP5 carrier from RIM once I get the $150 spending cash restored. and im done... I THINK!


Should be bullet proof when im done, thats how I like my firearms..

As sure as you can ever be when dealing with the BATFE:

http://www.cs.cmu.edu/afs/cs/user/wb...tf_letter3.txt

However, the Bureau has previously determined that the lawful
making of an NFA weapon would not violate Section 922(r), since the
section only addresses the assembly of "nonsporting" firearms, and
not the making of NFA weapons. Therefore, the lawful making of a
short barreled rifle would not be precluded by Section 922(r).

The response refers specifically to an FN/FAL rifle assembled from British parts.

I'm just curious how many inches is that barrel sticking out from the gun,,maybe you can put barrel shroud on it to look more like the familiar mp5.
