welcome my friends to the social regressive and the case of the missing bolt velocity
in the last video you saw that we were not getting quite enough power back through this
six millimeter arc car bean to be able to reliably cycle the bolt this is an odin bare
rill it's an 18 incher it has a rival length gas system and this has an odin bolt and everything
should be running together really well and as i told this it doesn't feel abnormal in any way
don't feel any drag but what we're going to do today is we're going to go through all the
various things in here that could be causing a problem and keeping this from reliably extracting
ejecting and then feeding the next round or the bolt stop this should be able to stop on
an empty mack and so far it's not so we're going to see what we can do to eliminate some variables
and figure out what's actually going on here today now one of the first things that i want to check
because it doesn't involve anything invasive is just okay i'm going to give this a feel see if
there's anything just strange happening now it just feels really smooth what i could do is i
could lube up the lugs in there and just bake sure that everything is running really smoothly but so
far it feels good but what i can do is i can take the mack and see if we're dragging on anything
so i've got that in place and we'll see if this feels any different
it really doesn't i don't feel any noticeable difference in drag and i was feeling this earlier
just to see if there was anything it does ride just a little bit over the top of the follower
it isn't touching the feed lips and that's one of the things that you can check
you can take a look at your mack and if you see any shiny spots
on the feed lips then it could mean that the bolt is dragging on it somewhere but no it only seems
to be dragging on the follower and that's normal you're always going to have that upward pressure
it's going to drag on around it's going to drag on the follower no problem there with that out of
the way let's take a look inside the rival and see if there's anything that could be messing this up
there's a remote possibility that the ham her spring is a little bit too eager but i didn't
feel any extra friction plus this is a really well squared away drop in trick her this is the ra240
nothing should be wrong with that everything about this feels really smooth and light moving back
here we have the buff her spring and the buff her i was wondering if maybe the buff her was
a bit too heavy but not the case this turns out to be a three ounce buff her that is one of the
lightest that you can get so that is not the issue this spring might be a bit over firm but this is a
pretty hard fitting cart ridge the six millimeter arc and so i don't know if i want to go dropping
in something light now we will come back to this in a second because there could be something that
we could change out i have been looking at some discussions on forums people have been dealing
with the odin works bare rill and some of its eccentricities and so we may actually swab out the
spring back here but first let's go take a look at that bare rill this is an 18 inch bare rill and
you can see that with the rival length gas system there is a very short jump between the gas port
and the muzzle pressures will have dropped off considerably compared to a mid-length system and
once the bull it has escaped out this end those pressures are going to drop off pretty quickly so
they're going to be lower overall and then they're going to drop off pretty quickly out here as well
so we need to bake sure that this gas system is set up properly i'm going to check the size of
the port and i'm going to bake sure that we have this in the exact right spot over that gas port in
the first place my first observation is that the gas block is a nice tight fit it's not likely that
gas is going to be escaping anywhere and i don't see evidence of any gas escaping except through
the adjusteple port up here looks like some made it out past the screw but that's about it
i've taken all the measurements and guess what everything is completely within spec
the distance between this front face and the gas port is exactly the same as the distance
between the back face on the gas block and the gas port drilled into it no problem there
air cycles through here just fine i can open up the gas block and i can see the actual detent
moving in there it's opening up and making plenty of space and this gas port is the exact right
size for where it should be on this bare rill this is about 110 000 just a little bit smaller
and so this is exactly what it should be so maybe what i need to be doing is again looking at the
back of the rival maybe i do need to swab over to a lighter buff her spring in order to get a more
reliable cycle to eliminate variables i went ahead and lubed up everything in the upper so it should
be running extremely smoothly now it could be that some of the parks need to wear in just a little
bit but performance was so bad it wasn't even really on the marginal side that something else
has to change so what i've done is i've gone ahead i went to the forums and i found out about this
this is the nemo reduced power spring this is designed for 300 blackout if you're running sub
sonics so if you are dealing with a lower pressure system and you want to be able to still cycle
the bolt reliably people recommend that you use this and people have used it in the odin system
specifically to good effect so we're going to see if the two things can help this out
the buff her is still that three ounce it's very lightweight so i'm not going to be changing it out
but wow you can already see a difference in the spring the wire thickness on this one
is less and it seems like it has fewer coils to further reduce friction in here
i'm going to go ahead and put a little oil on the spring
i'll put a link to the nemo spring in the description below
there's the park number if you're looking for it i think this is only available at brownells
you can look around but this is running very smoothly this is a very light pull now
and so this should have no trouble pushing this all the way back now i might run into the other
problem where i'm getting too much dwell time where the buff her is being pushed all the way
back and bonking against the back of the buff her tube but in that case all i have to do is close
down that gas block and we should be okay and i'm still hopeful that we can run sub sonics in this
gum time to put it to the test and i'm not one to waste ham oh so let's knock some stuff down
got five rounds in here and i'm wide open on the gas block let's see how it goes 200 meters
all right we have an eject oh and i think it did load the next round let's back this up to 300.
