Regarding my pervious review, although I'm not running a sling on the shockwave, I added a sling swivel on the end. this solved the snagging problem I previously complained about- the swivel loop blocks the spanner slots and proves to be a good solution - that said, - I like this thing and recommend it.

I was looking for a way to protect the threads in the mesa adapter. I have the adapter on a mossberg shockwave to accommodate an AR style grip. The plug does not sit exactly flush in the adapter, which is only an aesthetic issue, but the real issue is accessing the safety on the top of the receiver. As you slide your had over the plug to get to the safety, the slots that are cut into the plug to accommodate the spanner are pretty sharp and can potentially cut the web of the hand. A smooth hand tightened plug would have been better, don't really see the need to attach a sling to the plug because there are two attachment point on either side of the mesa adapter. that said there is really no need to use a spanner to tighten the plug and no need for the slots.

With pistol braces in limbo, I replaced the pistol brace with a plug as the 870 was still 26 inches tip to tip. Ordered the plug and received it 7 days later. As the pistol grip was Mesa Tactical it was a perfect fit. Only issue in all the advertisement photographs the plug contains a sling ring. I received the plug and a nice sticker but no ring for the sling. It was not attached to the plug or loose in the packaging. Should you purchase this plug for the Mesa Tactical 870 pistol grip, you will also need to purchase the ring for the sling. I ordered one off Amazon for 3.00 and it fit perfectly. In summary, I am happy with the ordering process, the time of delivery and the plug its self. Just expected it to come with a sling ring as every picture has one included.
