Retired JM

I own an Armalite AR10A4 carbine. It came stock with a 16 inch chrome lined barrel and a mid-length gas system. Are you sure the barrel on the one you're looking at was measured correctly? And welcome to the site.

Funny you mention Weaver's tactical line. I'm looking at a Weaver for the REPR. The Weaver/Midway USA scope really impressed me with it's quality.

Good luck finding a PST. All the local vendors around here (Here being SW OK/NE TX) are out and most online vendors like SWFA and Midway have them back ordered. The PST has become so popular that Vortex can't make enough of them.

LWRC doesn't really give any sort of guidance as to barrel break-in. They do recommend running 175 gr ammo like M118LR. So far, I've used only FGMM 168 and it's shot fine. I just got some Nosler OTMs so I'm gonna be experimenting with that. I'll be sure to post the results of my loads.

Personally, I don't care for it. Me and my boys got some free samples when I was in The Box back in '05. It really didn't perform very well for us, certainly not well enough for us to go away from SLiP. But if it works for you, then drive on with it.

While there's a sub-forum for LWRCi rifles, It's buried so deep no one would probably have noticed it. I've had an LWRCi 5.56 for several years now. It's a brutally reliable stick and is my "go to" rifle for any social encounter that may arise. I have always been impressed with LWRC's attention to detail and when they introduced the REPR, I wanted one. Unfortunately, all that attention to detail comes with a high dollar amount attached and I had to shelve plans on getting one until recently. A gun shop in OKC had one gathering dust and I cut a deal with them to buy it for 3K, which is pretty much at cost so I felt like I got a good deal on it. And here it is 20" barrel (heavy contour), 1-10 RH Twist. The barrel has been nitride treated inside and out. LWRC claims their barrels are good for 20,000 rounds. The bore and chamber on my 5.56 still look new, so I have no reason to doubt this claim. Giessle trigger, Magpul PRS stock and MIAD grip, Troy front and rear sights Here's a look at the piston system: The REPR comes with an adjustable gas system with settings for normal, adverse conditions, supressed and total cut-off. Probably the most unique feature on the REPR is the charging handle, located on the left side of the receiver. It's non-recprocating and the user can push inward on the knob and use it as a forward assist. The rifle is also a bit more ambidextrous than the usual AR in that it has an ambi mag release. Bolt Carrier Here you can see some of the lightening cuts on the BCG. These continue all along the BC and help mitigate carrier tilt as well as providing channels for debris to work it's way through. Both the bolt and the BC are Ni-Corr treated, which is very similar to a Robar finish. I took the Weaver/ADM off of my AR10 and am going to use it on the REPR until I decide on a new optic for it. Shooting Impressions: This is a heavy rifle at about 11 pounds unloaded w/o optic. Loaded up, it's scaring 15 pounds or so. It's a little heavier than an M110/SR25, but about the same for an M14 EBR. The added weight does give it one advantage - it really soaks up the recoil. Shooting this rifle is a true joy. The trigger is light and crisp, breaking cleanly at 3 pounds and the recoil impulse is a smooth shove rather than an abrupt push. Accuracy is scary good. If your fundamentals are sound, where ever you put the crosshairs is where that round is going (Using good ammo, of course.) Right now, I've got 120 rounds through it with no malfs to this point. I'm impressed with this rifle to the point of stupefication. I went out to our local 1000 yd range and after zeroing, hitting a steel silhouette at 800 was as simple as point and click. I didn't go out to 1000 because we had some humidity and haze that didn't let me get a good solution (FGMM ain't cheap and I'm not gonna waste ammo.) If ya gots the coin, gets you a REPR.

I'm a big fan of both Royal Purple Gun Oil and SLiP 2000 EWL.

Welcome to da site dere, doncha know. Seriously, welcome. Building an AR, regardless of caliber, isn't hard. Building a GOOD AR is a different ball game.

No doubt they felt overwhelmed by all the stupid things idiots do to themselves and others.

17. If the third cousin (twice removed) of a friend of a friend of a friend tells a story about how he had trouble with Brand X, it shall be taken as gospel that Brand X sucks and all other users of Brand X suck by association.

Present company excepted, right? <laughs>

Dude, out here on the plains, your wind call is crucial. Prior to PCSing out here, I thought I was pretty good at reading the wind. Texhoma showed me I had a lot left to learn. But it's made me a much better shooter.

Rifle: LWRCi REPR w/20 inch barrel Cal: 7.62mmx51mm Optic: Weaver/Midway 3-10x44, Mil-Dot Reticle Ammo: FGMM 168gr SMK WX: 50 degrees, Sunny, Full Value wind - 15 MPH gusting to 25 MPH, 27% Rel Humidity, 29.85 Bar. Pres. Elevation: 1200 FT ASL Range: 200 yds Notes: Wind played hell with my group. Initally dialed in 1/2 mil of left adjustment. Shots left of center reflect dying wind. The 2 shots at 6 o'clock are from the barrel heating up - they were shots 6 and 7 in the string; Elevated 1.0 mil to compensate.

Sorry to hear about your situation with trying to get a Noveske barrel. FWIW, My POF has a Rock 5R. Damn good piece of steel.

I'm with the others on the Giessle recommendations. I've got them on two of my rifles and they're money. A little spendier than an RRA, but worth it IMO. Instead of the DPMS LPK, I would go with an LPK from Daniel Defense, their stuff is trust-your-life-with-it bomb proof. You've made no reference to what sort of receiver extension you're thinking about - Carbine or rifle length. This decision will drive the type of buffer/buffer spring you use. As for tools, for what you're planning, common tools will work. The only AR specific tool you'll need is an AR10-sized combo wrench. Also, if you don't own a set of punches, I'd get one. With a DPMS lower, you really have a wide variety of upper receiver assemblies to choose from. Bear in mind that with a DPMS lower Armalite, Noveske, and RRA uppers are off the table; they will not work with your lower. The third leg of the accuracy triad, in addition to barrel and trigger, is ammo. You can't go into a competition with 1970's era Chilean surplus and expect to punch the x-ring. Experiment some and find out what load your rifle likes best. Good places to start are Federal 168 gr Gold Medal Match, Hornady 168/175 gr HPBT Match, and Black Hills 168/175 HPBT Match. Also, what's your budget for optics?

Welcome to the site.

Welcome to the site. Don't y'all have to have a "bullet button" on your ARs out there in CA?

What he said.

No worries, it's happened to all of us at some point or another, I would imagine. At least it gives you the "need" to go back to the range instead of working off items from the Honey-do list.

Well bought and nicely done.

That IS unusual. I recommend you quit your job and start playing the lottery...Or come with me on my next trip to Vegas.

Good lookin' stick. What sort of scope and mount do you have there?

No, it means you have too much time on your hands. Kinda like those folks at arf.com with 5 or 6K post counts.

The short answer is yes, there's a HUGE difference. The build quality of a LaRue, ADM et al, is substantially better than a comparable ARMS mount. When I lock down a QD lever on a LaRue mount, I know it's going to stay locked and not walk itself loose like an ARMS mount. I know the screw threads aren't going to strip out the first time I tighten a screw in it. I know the QD lever will actually lock down to hold the (in my case) RDS in place. My experiences are a data point of one. But if you take a look at some other forums, I am not alone in my experiences with ARMS products. I'm the first to give credit where credit is due, and if it weren't for ARMS and some other companies that stayed in business providing aftermarket parts during The Ban, we wouldn't be having this debate over different mounts. But right now, there are too many better options out there.

Sweet rig. Shot it yet?
