    Hey guys, I got a Mossberg 702 Plinkster 22LR this past Friday and need some help with it. I mounted a Tasco 3-9x50mm with see-through scope rings.

    I'm looking for a way to mount a bipod as my next modification. I've got it grouping quite accurately at 15 yards, but need a bipod for the rest of the accuracy to increase. I know it's "just" a 22LR, but I want tiny groups at 110yds. Anyway, the 702 Plinkster doesn't have a swivel mount thing so I can't easily mount a bipod. I DO have a Winchester $40 bipod from Walmart, I just don't have a mounting point. Any ideas?

    Something like the stud on the left in the pic below. You'll have to drill a hole in your stock and probably trim the threads down to keep it from hitting your barrel. You may also have to reinforce the stock to keep it from touching the barrel when the bi-pod is used, the synthetic stocks tend to flex a bit.

    Or something like the barrel band stud mount below. You'll need to measure your barrel to get the right size, I recommend using a dial caliper for the measurement. But this will also cause the barrel to flex while using the bi-pod.

    Eric 0424's advise is right on the money. Just install a front sling swivel stud.

    I was warned that doing so would crack the stock to no end. I have the first option (installing a stud into the stock) readily available. Well, Winchester has a version of it that WalMart sells. Which one should I get:

    I really couldn't say, I would have to actually see the parts with the Winchester kits. The descriptions don't have enough detail on the individual studs. One of them with a machine threaded stud and the nut to match should work.

    Unless Mossberg has changed the Mossberg 702 Plinkster it's going to have a plastic stock (my understanding is that it's really plastic not the higher quality polymer). That might be the reason you heard about cracking, What I would do is drill it out first and slowly move up bits till it's close to swivel stud size, then screw it in and secure it with some glue.

    loaf_fan, I can definitely see it being the cheaper plastic. In all actuality, polymer=plastic...but yes, this is the cheap stuff. If I have to step up between sizes, I can make it happen. However, do you think it'll ruin the stock? I'm sure it's NOT a cheap part. I have a lot of experience working with things like this, but I'll have to try if you think it's doable.

    Eric, the kits DO have machine bolts and nuts in them. Could it be as simple as drill with care, cut off excess, tighten nut, install bipod?

    Yep, installation should be as you described. If the stock seems thin or weak in the stud area you may be able to reinforce it to help spread the load, but I haven't been able to see what the stock looks or feels like on the 702.

    Eric, I got the gun for under $100 NIB from Dick's....so I wasn't expecting much. I'm pleasantly surprised, but in no way am I thoroughly impressed by the quality. I'll play around with it and get back to you guys.

    Quick question, though...about how much would a replacement stock be?

    You'll probably have to go directly to Mossberg International for parts. The usual places I buy parts from don't carry anything for the 702 other than the magazines. A friend of mine owned one the these for a while, it was a good rifle. It didn't blow us away with fit and finish, but it was an accurate rifle and never gave him any trouble. They're well worth the $100 asking price.

    You have a couple of options on the stock. The first, if you want to go back to a higher quality wood stock you need to hunt up a stock for a Magtech 7022 (yes the ammo makers). Same as the Mossberg 702, but with a wood stock. Another option is to get an ATI stock for a Marlin 60 and dremel it out -- Never heard of this before stumbing on it today. See:

    any other stock options for a mossberg 702?

    As far as ruining the stock, as cheap made as it is, any modification I think might give you the chance to ruin it. I'm tempted to try out the Marlin ATI stock. This rifle, as cheap as it is, is still pretty darn fun and suprisingly accurate for the price.

    Well guys, I added the scope today. I went to Walmart, they weren't machine screws AND they wanted $9+tax....so I went to my local Army Surplus. They had one for $1.50. I said, "Thanks," and ran. At home, drilling took 5 minutes and showed no signs of stressing the plastic. i think it's too soft and giving to try to crack. It looks great, and works great. Only problem is I mounted it about 1/16" too far to one side :mad: and it gives me an uneven lay at full extension, so I have to shorten one ever so slightly. Either way, I was getting groups of about an inch at 15 yards. My GF and I are both bad shots, and we had 28 of 30 rounds in about a 1" diameter bullseye. I still have sighting in to do at 100yds, but I was getting groups of about 4" with Federal Bulk Pack stuff, and I'm sure using CCI would help it.

    One thing I did do was used a grommet I picked up at the hardware store for a couple of cents. I cut it in half and used it as a washer on the inside between the nut and the stock. Really made the mount sturdy and didn't worry me at all. Also, I didn't have to shorten the bolt at all because of the way the inside of the stock is designed.

    Glad you got it done. Now you can fine tune your shooting form and experiment with different loads to attain better accuracy.

    Not that anyone's following this anymore, but for people browsing....the sights are pretty much dead on. I mean, they might be a couple of clicks off, but I'm getting tiny little groups. My girlfriend put ten straight (with little effort) through an empty quart of milk at 110yds in quick succession. I'm VERY impressed and VERY pleased.

    Only thing it's doing is the bolt was sticking the last time we were out. Of about 200rds through it, the bolt got stuck (had to disassemble once) three times. Really annoying, but I'm wondering if that had something to do with how I cleaned/reassembled it.

    Clean and lube it

    Spray it with Breakfree CLP and work the bolt, wipe it off/out, and spray it a little more, finally wiping excess off and should smooth out and not stick anymore. I've gotten to where I don't even take it all the way apart anymore just the above mentioned and it works wonderfully.

    On a side note, it's wonderful how accurate a rifle you can get for a $100 bucks (in my case it was $86 OTD) isn't it?

    I just sprayed remoil ALL over the bolt and brushed furiously with a toothbrush and plastic 9mm brush and I think it should be okay. It had never done it before, but I'll be able to tell if that did it or not by Sunday night (I hope).

    But yeah, the accuracy is incredible! Especially since I firmly believe that the size of the groups at 110yds with a 22LR is more limited by ammo quality and my finger than the gun itself. I've got a buddy that shoots pretty seriously, and I think he'll be the best chance I've got of seeing how well it shoots in the hands of someone who knows what they're doing.

    One last point, I don't know if it's gun or ammo....but shooting Federal Bulk with this gun, the drop at 100yds is not nearly as bad as the drop at 110yds. At 110 I can hit anything I want, but at 100yds I'm lucky to get close.

    I have an 802 Plinkster, i installed a barrell mount(clamp on) bipod works excellent. i also installed a sling, if you use the machine screws with the nut, drill a 3/16 hole and the screw will fit perfectly, you almost dont need the nut.[​IMG]

    The wife and i can get 10 shot quarter sized groups at 50 yards, haven't tried any farther.
