Parts interchangeability

[Marcos]

Gents. Cruised old posts but couldn't find the answer.   How interchangeable are the internal parts between older and newer H&R and NEF firearms? Could older non transfer bar parts be fitted in to a newer model ??  I can cheaply pick up a number of old/new junker H&Rs for parts but don't know if it is worth my while.  What do you think ??

I think JB has sucessfully installed the older low profile hammer on late model frames.

I'm not sure about the older parts, but between the SB-1 and SB-2 I have had no problems so far.
I have switched hammers, triggers, and triggerguards, without a hitch....though the transfer bar I have not tried yet. Just FYI

For current production SS1-SB1-SB2 frames, made since 1987, all the frame parts are the same, the parts list only shows one hammer, trigger, each type of spring, etc.... all the internals of the frame are the same. Ejectors changed in '99, different part numbers for ejectors in firearms made prior to '99 for each caliber.

Tim hoe doe we know the approx age of a barrel if no frame. Have 223 2 barrels say SB2 one does not. Going to have this one reamed to a (no sb2) to a 225 winchester, found a local to do it short TAT
Need a new ejector is it old or new style. How can we tell,  do you have pics of both to compair with

According to someone at H&R, there are 4 difference thicknesses of the ejector posts, but I've only noticed 2, and Brownell's only lists 2, post '98 and '87 to '97, the older ones are the thick ones which are about .180" thick and require a deeper cut out in the bottom of the breech face, newer ones are about .120" thick.

Thanks Tim, Would a 30-30 extractor work for a 225 winchester (from a 223) , Cannot get into most sights here they Are blocked & would like to order parts now if needed
Thanks again

I would use a .30-06 ejector, the rim of the 225 Win is the same diameter at .473", you'd need to remove the lifter button from the .223 barrel since it's needed for rimless cartridges, but not rimmed.

I would look closely at the dimensions of the 225 Win and compare it to the 30-30 and the 30.06.  I think the only real difference at the base of the 30-30 and the 225 Win is the diameter of the rim, whereas the 30.06 has a larger diameter body.  The 225 Win rim is the same as the 30.06 family so that the same bolt face could be used, reducing the machining required to use the 30-30 case size.  The rim is larger on the 30-30.  Dimensions can be found at reloadbench.com and steves pages.

Bolt face?? What's a bolt face??? Neal, this is the NEF/H&R forum!!

Bolt? ............isn't that the thing that holds my gate closed?

Tim and Marcos, I would suggest you do not remove the ejector lifter button if the ejector you be using is one from a rimless caliber (30-06) Only remove the lifter button if you are using an ejector from a rimmed cartridge, as a 30-30 or a .357.
Also Marcos when dealing with these H&R's be careful when ordering parts referred to as "ejectors" or as you incorrectly called the part, an "extractor", the companay now uses both depending on the year of the barrel and other vagueries and may send you an "extractor" instead of and "ejector" and it will not work correctly or be the same dimensions..I know since I am in the middle af a project right now, a former .22 Hornet (rimmed) that is now a .223 Remington (rimless) that may become a .22-250 (rimless)....<><....

P.S. - smokinjoe5150, I think it is a latch that keeps your gate closed, and H&R's have latches!!!
