I have narrowed my (soon) purchase down to these two rifles.

I'm looking for anyone who has hands-on experience with either rifle.

Thanks in advance for your input....

I have a LAR-8 Standard Operator. Here are my thoughts:

Pros:
-it is a VERY smooth-running gun. The action is smooth, pleasant, and the rifle is so-far 100% reliable. I run mine a little wet though, so that the extra G96 oil I put on it probably helps.
-the recoil is milder than you’d expect. There is definitely more recoil than my AR15, but it’s more of a push than a smack.
-compared to my AR15, it doesn’t get very dirty. It is a clean-running gun.
-it seems very accurate. The scope I’m getting is a long-lead-time item, so I’ve had the rifle for a couple months and have just been using iron sights. However, even with the iron sights it seems surprisingly accurate. We’ll know more when I get the scope.
-I’ve used 150gr and 168gr in it; it liked the 150gr but LOVED the 168gr
-The over-all build quality is very high. It is very well machined and fits together very tightly.
-If you have the option of the vortex flash hider get it; it almost completely eliminates the flash.
-it looks good. Seriously, it’s a sexy gun.

Cons:
-I’ve handled ARs with both Teflon-finishes and hard anodized finishes. The LAR-8 has some kind of hard-anodizing. While it looks good, it can be hard to clean. If you use a white rag to clean it it leaves lots of lint on the gun when compared to the smoothness of teflon. This can be cleaned-up though with a quick pass of an old toothbrush.
-I’d like to be able to remove the free-float tube for cleaning but that looks difficult given the size of the gas block with built-in pop-up front sight. However, I don’t think this is a major issue.
-The issue of the FAL magazines bothers me. RRA has polymer 20-round FAL mags for it… while these mags feel a little flimsy they are actually excellent products and function perfectly. They are made of Zytel; a DuPont polymer that is also used to make S&W M&P pistols. The Israeli surplus FAL mags also run perfectly. The DS Arms mags don’t work at all in the LAR-8…. Save yourself the wasted money and ammo and don’t even bother trying the DS Arms mags. If there were new production 20-round FAL mags that worked in the LAR-8 then that would solve all my problems. Please be aware though, this is just my own OCD nature showing-through on the mags issue.

Over-all the LAR-8 is a great gun. I am happy with my purchase.

Get an Armalite instead. The REAL AR10.

I've had an LAR8 Predator for about two years now... I compete with it in 3-gun and occasionally a long-range steel match. I've not had a single thing go wrong... I did replace the trigger with a Timney and have had nothing but success with that. I have a US Optics 1.8-10 scope on it, which is a bit heavy, but nothing that I can complain about.

Its consistently under a one MOA rifle with my handloads.... 178 Hornaday AMax at 2500 fps w/Varget...same velocity as the LR-118 Mil load.

Overall, for the price I believe its a better value than any other 308 battle rifle out there.

I have had a rock river lar8 20 inch a4 for about 2.5 years and it has been a damn good rifle accurate and reliable . I dont shoot precision matches or try extreme long range for number one I dont have any place to stretch it out and number two I feel it is better to practice at a more likely range which is 50-300 yds max. the rifle is a coyote killing machine and I love the polymer mags . at 300 yds I can shoot 4" to 6" groups off my back pack or using shooting sticks and that is good enough for deer and coyotes

I recently bought a LAR-8 and am very pleased with it. The polymer has from RRA work great and there much lighter. I haven't used it a lot but so far I've loved it, I have a stock RRA two stage trigger in it and its awesome.

Another vote for the LAR-8.

My 20" A4 LAR-8 has been slightly modified since purchased - Daniel Defense Lite Rail, replaced the fixed stock with a Magpul CTR, and MIAD grip. On top is a Vortex PST 4-16x50 FFP mounted on aluminum Leupold Mark 4 rings.

Approximately 800 rounds down the barrel, not a single issue. 100 yard MOA all day with 168 grn American Eagle M1A ammo. The rifle does not like WWB 147 grn Nato ammo for some reason - groups open up to minute of barn door.

Ignore the controversy regarding that RRA does use standard SR25 pattern mags. I use both metal FAL and RRA's new polymer mags without issue. Admittedly, all my mags were purchased through RRA. Yes, you will read that a few guys had trouble using some surplus FAL mags - it is always a crap shoot to save a few bucks.

Search though this site, there are many RRA LAR-8 owners posting examples of long range accuracy and reliability from their rifles. The LAR-8 is a solid 308/7.62 platform and matches up nicely against 99.9% of the other AR10's in the market.

I purchased an LAR8 Comp Elite about 3 months ago and have been putting it through my setup process.
On first use I had lots of misfeeds and fail to eject. The extractor was actually pulling the brass rim off the off the casing in a big chunk leaving the casing in the barrel. Had to push the brass case out of the barrel with cleaning rod. Took it home, tore it down, did not find any defects upon inspection. Removed the ejector, oiled it good. oiled the entire system in the appropriate places. Poly mag seemed OK. As it turn out the mag did not feed because brass was not ejected from barrel. So failures seem not mag related.
Back to the range with the poly mag and a wet gun and it ran perfect. (I think RR says gun is ready to shoot out of the box....but not true for me) I suggest and have had others say the gun needs to be run wet (well oiled). After about 500 rounds without failure now. Gun seems to have become more smooth. RR says no breakin required, but I would say my gun is only now beginning to operate much more smooth after a little breakin. It shoots the specified MOA of 1-1.5 @100yrds.(I use178gr factory round) No problem with the poly mag. I have several FAL mags and it accepts and feeds them without problem. I purchased 30 round FAL mag and it works without problem. Recoil not as bad as I expected, but notably more that a 556. Much better after 500 rounds.

I wanted COB weapon with more knockdown than 556 rounds. I have attached a 4X scope which is sufficient for100yrd shots. Longer shots I move to my sniper weapon. I suggest a scope with 3-5 inch eye relief. It is not comfortable for me to be crouched up on a scope when shooting 308. I also do not like to be cramped up on the gun, so I extend the butt stock to full length position to give me a more firm and stable grip on the gun. (Its a heavy gun and ergonomics are important) Put tall scope rings on the rail so scope lines straight-up with my eye and gun mounted firm in my shoulder. Have not found a rear pop up sight that fits with my scope position, So I added a Halo red dot scope mounted to a 22 degree off-set mount fixed to the top rail. The combination allows me to switch from 4X scope to Halo with slight pivot of the gun. Its a great way to move from 100yrd shots to 25-35 yard shots quickly.

Bottomline....this now my favorite gun.

Ditto! Best bang for the buck. Excellent quality and workmanship.
