So, it looks like they kept your gun for over a month and a half, and didn't improve anything. I wonder if they even looked at it? 

This is so sad, and I hope you can return it for a refund. Thank you for giving us a heads-up.

I put a small piece of tape behind the barrel guard if they opened tube it would be gone, it was not.  The barrel breech o-ring was still the one with chunk out of it.  Only the handwritten FPS note was even close to  acceptable but 2 chronographs I own different brands read low power about 23.5 FPE and the chronograph tape Crosman stuck in box read about 23.5 FPE.  Rifle advertised as up to 950 FPS...so obviously they would use the Crosman cheap standard pellet as development pellet 14.3 Grain = 28.7 FPE.  

If they get the power up this would be a tree rat, iguana killing machine

Needless to say I sent this one toward Midway for a refund.

I thought it was awesome. Here is my review video. It was very accurate and tons of fun to shoot. That's all I remember.

If they retune it will be  a heck of a nice rifle.  with .22 at 23.5 FPE the trajectory is sorta a rainbow

New here but not new to airguns...

Sandy Clause done brung me one of those new fangled Mrod semi autos. 

Only 100 shots, initial thoughts are:

Its heavy clunker.  

Looks well built.

Factory target, 5 shots @ 10 yards 😫, Corssman 14.3s, shows zero vertical dispersion with 0.25" horizontal dispersion which equates to no better than 2.5 MOA @ 100 (if it will shoot that far...).

Initial velocity, factory spring setting: 846 FPS (MagnetoSpeed V3 chrono). Single digit ES.  Darn nice, I'd say.

Maxed out spring adjustment.  Got 889 FPS for 3 shots.  All three were 889.  Not as much as anticipated but for the intended use of the rig it could be useful.

First 27 yard, 10 shot group wasn't bad but wasn't great either.  Figured it to be a good start showing promise.

First 100 shots were miserable.  Max attainable velocity.  Max attainable velocity with Crossman Prems is about 820 FPS.  [Flat unacceptable!]

Accuracy is for squat. So bad that shooting holes in snow at 50 yards says a pigeon is pretty much safe.

I'm a long time AirForce Condor SS tinkerer with sub MOA accuracy with 24.8 grain NSA slugs to 195 yards.  This SAMrod is a big step backwards but for up close things with feathers it'll do, if there can be some accuracy.

I'm thinking that the MagnetoSpeed hanging on the end of the barrel will certainly have a negative affect but was trying to see what velocities I could get.

Also, MV varied all over the place to day in the sub freezing weather.

 

I have high hopes for this rig and she'd best live up, or I'll go to tinkering.

We'll see....

The first 140 or so rounds were to get the "rhythm" of things.  Was neither fun nor successful!

After the semi auto is definitely a southern California device.  Today's temp range was from 3 to 25 deg F.  I was in the sunny part with the higher temperature.

Action function miserably.  Velocity spread was 100s of FPS.  Many misfires then when the charging handle was messes with several 2-pellet launches were made.

Max velocity was in the low 800s.

In the pellet stove heated basement, temp 80 degree F, with max hammer spring pressure, velocity was maxed out at 886.  This with Crossman 14.3s.  A long way from the advertised 950 max.

If she can't make at least 920 FPS with Idaho winds, she's practically useless.

It is said that regulator pressure is somewhere around 2030 PSI.  When it reaches about that value things go to hell in a hand basket real quick.  Velocities vary extremely and around 775 FPS with misfires and double shots.

When warmed in the basement and shooting 22 yards out the door accuracy tended to duplicate the factory target.  There were "some" fliers" but she wanted to hold elevation and string 'em left and right.

I'm betting that when magazines become available I'll find some that work better than others both for operability and accuracy.

However the low velocity is a big problem.

From my AirForce Condor SS modification experience there are things that can be done to the SAMrod to improve accuracy but with that low velocity she's way to big of a hunk of wood to lug around and shoot no farther than tree top...

A bull pup stock would be a great enhancement for this rig as ya don't hafta mess with a bolt handle.  But a shield for action gas may be necessary...

So far definitely NOT the info I was hoping to hear. I hope Crosman can work out the issues. 

thank you for the feedback guys!

What good is a SA if the magazines don't work? It is sad to see quite a few AG brands bring unsorted AGs to market with a POS plastic magazine that causes jams and/or negatively affects accuracy. Then they have to deal with the cost of returns, etc. In some cases the initial failures reputation end up killing a promising model line. You can buy two Ruger 10/22s that function as intended for the cost of one trouble ridden SAM. I purchased a NIB $1K Evanix Air Speed that both magazines failed in under 100 shots. Two years later I am still waiting for the "redesigned" replacement mags promised to be shipped promptly to me. I fixed and upgraded the mags in 20 minutes and the gun functions 100% no jams, JSB 18 gr at 900 fps, but accuracy is nothing to brag about. Sorry, did not mean to hijack the thread, just whining about my buyers remorse I guess. However, I still shoot my single shot Falcon FN12 with no failures to feed or even an oring replaced in 15 years and it brings a smile to my face.

