CMR30 Quick Start Guide: Video

Field Stripping, Cleaning, and Reassembly has never been easier.

Gun Features 

Hey everyone, thank you for joining me for this version of KelTec’s Quick Start Guide. This is the CMR30.And we'll go ahead and take it out of the box.

Okay, the first thing you're going to see is your CMR30 and a couple of 30-round magazines. However, what I'd like you to do is pull out your manual first and get to know this really well. If you have any questions, our information is on the back. It has our web address and our phone number. Not seen in the box is your warranty, and you can find the information on your warranty on page 19 of your manual. Let's see what else we have in here. A set of Magpul MBUS, these are excellent sights. If you choose not to use an optic, you can use these flip-up sights. It comes with both a rear sight with two apertures and a front sight that's fully adjustable. These are adjustable for both windage and elevation. We've got a sight tool kit here for your front sight, two 30-round magazines, and then we have the rifle itself. Hang on to your box for long-term storage.

One thing I'd like to point out is the orientation of these Magpul flip-up sights. If you're not familiar with these, you'll just want to take a flathead screwdriver, go ahead and loosen it up, and pop the screw out. Then you'll slide the front sight on so it's oriented like this, and then you can just go ahead and put that screw back through and tighten it down. And then the rear sight, same thing, just loosen it up with a flathead screwdriver. The orientation is like this, so that is the back of the sight that you will look through, and that is the front of the sight. You slide that on like so, line up the slots in the Picatinny section, go ahead and put your screw back through and then tighten that down.

Some of you may have noticed that the nut popped out of the sight as I pushed the bolt through. It flew over to the side of the table. So when you go to put your sights on and you're pushing these back through, make sure that the gun is faced in this direction so that those nuts, if they pop out, will hit your workspace and not go flying across the room. But that is how your Magpul MBUS sights should look on your CMR30. They fold down, and to deploy them, there's a tab on either side of the sight that you simply push down, and they pop up.

Alright, now that we have our sights on, let's cover the features of the CMR30. We'll start at the muzzle end. It has a 16-inch barrel, and it is threaded 1/2-28. It does come with this thread protector on here, like we covered. It comes with the Magpul MBUS sights, which is an awesome feature. It has a full aluminum Picatinny rail on the top and also an aluminum Picatinny rail system on the bottom.

The charging handles are on both sides, so this is an ambi carbine, and they are non-reciprocating. This will be your bolt stop and release. This lever here is the lever you push down to bring your stock back in. To pull it out, you simply just pull it and then push the lever down to push it back in. You've got an ambi safety on both sides. If you're familiar with the PMR30, it's exactly like the PMR30.

The magazine catch is a European-style heel catch, which is on the back of the grip right here. Simply push it and pull down with your index finger. One thing very important to note, guys, is the serial number on the bottom aft of the gun here. Make note of that and put it in your safe. You never know when you might need it.

Alright, I just want to talk about ammunition for a minute. You always want to use high-quality American-made ammunition. For instance, we have this CCI Maxi-Mag stuff. This is great ammunition. You also don't want to use anything smaller than a 40-grain projectile. Start out with some live ammo. Let's load this thing up.

As I mentioned earlier, you want to pay close attention to this rim window. Again, it's about three quarters of the way back on the feed lips in the magazine. That is where the rim of your cartridge is going to start in the loading process. So, you are not starting from this notch here, and you're not starting from the front. You're starting from the rim window, which is right about here.

The best way I've found to load this by hand is to place the magazine in my strong hand and use my strong hand index finger to push down on the cartridges as they go in, and then I push back my support hand to make sure that the cartridge is seated all the way to the rear of the magazine. It's very, very important because you want these rounds to stack properly so that they feed properly out of the magazine. That's two, three, and again, you'll see that I'm pushing down with my index finger and pushing to the rear with my thumb, and this is going to give you some feeding success.

