One more change ... I'm almost done - OOW BAR


Recommended Posts

Still looks very nice . Still say replace the gas regulator before bluing . :wub:

Checking today to verify that the early regulator will work with the OOW rifle without modification being necessary to the rifle itself ,,, Up to now all I have done are cosmetic changes ... I don't want to end up with functional problems.

I talked with the gentleman at BMG parts this morning and he advised that the OOW rifle would require modification to work with an early GI regulator. I have a $4300 rifle that I have put around another grand into with new wood, sight, flash hider, and butt plate. ( I am not even figuring in our shop time) and I really don't want to get into making changes that I am not comfortable with making. I might paint the later regulator gray, but for now I am content with what I have ... At least it's 4 pounds lighter.

I also talked to the gentleman at BMGparts.com about using the early style gas regulator on my OOW A3. He said that the threads are the same, so no mods there. He seemed leery about me modifying the gas holes in the regulator itself, but I got the details on how to modify them from emmagee1917 (Chris). Chris said no mods are required to the A3 gas tube itself... only enlarge the gas ports on the regulator. He gave me the sizes if you want them.

 

I went ahead and ordered the early style reg from BMGparts.com but the gentleman told me that it is not a true WW1 style regulator but an early style A2 regulator. He said they have not seen the WW1 regulators in a long time. But... this early A2 regulator looks very similar to the WW1 (more so than the shiny A3). So... after I get it, I will see if it is a true swap out before I actually modify it.

Thanks ... Could you email those specs to my son? As long as I don't have to change my rifle itself I would like to give it a try.

OOW used to have the older styles in stock . They just drilled them out as they had to do on the A3s and put them on . You really have to have the rifle in your hands close to see the difference . The big hole in the A3 just draws your eye to it .

Making your own can allow a degree of customization to your gun . If left original , the small port would make it a single shot . Drilling it out to a little small than OOW specs would allow moose loads without straining the gas system . Your goal otherwise is to have #1 work with a used , worn in , clean , well lubed gun . #2 would be for a new non-broken-in but clean and lubed gun at first but then for a used , broken in gun with minimal lube , dirty , or weak ammo . #3 would prob'ly never be used as you won't mistreat it like a war gun would be , but it is there in case of lack of lube or weak ammo .

It needs more gas than a GI in order to provide energy to cock the hammer that the GI gun does not have .

I have had several of the OOW semi BARs, and still have one left (marked R/O - receiver only - with a serial number, as OOW used one of my old parts kits to put it together for me) and from the first one (serial No. 54; bought in 1996 I think) to the last one I have always been able to get them to work on the large gas setting on the GI gas regulator when new. Later on, after about 100-200 rounds, they would work on the middle setting without drilling the holes out. I think the”break-in” period was due to the fresh Parkerizing and after some “smoothing out” through firing the gun works well enough if using good GI power loads. Might try a regular gas regulator to see if it will work. If it will not, you haven’t lost anything but a little time.

Chris... I just received my "early style" A2 gas regulator from BMGparts. I notice that it has four holes. Three small holes on the perimeter and one small hole in the large recessed hole in the end. Did the early M1918 WW1 gas regulators have solid front ends? If the regulator that you modified only had three holes, then I'm afraid your specific mods won't work on my 4-hole regulator?

No problem , you don't know me from Adam . I believe the regulator I had was the one with the vent hole on the end . If you're hesitant about the modification , then do the following . First ,I would also check how the current functioning one's holes compare to my dimensions and the one you bought and compare the current functioning holes to the drill bits . Next , I would try it in your gun unmodified . If it does not operate on the smallest , then try the middle , if still no go try the largest . If still no go , well , because the smallest enlarged hole is still larger than the largest unmodified hole , just drill the old maximum to the smallest enlarge dimension and try it . If it does not go , then open it up to the middle enlarge dimension . At this point it should be working or at least trying to work . If not , recheck your lubing and cleanness , If still not working , open it up to the maximum size . It should definingly work then . You might be able to cut out some steps by your comparison with the working regulator .

Just go slow , the result will be worth the time .