Mine cycled well no jams etc.  Power was low and they did not even try to bump up regulator.  When some refurbs show up I will jump on one and get HUMA to make me a larger plenum and use their regulator.  Seems reusing the Field Target Model parts have this rifle power limited in .22.  Not sure if their method of SEMI auto will work outside a narrow pressure window.   If it works at higher pressures then just increasing regulator set point will yield more FPE.  If not then more intense mods for high volume low pressure

Had a good rant going....during which I called customer support....

Got a nice guy on the other end. Was a pleasure to talk with him.

My magazine is "all chewed up" on the inside.  He's sending a new one. 

He had me check for the presence of the O-ring in the breech.  It seems folks are having to run a rod down the barrel to push out a pellet and bump the O-ring out which causes a loss of velocity.

After discussion it may well be that my chewed up magazine may be due to the "spring" slipping internally which causes the damage I see in my magazine.  Which in turn contributes to lower velocity.  He says that when everything is functioning as it should I should expect 900 to 920 fps which is acceptable to this ol man for the pigeon permissions I have.

We'll see....

@critter99 The trade off of the regulator.  Great shot count and consistency with the sacrifice of power.  A standard marauder in 22 I once tuned got 25 fpe with .22 domes for 32 shots.  But a semi gun may be a different animal.

While talking with the Benjamin customer service fella the other day I learned that:

a)  for the most part the Gen 2 magazine will function in the semi auto version, and

b) in several months the older version magazine, the one with the oblong hole will be discontinued with the only magazine available being the new one that comes with the semi auto version.

 

After dismantling the factory semi auto magazine nothing was found that indicating the internal spring had "slipped"...  It would seem to me that the magazine has/had either design or manufacturing problems which caused it to be trashed...

We'll see when the new one(s) arrive.

 

Spent about 8 hours turning a barrel tensioning gizmo for the new semi auto.  It worked perfectly... but... found that the JSB 15.89 Exact Jumbo pellet worked the best of pellets tried.

Replaced the shroud, spring and baffles and tried it.  The 15.89 pellet shoots absolutely fantastic with the factory arrangement.  Will match any airgun I've ever fired for consistency and accuracy.  However, 840 fps is a little on the slow side and shot count is not nearly as good as advertised.

Benjamin customer service pulled though with 2 brand spanking new 22 cal mags for the SAMrod.  And I'll be durned if they both don't work flawlessly.  I really wonder what was wrong with the one that came with the rig.

Grandson-in-law came for this past weekend.  We headed to one of my pigeon permissions with the SAMrod without a clip.

I was the spotter calling dope and fodder feeder (feeding 15.89 gr JSBs with tweezers while he held the charging handle back) and he did the shooting.  Twas quite funny and similar to running a flintlock.  We got the process down pretty good.

Nothing went as planned after the first pigeon at 77 yards.  The flock flew out to a centers-pivot sprinkler at 129 yards and lined up like a shooting gallery.  Wind was pretty decent.  First shot at 129 the shooter watched the pellet be spot on for elevation and about a foot with the wind.  The pellet went between two adjacent pigeons.  The flock flushed and landed down the pivot a ways.

We walked down the wind break and ranged the birds through a break in the wind break at 119 yards.  I call the dope.  When the shooter was on it, I gave the "send it".  The little Marauder went Phtttt.  The shooter shouted that he hit his pigeon.  He couldn't hide his amazement.  The hit was in the back of the bird a big inch up from the base if the tail.  The target bird left with the flock but couldn't maintain speed or altitude.  We watched in big anticipation while it flew about 300 yards into the ground.  About 10 FPE and a poor hit finally got the job done.  We counted it as a kill..

After 5 more consecutive kills from 50 to 85 yards the shooter started getting cocky.  Young fellas will do that...

The next pigeon was broadside at 95 yards and he calls a head shot.  I said yeah...right!?  Phttt goes the SAMrod and the pigeon falls without a flutter.  If there would have been a magazine in the rig he could have poked at least one more as the disturbance out there wasn't immediately noticed by the rest of the flock.  

I've been slaving over an Airforce Condor SS in 22 cal for several years and finally got it down to right around 1/2 MOA out to 195  yards.  My son got an FX Crown in 25 cal that shoots well under MOA at 100 right out of the box.  Since Saturday's hunt we have tested and retested this SA Marauder out to 125 yards and in very still winds 1/4 MOA is typical for as many shots as you want to shoot.  Having said that there are a couple of slots in one of the mags that sends a flier on a regular basis.  I'll diagnose that problem before its all over....

I'm impressed with this little rig.
