I had a failure to feed today on my XCR. I have about 1 k rounds thru her and this is my first failure. I found the firing pin sticking was out and jammed in this position. I took the bolt out and pressed on the firing pin sticking out . It retracted back in. Then the gun works fine. Problem is , when I point the the bolt down, the firing pin protrudes out the hole. I didn't think this was normal. At home, I knock out the retaining pin and out comes two pieces of a firing pin. the small piece is about 9 mm. long. I'll call Robarms tomorrow.

Ok , so here is the question. I do alot of dry firing with this gun for practice purposes. Would dry firing cause the pin to break like this?


The dang things still works with a broken firing pin----unless the broken pin gets jammed. So what do you think.
 
Heck , I have snap caps for everything but 5.56. Duh!!!!!!!!!!!

Leek has crawled into his "shame hole" and is waiting for his red face to return to normal color.

Yeah because the ones you own are Old. Kinda better made, Old stuff really never have problems.

Everything usually in the first or second batches usually have some problems.

Robarms firearms kinda reminds me of a FN C9 LMG.

Chewing up rails,
not working on the proper settings,
Breaking firing pins,
launching barrels off,
Crude welds,
Sloppy machining.

Problems with Robarms Firearms, First 3 problems are what I heard about the XCR. Last 3 were old M96's .

Whoa dude, to much coffee this morning. What makes you think dry firing caused this? The guy with one post who says "yes it will, get some snap caps"? This was most likely just a bad firing pin, happens to AR's too. I think its more impressive that the gun kept working with a broken pin.

Let us know what RobArm says leek.

Except Garands, FN-49s FN-FALs, M-14s, 1903 Springfields ect.

There was a reason that FN-49s L1A1s (& C1A1s) got 2 piece firing pins during later production.

No centre-fire should be EXTENSIVELY dry fired. And rim fires should NEVER be dry fired (yes, there are competition guns which ARE designed to be dry fired)

Guns with broken firing pins should NEVER EVER be fired. This is because they are vulnerable to out of battery firing which can lead to catastrophic failure of the gun or uncontrolled cycling.
 
I called BS on this. More C7s and M16s are being dry fired in the government then an average joe did in his life time!! Iwould venture to say that most government rifles (at least in the non-deployed army) got dry fired more than fired with live rounds. Everytime the weapon is cleared, it got dry fired. A rifle that breaks by dry firing is not going to cut it.
 
Continuing to fire my XCR with a malf was stupid. At first I thought the return spring was stuck--------I did not know the pin was broken until I got home and used a drift punch to release the pin. The pin then came out in two pieces. At the range I did not even think of a broken pin as a possibility. I now see that this is possible and even have the gun function with it broke. Called Rob arms today. They want to see it and examine it. As requested, I will send the assembled bolt to them for inspection and replacement/repair. Alex himself called me back. He assured me a quick turn a round. HE told me I should be able to dry fire as much as I want. I believe a gun is not turly safe until cleared of ammo and hammer dropped-----pull the trigger in a safe direction. Of course ALL guns are ALWAYS loaded----------period -------tham them as such-ALWAYS.

My XCR had the mods------ie. the new firing pin with a polymer buffer installed. The repair will be done under warranty. I have also ordered three replacement pins -----------only $12.00 USD. I'll do a follow up. BTW, I live South of the border and my serial number is below 700.
 
just a question leek. You said you used a drift to remove the firing pin. Do you think it is possible that you might have broken the firing pin with the drift and that it was only stuck?

Not saying an xcr firing pin can't break or that I don't believe you, but I can't figure out how it would still fire with a busted firing pin
 
Leek: I don't suppose you got a photo of the pin? I am assuming the tip broke off, is that correct? Were there any other obvious signs of damage, etc, to the pin?
 
The firing pin broke near the tip---approx 8-10 mm from the tip. The drift pin is located near the other end where the trigger hits the "fat" part of the pin near the polymer buffer built into the pin. The polymer buffer actually slams into the drift pin stop. Removing the drift roll pin could not have broken the pin at the opposite end. I believe the pin got jammed in the out position ----about 1 cm. of it was exposed. As the exposed pin ran into a round it was trying to load , I believe it got bent and therefore it would not retract until forced by my me. Hope this makes sense. Sorry , no pixs. The part has been shipped back.
 
Robarms recieved my bolt today and called me to tell me so.They are sending out a replacement bolt today to arrive by Friday. Less than a four day turnaround. They need my bolt to do testing and tolerence check out. This will take time and asked me if I would accept a new replacement bolt for a quicker turn around. Terra in service apologized for the inconveinence and told me she and the company appreciates my business and support. I told her I would spread the word of their support and timelieness.

When I talked to Alex he told me of some improvements to the XCR. The XCR's gas block has been improved. The new block will be hand adjustable/ field adjustable with no tool/ wrench. There will be five positions instead of the current four. The added hole will allow better operation of Wolf ammo , especially while the firearm is being broken in the first 300 rounds. The new gas block is downward compatable with the current design and current owners can upgrade their rifles to it. The 6.8 conversions will ship in August.

I told Alex that a small field emergency repair kit with all those propietary fasteners, firing pins, etc would be great to current owners if properly priced. He agreed and said he would look into it.

I like this company and have spent my $ with them . I also own a Robarms VEPR K----------a Ruskie RPK that Robarms modified to make legal here in the states. They are not perfect but they are a mom and pop operation that in my opinion deserve our support for their efforts. Its not for eveyone, but it works for me and I shoot it well.
 
I just noticed I spelled Broken ---"Boken" in the title. Typo , sorry about that. Some of us Yanks do know how to spell.
 
New replacement bolt arrived this morning----------4 day turnaround. Also got two backup replacement pins for my spare parts kits. I 'm disappointed I had the failure but am very, very pleased with their service and their commitment to my issue with their product. My XCR is back on line. I plan on extensively testing it out. I have shot one competive event so far with the XCR. I scored in the middle range. I blew it on the 100 meter head shot targets only hit one out of six. My problem is I don't have the eotech zeroed or have even tried a 100 meter shot. Everythig else was with in 25 meters --------no problem. The event I shoot is like IDPA but with EBR's and side arms. Alot of running, dropping and shooting. Last event , I had to drag a 170# dummy and shoot from cover while gasping for air!!!!!--------Dang , that was fun!!
