Reviews for T.i.N. coating bolt carrier? - M4/AR-15

[judoguy]

Fellow calgunners I am in need of some reviews and personal experience regarding T.i.N. coating for bolt carriers reference M4/AR-15 rifles.


Reason:
I recently got tasked with the team's armory. About 20-25 Colt
M4 rifles are individually assigned to each operator. We have a good mixture of older M4's and newer M4's which I have tested and used both.

I have used both the new and older M4's for training within an indoor range and also an outdoor range. During the outdoor range shoot, I went through about 200-300 rounds with my rifle. Although I started off with a fully clean and lubed rifle , the rifle was in desperate need of oil only after a half day of training. There really was no problem during semi-auto but once I got into the full-auto and 3 round bursts I started to notice the rifle was slowing down in rate of fire substantially. Of course being outside in the constant dust for about a half day did play a factor.

I had to use oil a few times during the training just to keep my rifle from jamming up once it got pretty bad. Once again the problem was showing up more and more with the rifles during full-auto and 3 round burst drills.


Possible solution:
I thought maybe T.i.N. coating the bolt carrier whether in part or full would give the rifle some more time before the full-auto slows down the rate of fire due to the need of heavy oil after several hundred rounds or maybe even fix the problem.

My current off duty Glock has the barrel T.i.N. coated and I have had nothing but good experiences but this is a very different application.

I cannot get new rifles for the armory nor new or aftermarket bolt carriers either so this was an idea I wanted to present to my team.



If there is any calgunner with T.i.N. coated bolt carriers that have gone through a high number of rounds, please let me know your experience whether its even worth the money. I have to ask my supervisor for the funding.

Thanks

What about the NIB BCG's? I thought TiN coatings were for hardness and scratch resistance while the NIB coatings require less lube if any at all.

Try the LMT Enhanced bolt / carrier and group. Gene at LMT can help you out with all the tech specs and it was designed to upreliability on FA guns. They were designed for the PIP for M4 that was canceled. Armswest (Jim Sullivan) also makes a mod to up the reliability of the guns in FA, he was one of the original designers of the M16. If you are looking for just the bolts JP makes a CrN bolt , LMT's bolt is special coating, Robar sells NP3 coated bolts. Are the guns slowing down because of carbon build up on the back of the bolt?

Check out kandmblasting on instagram. They do more than just tin.

[judoguy]

The feedback I've been getting and also have been reading is somewhere in the ball park of

Nib / micro slick/ tin

Although I am being told tin should out last all other by durability. Any thoughts ?

[shafferds]

Tin or altin will out perform. I know guys that have 7000 plus rounds on tin coated bcg's and they keep on ticking.

[bigbearbear]

What about NP3 Plus?

Parkerizing (phosphating) holds oil better than any of the other finishes you are talking about.
If your oil is going away too soon, look at a better oil or even a really light grease.
No fancy finish is going to fix a lubrication problem.

[whiskyjacked]

2nd on the grease option. CLP's and oils will burn off during long stretches of full/burst shooting. Leaving more of a gummy residue of fouling and burnt oil. Look at a very light coating of firearm grease. There is a mil-spec type, but I imagine any on the market are good enough. I still use it in some of my gear. A little goes a long way. I'm still on the same tube I've had for 4 years.

I will coat my gas rings with Slip 2000 EWL grease, it stays. I also use TiN cams in my BCG's. I got tired of replacing them as they get cuts into the sides.

So far they are holding up well, most of the coating stays, what comes off is slight without the cutting from parked cams. So far I'm liking melonited bolts and TiN cams for wear.

Don't believe the hype. Change your oil

[ElvenSoul]

Dindu nuffin for me

[fritztkatt]

So you were shooting burst and full auto on the same rifle?

I'd switch lubes.

[Paul053]

I recently bought a bottle of Lucas gun oil and it seem to stay in place better than my slip2000. All the work Der oils seem to have the same viscosity but Lucas seems to thicker with the consistency of snot/splooge. It doesn't move when the rifle is stood on end in my safe.
