Gotta Have Some Forplay

by

I recently switched from a colt bolt carrier to this one in my new build. I wanted to give it a good amount of time before I reviewed it. At first I didn't like it in the slightest. After all I've read in my mind I figured you slapped the thing in and just wiped it off when you were done. It's just like every other bolt out there. You still have to oil it still have to scrape it and you still have to use cleaners. But I will say it is easier to clean overall. The first 200-300 rounds were rough. Shooting auto(Slide fire) was damn near impossible. Would jam right on up. Switched to the colt bolt and not a single issue. Back to the WMD and every third was a misfire. But lone behold it just started working great one day. Not a single issue since. Only giving it 4 stars because in reality it's as if you have to pay 150 bucks for it to work like it should. Could just be a noob and just don't know what I'm talking about but i expect things to work from the get go. But I do like the bolt once it's been worked in.

a winner

Just perfect like last one. So here in bought again.

Beautiful. Bring on the excess carbon and zombies!

Smoother than (the liar) president Obama in 2008.

The best I have ever used.

by

Purchased June 2014.300-400 rounds fired every session. No failures,just a little darkening of the finish due to mag dumps,half of my ammo is spent this way.Very pleased, see no reason to try the new Relia-Bolt everyone is talking about, I'm sure if the had tried this BCG they would never mention the above. Now I have said this let me knock on wood

First nickel boron BCG

by

These were smooth to the touch. Easy to clean and moves fairly easy without any lube. Much smoother than the regular black phosphate finish

Sweet looking BCG

by

The WMD BCG with polished finish looks amazing! It operates very smoothly and provides great contrast to the black anodized upper receiver. Turned out that I didn't need the hammer because I went with a drop in trigger pack. Highly recommend this item for any builder!

Great product

by

Very fast transaction and shipping thanks! Everything looks and works great.

Great product

This is a great product. As soon as received it i went to the range put 200 rounds though it with no Ftf or fte. Ran. Very smooth and it was easy to clean. I would recommend it.

Great service as usual

Wow

by

This is by far the smoothest BCG I have owned so far. Hands down better than your normal mil spec phosphate bcg. A tad pricey sure, but in my mind it was money well spent for my second build.

UPS lost my initial order and Brett promptly shipped out a new one via Fedex. You can't get better customer service!

Works great.

by

Use it in a FA gun and it will run more reliably for longer before I have to clean it. The NiBor finish looks nice too.

Excellence

by

The product I ordered has been excellent, but I am extremely pleased with primary arms, the shipping speed and attentiveness to the customer is superior. Thank you.

Great BCG!

by

The BCG has a very smooth Nickle Boron plated surface.Despite it having high lubricity due to the NiB exterior, a little oiling still assisted with the initial wear-in with my barrel.Bolt Carrier Group cleanup is a snap.

Worth every dollar!

by

Dropped right into my DD no problem. Cycled 3 full mags with no complaint. Very easy to clean like I expected.I highly recommend it.

Fantastic

by

Ordered WMD nib-x bolt carrier. Product was in stock. Price was spot on. Communication was great. Shipping was fast. Item as described and packaged well. Will shop PA again.

SLEEK!!!

by

The quality and attention to detail of this WMD NIB-X Nickle Boron Bolt Carrier Group is of phenomenal quality.Tight fit and smooth operation, I couldn’t be happier. The ease of cleaning and the durability of the coating make it well worthy upgrade to my M4.This is exactly what I was looking for in a quality BCG and hammer. I like it so much that I WILL be purchasing additional WMD products for my M4.

Very smooth operation

by

This WMD NIBx bolt carrier is worth the upgrade. Along with the hammer it almost seemed like the carrier was on bearings. I did wipe it down with LP lube before use but it ran flawlessly in my DPMS. With the added hammer I noticed a little smoother trigger pull. Service and shipping were great!

Hard to say since I haven't gotten to use it yet

by

the build quality seems great, except the cam pin was way too tight. I sent it back to WMD and they're sending out a replacement. Great customer service, they actually answered the phone both times and talked the problem out with me. I'm sure the replacement will come back perfect as I hear pretty much nothing but good things about this company. If so, I'll raise my rating to 5 stars.

WMD makes one fine bolt carrier

by

Put this BCG into my Spikes Tactical upper and has run flawlessly for 1,000 rounds so far with minimal lube. The NiB coating is not as shiny or "clean looking" as chrome. It has a darker tint to it and "looks a little messy" even when perfectly clean. I already knew this before buying it so could care less about appearance, as long as it functions well. Primary Arms has the best price for a NiB BCG WITH NiB Hammer.