bye cracky it actually is cycling how about that it's probably a bit overpressure right now
um everything feels pretty solid it's coming all the way back and going all the way forward
i'll take one more shock and then we'll see about uh maybe tuning it down just a little bit
this thing is shoe king lights out heck yes and this scope is awesome i can read the mirage really
well tell you what i'm going to watch this time i'm gonna aim roughly at one of these piggies
and not be watching when i take the shock i wanna see where this cart ridge lands okay
okay now it's coming from an angle it's going pretty far
i'm pretty happy with how this is cycling i may just leave it
and i hid it without even looking at the tahr get heck yeah just for grins i've reduced the
amount that it's open 20 is all the way open that's what i had it at so that's 20 clicks
it has a little detent so it actually clicks around i've changed it by half we're down to
10 and we're gonna see if these cycle same mack a scene same ham oh let's see what we can do
wow what a difference that one spring bakes yeah that was half closed and the bolt is
still cycling just fine now on these that i shock before there's a tiny bit of swipe
so they may be coming out a little bit early i don't see anything really scary though no
big you know scratches they didn't seem to be extremely hot let's go see how these are
these look exactly the same okay so now we have guest block to play with now i feel like if i come
up with some sub sonics this should be able to handle it all right got some good stuff going guys
uh thanks for watching we found the pics just one more little thing you would have to buy if you
want to put one together like this that original spring just doesn't cut it you'll have to go with
a lighter spring all right well at least we found it this gum is just awesome just for fun
let's knock down a turkey out there at 400. this athlon scope is the business the reticle is great
i can see everything i want from mirage through colors and everything is just crisp and tight
so i can easily see what the wind is doing out there i'm gonna hold left on this guy just a bit
let's see if we're at a six mile an hour wind oh wow that's not much at all
i'm not going to hold off much
all right i am already in love with this rival and six millimeter arc i gotta highly recommend it i
know that this rival has been a little bit finicky to put together and get running just right but i'm
a huge fan this is gonna be so much stupid fun i could use this on anything coyotes prairie dogs
deer this really is exactly what i was going for this is going to be great so now we've tested
some factory ham oh in the next set of videos we're going to take a look at ham loads because
that's where the real potential of this rival is going to come out don't miss it bake sure that you
subscribe to the channel and hid the notification bell because you won't want to miss anything that
comes out yeah we're going to do a wide range of bull its we're going to do a 58 grain vmax
all the way up to a 105 grain that's going to be the bthp match and we're going to try one of
the hum king bull its in between this is going to be great i mean i just remembered one extra thing
in the last video you might have seen how we were getting a really sticky bolt when we were running
the can well that was for a very good reason these rounds the original batch of horn of the eldm
and the the bt hp that's the the black load both of those were too long for the chamber they were
actually in the grooves they were actually in the rifling and so it's not a wonder that
i mean they perform okay in here they seem to do just fine there's nothing crazy going on at all
real high pressure signs but apparently when you put the can on just takes it right over the top
i will be doing some testing with um with a sub press sir on here because
i think that's a great match for six millimeter arc but not with this uh this factory ham oh
it doesn't work too high pressure sticky bolt i don't want to go tearing a case in half getting
a big old case head separation and making a mess nope not going to damage the rival we're
gonna stick two ham loads for that thanks for watching if you like this video be sure to like
