Question concerning Rock River 22LR mags

[happygeek]

The wife got a Rock River Arms LAR15 with a 22LR upper awhile back. It had all sorts of issues at first: failure to chamber, failure to extract, the bolt carrier came off the charging handle twice, etc. but the store sent it back to Rock River for us. We just got it back and I took it out to the range yesterday. Fired about 90 rounds with only one failure to chamber, so

It's good cheap fun being a 22LR, problem is it only came with one 20 something round mag. The store we bought from has them on back order and still has not gotten any in. I've been Googling around looking for some online and so far only found this: https://www.gilbertsguns.com/Rifles/Colt/Colt+M4+22+LR+30+Round+Magazine

My questions are will these work in a Rock River 22 and has anyone bought from this site before and has comments on if they're a good store?

Those will not work. They are for the Walther/Umarex/Colt dedicated AR-style .22.

The exact magazine that you will need is dependant on the exact upper/conversion that you have. Chances are, Black Dog Machine makes what you need.

Thanks, I just ordered a 15 round and a 26 round mag from them. I'll try both and order more if they work.

Just posting to say thanks for the link! Their mags worked great.
