This offers extreme lubricity with a friction coefficient of. The carriers patent pending design features unique shrouded and forward facing gas ports that have also been re sized so that gas is vented differently to a standard carrier.
This results in a system that runs flatter with a smoother energy pulse. In addition the system also runs cooler and cleaner, there is also less pressurization of the upper receiver when running a suppressed barrel.
The flared boss at the tail of the carrier enhances the BCG's position within the buffer tube at the time of cycling and allows for a flatter more controlled reciprocation of the assembly.
The ultra smooth head reduces wear within the upper receiver. The BCG's weight helps to increase lock time with smoother operation.

Total voters Messages Reactions I would like to hear from people who have experience preferably with all three or two of the three I mention.
PTR 91 GI vs CAI C308 vs AR10
The thing I'm most concerned with is reliability, which ever rifle I get will be shot with iron sights exclusively, and steel cased 7. If I go the AR10 route I will need to know who makes good metal 20 round mags that fit PSA lower, never been a fan of Pmags and I know they won't hold up to rough use like metal mags will. The AR10 would be the cheapest but I want the best reliability I can get, this means without lube as well, this will be also a potential shtf weapon.

The top hole below the gas key had raised edges. Not sure how that passed through quality control. I sent it back and went with a higher quality company, coating and material.

Thread Tools Show Printable Version. C ground bolt carrier, now what? Hello everyone, I picked up a C from Cabelas awhile ago and brought it home for an inspection, here's what I found. The bolt is 1. I checked my bolt carrier and someone has ground off an eighth of an inch to create my cocking tube gap.
Finally, I checked bolt gap and its at. I've taken it to the range and ran 60 rounds of chinese copper washed NATO and it ran flawlessly. Rifle cocked and cycled fine, just shoots about 8 inches high at yards.
My question is how should I start off to fix bolt gap with a ground carrier. Are their any experts that can give me a solution. I hate to mess with this rifle since it actually works correctly.
Thank you. If the rifle works well and you can cock it without a hydraulic press then there isn't really a problem. I've not heard of people grinding the bolt carrier to set the distance from the cocking tube but if it ends up with the proper gap it shouldn't be a problem.
Your bolt gap of. Its about right where you want it after its been fired a bit. The only thing I can see is that if you want to swap out parts from other part sets you might need to do some fiddling.

Otherwise have fun shooting. Ok, I might just buy a decent locking piece and oversized rollers, because I've heard you lose some gap after it's broken in. I'd like to get my gap at.G3 bolt assembly German Airforce Way
The bolt gap tends to get a little smaller in the first few rounds fired because the barrel can settle against the retaining pin. Its not something you'll see change a lot after that other than for wear.
It will take a lot of ammo downrange to wear it If the rifle is functioning fine at. The idea that you should go to a. As your bolt gap increases the bolt speed increases because the "locking" delay is reduced so its not a good idea just to open it up. I know there is a tendency to want to fiddle and fool with it It doesn't always make sense when things are working however. Keep an eye on things and if your bolt gap does get smaller go to bigger rollers or try swapping out locking pieces.
You will probably have a lot of shooting in before you need to do that though. Thanks for the help, I just needed a solid second opinion. I would leave it alone to. I have one with a gap of around. Runs great and had around rounds threw it. I would work on getting it sighted in correctly.Remember Me?
The good, the bad, and the ugly. Last Jump to page: Results 1 to 10 of Thread: Century C Thread Tools Show Printable Version. Century C As you know I bought a used Century C rifle from another member this week.
Since they came out I've wanted to examine one to see how or "if" it was different from CAI's previous models. The Century marketing team spent some time and money trying to convince the shooting public that the C wouldn't suck like the previous Cetme's and spread the word that they had partnered with PTR Industries to build these rifles.
This rifle had approximately rounds through it over the course of 1. Issues that I recall were "hard recoil", "bolt not closing all the way", "bolt not picking up rounds from the mag", and finally "recoil spring sticking inside carrier tube". There may have been more issues that I missed. The welds, fit, and finish were way above par for Century. It's what I'd call "lipstick on a pig" after going through the rifle.
I don't know how much work PTR performed on the rifles, I assume that they pressed and pinned the barrel, welded the trunnion into the receiver, welded the cocking tube in and mounted the triple, and painted the components. It would make sense that those operations all be done in one place.
Then all CAI would need to do was drop in the components and add the lower and furniture. That's my guess. Upon receipt the "recoil spring sticking inside carrier tube" was the first issue I needed to address at the gun shop as it was locked up in the assembled rifle and they couldn't open the bolt to check for a loaded chamber.
I pulled the stock pins and the carrier came out with the butt stock. The carrier issue turned out to be kind of funny. First thing I did after using a rubber mallet to smack the carrier off the recoil assembly was look through the carrier tube. The pin that runs diagonally right to left to hold the bolt pawl in place wasn't down below the tube wall and there is a large burr at the top of the hole.
The Cetme recoil guide bushing was likely hanging up there. A tap with a hammer and a punch seated the pin and the burrs were removed with a Dremel. Last edited by holescreek; at PM. The next issue was "hard recoil".