And this is not your typical gun, so these are not your typical magazines. So, I highly recommend you use this technique if you don't have a speed loader for it and you're loading by hand. And this also eliminates denting on the brass. If you dent the brass, that can also cause feed issues because it changes the shape of the cartridge. And as it comes out of the magazine and goes into the chamber, if that cartridge has changed shape and it's not straight, then you're going to have some feeding issues. So, that's it, that's all 30 rounds. I made it look easy because it is easy. You can do this. Just make sure that you're using that window, and make sure that you're only putting 30 rounds in your magazine. It's that easy.

As a rimfire gun owner, you should be aware of rim lock. I will explain what rim lock is right now demonstrated on this magazine. Rim lock is when the round on the top is behind the round on the bottom. So what I mean by that is if this is the top round, and this is the bottom round, this one should be all the way to the rear of the magazine, while the top one should be resting on the rim below it, just like this.

What rim lock is is when the bottom round rim is in front of the one that's on top. So what happens is, as the bolt comes forward, if it's coming this way and trying to push the round this way, it's grabbing both rounds, which is locking them both into the magazine because this one is not yet on top and ready to feed into the chamber. Whoa!

Alright, guys, I'm going to show you the manual of arms now. To push the magazine in, you simply put it in like you would a handgun. It locks in. Again, there's a heel-style catch there. Pull the stock out, simply just pull it out until it stops. If you want to adjust it, you've got different positions here. And to charge the gun, you simply just pull back on the charging handle, either side. Again, it's non-reciprocating, so as you're firing, it does not move. So if you want to grip the gun with your hand over that, that's not a problem at all. Retract the stock, push the button down, pull the mag out. To drop the bolt, you can either pull down on the bolt release here, or you can simply just pull back and let it go.

Field Stripping 

Let's disassemble the CMR30 for cleaning. You're going to need a gunsmithing or similar hammer and a punch or something similar to this KelTec screwdriver. There's an assembly pin just above the trigger, so we're gonna have to take that out first. So we'll rotate the gun over to the right side and go ahead and gently tap on that assembly pin until it breaks free. Bring the gun back over, and then just pull it out with your fingers and set that aside.

The next thing you want to do is pull the stock back and slide the grip off. That's your whole grip assembly there. And the next thing you want to do is bring the bolt back out through the stock. So just grab the charging handles, push them back, and then you can finish the job with your fingers by pulling the bolt carrier back.

What you'll want to do is make sure you have the stock pulled out with enough clearance to get the bolt and carrier assembly out, and then what you want to do is pull up on it so that your carrier assembly is vertical. Rotate it 90 degrees to get the buffer out of the stock assembly. If you want to take your stock off, there's really no reason to, but you would just simply slide it all the way off until it comes off the receiver of the gun. That is your field strip of your CMR30.

To put the stock back on, you just have to line up the notches in the receiver with the notches on the front side of the stock. It can be a little tricky, especially doing it for the first time. Just line them up and get them in there firmly.


Alright, for cleaning and re-lubing your CMR30, we highly recommend Lucas Oil products. This contact cleaner is excellent for getting all of the carbon and debris out of your CMR30. As you know, rimmed cartridges tend to get pretty dirty, so we recommend this stuff for getting all that stuff out of there, and then when you go to reassemble your CMR30, we recommend this CLP to keep it running smoothly.


Now that we're cleaned and re-lubed, let's reassemble our CMR30.

Step One: You're just going to go in reverse order, so start with your bolt carrier. The orientation is going to be like this as it goes forward into the receiver. So, you'll want to again rotate it 90 degrees, turn it in, into where the buffer tabs are lined up in the slots on the stock itself. You may have to slide it back a little bit just to get the carrier down into where it needs to go.

Step Two: Then you can bring the whole assembly up, line up the slots on the bolt with the slots on the receiver, and push the bolt all the way forward. Remember, when you have the stock extended like this, leave yourself enough room to go ahead and slide the grip assembly back on, and you want to get it as far forward as you can.

There's going to be some spring here, so what that is, your recoil spring assembly pushing the grip back. You'll have to hold it on, grab your assembly pin, and go ahead and push it through. Give it a little bit of help with your gunsmithing hammer. Make sure it's flush. And that is your CMR30 reassembled.
