I bought a 715T this morning and was fortunate to discover MidwayUSA has the 25-round magazines, so I bought two (the limit).
Watching the videos of the disassembly/reassembly I'm very concerned about proper takedown but I own a 25-year old Ruger Mark II and think if I can reassemble that the Mossberg shouldn't be too much more difficult.
Any tips will be appreciated, and looking forward to getting my new 715T prepped correctly so that I can enjoy years of fun.
I thought it was time for a review of my new 715T, so I hope readers are interested.
After I bought the handle version I became very concerned that I had made a mistake even before shooting it. When I watched the disassembly/assembly video I understood that all AR-style .22lr rifles aren't designed alike, and not being mechanically inclined I figured I'd really stepped into it. Next was the ammo situation, where like so many others I couldn't find any .22lr ammo for weeks.
Next was the weather, which was unseasonably cold and nasty, and finally my daughter's car needed repair and I was going to sell the NIB 715T unfired if possible.
Well, I found some ammo, the weather cleared up, and I found the finances to fix the car so I decided to shoot the gun. I had been patient with the two 25-round magazines I bought the same day I bought the rifle and let them sit for a couple of weeks fully loaded. Yes, they can be tricky but patience and persistence taught me I don't need to disassemble or oil them; switching back and forth from handloading and the tool allowed me to load-empty-reload several times prior to shooting.
At the initial range break-in I primarily shot bulk pack Federal in the 550-round box, which has always been the best cheap .22lr ammo for my Ruger Mark II. I had a number of FTF, FTE, and duds with this ammo, so I tried a 50-round box of Winchester X, with the same results. I then went to a 100-round box of Winchester Super X and the results were somewhat better but overall I was disappointed that things hadn't gone as well as I hoped. I finally ended the session by shooting the two remaining 50-round boxes of the Winchester X and was surprised that the hundred rounds went off with only a couple of hitches. The 10-round magazine shot every ammo without difficulty, adding to my concerns that there's a design problem with the hi-cap mags.
I came home, watched the disassembly/assembly video again, then set about cleaning the gun with a lot of anxiety. It didn't take long to disassemble but cleaning was a real chore because I like to be as thorough as possible. I was pleased that putting it back together wasn't as difficult as I imagined, except getting the bolt/trigger assembly back into place took quite a while. Again, patience and persistence won the day. I was concerned that I had forgotten to take the toothbrush/solvent to the extractor and hoped this wouldn't create a problem on the second range visit.
Last night I found some bulk pack Golden Bullet ammo --- the worst-performing ammo I've ever used in my Mark II --- and took it and the rifle to the range this afternoon. The weather was dreary but warm enough, and I was the only one at the outdoor range. This time I decided to only shoot the 25-round magazines and I am pleased to report that in the two hundred rounds of Golden Bullet I fired I only suffered a single incident where a spent casing got caught in the bolt during ejection. The last two magazines were fired as fast as I could pull the trigger. What a hoot! To say I'm extremely optimistic at this point is an understatement. I went to the range expecting to shoot at least three hundred rounds but decided to save the 325 rounds I have left. My thought was to come back, thoroughly clean the gun, and hope I can find more ammo before shooting it again.
I thoroughly cleaned the rifle but again the bolt/trigger reassembly is a bitch for me to get done; but this time I remembered to take the toothbrush to the extractor with solvent. It took me about two hours to disassemble/clean/reassemble the rifle but since my hopes are high I don't really mind.
I had thought I should have bought a different AR-style gun, but with my increasing optimism with the 715T the difference in price adds up to a whole lot of .22lr ammunition, and I know the other AR-style rifles can be just as tempermental as Mossberg when it comes to ammo and function. The next time out I hope to shoot a ton of ammo and once I'm totally confident I plan on shooting this rifle as often as I can. It's really a whole lot of fun at a reasonable cost.
So for anyone who has the same concerns as I did, I recommend patience and persistence and with a little luck in a short time you might be where I am now in the 715T experience. If you feel comfortable with breaking down the new gun and cleaning it before firing it I strongly suggest doing that as I now suspect the factory gunk may very well have caused my initial range outing problems.
