Are these plugs necessary or maybe just a good idea to add to your buffer to help prevent wear to your lower as the maker claims?
You folks have them in your lowers? Would a shaped wooden or aluminum dowel accomplish the same function if needed? |

Would a shaped wooden or aluminum dowel accomplish the same function if needed? I made up some Delrin buffer replacers many years ago. They are long enough to stop a standard AR Bolt before a bullet can be allowed to chamber. They work great at keeping FTF's with a 22 bolt to a minimum. TACCOM's Plug is simple and cheap and can even be bought as part of a TACCOM Reliability kit that has an extractor and very good firing pin. I think it's 30 some dollars for a lot of additional reliability. Well worth the money. Dave in Florida |

I made one out of maple and it works fine, I do not have a buffer tube and spring so I use a cap head SS screw threaded into a T-Nut to put pressure on the bolt. If I had a buffer, buffer tube and spring I'd just buy the plug. |

The .22 conversion kit I have is so @#%&!* tight that I had to hammer it out the first dozen times I installed it. Still fits really tight - I've put it in five different 5.56 uppers. No need for nothin' for me. IF it goes in tight....towards the end,.......you need to relieve the grooves on chamber adapter that the rails slip over. I suspect they may have to be deepened by .005/.010 on each side. When they are too shallow, nothing is concentric and it will bind up. I've relieved them in the past with a 1/8" wide wheel on a dremel. I would be willing to bet money that is your problem Tim |

| Thanks for the suggestion. The adapter has tiny, shallow grooves where the barrel extension bolt lugs have cut into it. A firm, positive tug now extracts the adapter from any barrel I've got, so I'm just goiing to leave it as is. Plus, no need for one of those pressure thingies to make or buy and then lose when I take the adapter out to shoot 5.56. |

I can understand that....however...think of this: IF it is binding up (tight).....it is rubbing against something. Eventually, it will be loose as it has worn in. You could be wearing out the upper, the rails or worse....the chamber. Personally, I'd do the fix that I was talking about and run something in the buffer to put pressure up against the back of the insert. Trust me on this.....I'm not trying to sell you anything, just try to help you out.....thats the way I roll. Tim |

Interesting posts you guys, (thanks) I have to look for that when my upper arrives. So I tried my hand at making a pressure plug out of a screwdriver handle and hopefully that will save me about $15 after shipping if I were to have ordered it. ...or put another way, that comes to about 200 rounds of CCI Mini-Mags... Also I need to know if it is normal for the bolt stop to be in the "activated" position when the Better-Mag .22 rimfire adaptor is in place...sure hope so. 
And sorry about the poor picture quality also.
