I've seen pictures where people have no buffer tube on a .22 AR pistol. What do they use for a back plate to keep the bolt assembly from sliding out the rear of the receiver?

Hey, quick question. Doesn't it need some kind of back plate as well to hold in the spring and detent pin for the takedown pin?

My Spikes Tactical pistol lower has a threaded hole and set screw to hold the rear takedown spring and detent in place.

This is interesting. I just got my Spike pistol lower last week and mine is not threaded and doesn't have a set screw. I will have to use one of the carbine style plates.

I think that the reason that it was threaded and a set screw installed was that it had the short buffertube installed on it. It did not have the backplate.

We have a new 22lr pistol plug (not on our site yet) with a QD socket in the rear of it. Its $50 and comes with an Uncle Mikes Heavy Duty QD Sling Attachment.


We drill and tap all lowers we assemble. So if you got a stripped lower it wont be done like that.

IIRC, all you need is a 4/40 tap, a little oil and go slow. Theading completed in about 2 minutes or less.

Let me check my stash and see if I have a couple...if I do, you can have them.

ETA-I have 3 of them. 2 are long ones and the third I cut to the same size I have in my pistol lower. If you don't like the one I cut or just want to cut your own, you can use a Dremel tool and a small cut off wheel and cut them yourself.

IM me your addy and I get them out tomorrow.

The longer ones should be ok if you cut the spring alittle shorter.

Should I tap the complete length of the hole or just enough for the head of set screw to be recessed a little?

It will not hurt if you thread up to half-way of the depth of the hole...just make sure you clean out the shavings.

badazzar15 can give you a more definite answer on how they do it at Spikes when they build one..

I am wondering if it would be a problem to use a sling adaptor either A2 or carbine style with the spikes plug? I have the 22lr pistol upper that is on their website on order.

We tap about 1/2" in, No reason the tap the entire whole.

Here is the New Plug we offer.
