I like the .308/7.62 round. I already own an Indian Enfield, a Savage 110 Tactical, and a Ruger AR762 in 308. This purchase was a Grab-A-Quote and they got close to what I was willing to pay.

Grab a gun is on it again. Can’t beat the price. Rifle is as good as it gets and goes bang like it’s supposed to.

AWesome gun at an awesom price
Bought this because I wanted a 308. Price was where I wanted to pay. Shipped quick with no hassles. Took it to the range and it shot better than expected. Had 5 shots within 1" at 50 yards. Moved to 100, spread out some. Added a scope for second trip out. Shot same at 50 and much better at 100. Used steel cased, cheap ammo. No issues at all!

Made a good impression on me
Seems well made. Haven’t shot it yet. I Compared it to one made on a Heese receiver and this one is much nicer.

Precise, Reliable, Cheap
Came with a 5 rd and 2 20rd magazines.
Magazines are the steel Cetme variety. They look and feel very well made.


The worst thing about the rifle I received, was that I ran out of windage adjustability and it was still grouping about 1 inch to the right at 50 yards.

Pulling the charging handle was very difficult. Took apart the charging handle, then clean and lubed the cocking tube, now it's smooth like it should be.

Came with two pretty big scratches, one on the left side of the receiver, one on the right side of the rear sight.

Magazines feel like they fit kind of loose. Didn't cause any functioning problems.

Doesn't come with a front sight tool. You can find em online, but I fabricated my own.

Other Thoughts:

The trigger is okay.

I didn't expect the rifle to be perfect, because it's really inexpensive, but I'm disappointed in the sight alignment.

I guess my options are to...
1. Contact Century Arms, and whine to them about it
2. Grind the welds off the rear sight, move it a little bit to the left, then weld it back on. (I know my limitations, and would probably mess this up)
3. Get a scope, and a cheek riser.
4. Hold 2 MOA to the left everytime I shoot it

Love it
Couldn't be happier, love this rifle and at the price I paid makes it even better. Fired 200 rounds of steel cased ammo, no problems. These rifles are getting harder to get, because the surplus parts are becoming scarce. Buy one before they're all gone

Great 7.62 Main Battle Rifle at a Great Price!!!
I have wanted an HK91/G3- type rifle for years but was put off by the price. I saw this one for less than 1/2 K and jumped on it like a duck on a June Bug. I took it home and disassembled it, removed the packing grease, and cleaned it thoroughly. The fit and finish is very good and everything appears as it should. With the Holidays I have not yet had the opportunity to fire it yet, so I can not yet evaluate function and accuracy. This rifle has a four-leaf rotating rear sight that is graduated for different distances. Century has also welded a Picatinny Rail on top of the receiver for scope mounting. Unless this rifle won't shoot a reasonable grouping, I am very pleased with what I got for the price. ERSJR

Century Arms C308 Black 

Century Arms' powerful C308 Synthetic Rifle is a popular take on the G3. The 18” chrome-moly 4140 barrel features 5/8x24 right-hand threading, for the most popular .30 cal muzzle accessories. Built around a reliable roller-lock delayed blowback system. Proprietary Chevron compensator directs gasses upward to help reduce recoil, resulting in greater control of the rifle. Mil-spec 1913 Picatinny rail is welded to the top of the receiver for easy accessory mounting. Fluted chamber for reliable cycling and extraction. 


For the price (got it at a steep discount) it's a good rifle. Reliable, fairly accurate (2 moa or less), magazines are cheap. The muzzle brake is pretty good, which surprised me. It comes with two 20 round mags and one 5 round mag. The iron sights are decent. I recommend putting a red dot on it. For under $700, its a H&K 91.
