MAPLE RIDGE ARMOURY - Setting The Record Straight

The MRA Renegade and Maverick work extremely well with PMC ammunition. In fact, all MRA rifles are test fired at the factory with PMC ammo. With that said, the Renegade and Maverick do require a break in period of 10-20 rounds to get the action running smoothly. The first few rounds through each rifle may have a difficult extraction but once the rifle is broken in everything is smooth.

We have experienced very hard extraction with Hornady ammo and military surplus. We think the Hornady brass may not have as much spring back as other brands. In this way, the spent brass case seems to stick to the chamber walls after firing making for a hard extraction. Also, the Renegade and Maverick will not cycle steel cased or laquered case ammo.

If you are experiencing issues with ammo after the break-in period, shoot us an email and we can help work through the issue. Of course all MRA products come with our transferable lifetime warranty all handled directly by us here in Canada.
I just finished a 22ARC MRA Renegade build and am having extraction issues on very light loads. (Hornady brass) I just started some test loads at the very low end of Hornadys load data and already noticed sticky extractions. May need to look at other brass.

Any chance of a pump action in the future?

I'm wondering this as well. I don't like the way the Taipan is setup. No user serviceable barrel, no AR buffer tube for an adjustable LOP, etc. I think an MRA Renegade pump would be a huge hit for more of a run and gun rapid fire rifle to compliment the straight pull version.

Anyone for a 12.5" Renegade pump? Take my money.

You say hard extraction with military surplus ammo.

Do you think it would work with IVI Brass surplus 556 ammo, if I installed a Colt chrome lined barrel and chamber (that worked fine with this ammo on my AR) on one of your receiver kits?

Cheers

One thing that I didn't see mentioned anywhere, by anyone, is that the Renegade comes equipped with that little adjustment screw to eliminate the wobble between the upper and lower. That was a nice surprise.

Actually, after doing some research, I think a forward mounted charging handle would be a much more reliable option than the pump action.

Most pump action rifles have a spring assisted action, which means you kind of have to let the pump go, for it to feed properly / reliably. So it is not the same feel as cycling a pump action shotgun which is kind of the point.

A side forward mounted charging handle would just be more ergonomic, as you still retain control with your pistol grip and still would be the fastest you could go while also being the most reliable.

I own a taipan and yes the cleaning process could have been done better and not require you to undo a lot of screws, but being pump action should go a long time before you need to clean the receiver
 
Another data point on PMC ammo. I just came back from the range after shooting my Renegade for the first time. I used PMC X-Tac 5.56 NATO 55 grain FMJ-BT. I did not have any issues with the ammo although the pmag that came with the Renegade wouldn't seat properly unless I diligently smacked it into place. It still wouldn't click in that case, but would successfully feed ammo into the receiver. Without ammo, it easily clicks into place. So it probably just needs to be broken in. I have 2 other brand new Magpul Gen M3 pmags that worked flawlessly though.
I have a conversion using Ruger parts. With most mags it's difficult to seat when fully loaded. I often just pull the bolt back while inserting a full mag.

I've never had a feed or extraction problem using various brands of bulk 223 or 556, but I've never tried surplus ammo.
 
Ok ill keep breaking it in. So far I'm only at 40 rounds. PMC groups well but 1 in 5 rounds I have to pull back the charging handle VERY hard to extract the case after firing.
This is unsual, the rifle should be broekn in by now. You can try to run a couple more boxes to see if it improves or we can bring it in to the shop for warranty service.
 
I've heard claims that bore snakes are evil because pulling them through at any angle will cause wear to the muzzle crown and harm accuracy. Not certain whether to believe that, but it does occur to me that with a muzzle brake as most Renegades are probably already wearing, that will keep the snake straight that little extra distance and protect the crown and any wear on the front of the brake should be less critical.
An occasional cotton and brass bore snake run chamber to muzzle will not damaged the hardened steel bore or crown.

We have no idea why our rifles do not like Hornady ammo. All Hornady ammo seems to stick in our chambers. I am guessing it must be something to do with the brass. The Renegade and Maverick run well with PMC, Federal, Barnes, Nosler, and Remington from our experience.

Weird. That has not been my experience at all - I have multiple boxes of Hornady "training" ammo through mine without a single issue. I use it because it's basically the cheapest normal option at Bass Pro (the red box stuff at $49.99 for 50 rnds). Otherwise I have used PMC and no issues there either.

The intresting part is, I'm running a 22ARC barrel & bolt from Faxon. It's not an MRA barrel. But I'll try find other ammo than Hornady, it's a bit challenging with 22ARC, seems Ike no one else makes it.
 
"One thing that I didn't see mentioned anywhere, by anyone, is that the Renegade comes equipped with that little adjustment screw to eliminate the wobble between the upper and lower. That was a nice surprise."

I found a solution that works much better than the screw.
Some two sided foam tape (from Dollarama) along the mating surfaces.
Absolutely rock solid. Zero wobble and zero gap now.
