Re: spikes lower captured spring question

not exactly what you wanted, but it should of come with the screw...and you can run without it, I do and have no problems..pointless when the grip retains the safety spring.

Could of been Seekins that didn't throw it in there, thats who makes them. I recieved my IRMT-R upper last week and it was missing the titanium barrel nut. A quick call to seekins should get you fixed up. Still waiting on my barrel nut but I only called them wed of last week.

Re: spikes lower captured spring question

Your talking about the rear takedown pin right? If so they are all threaded. Mine are anyway. Tactical Innovatins sends a screw with the lower.

Re: spikes lower captured spring question

What screw?

Insert detent, insert spring, screw in the receiver extension (that has castle nut and receiver plate already installed) until buffer retainer is held in position. Piece of cake.

The seekins lower captures diffrently, it's located on the bottom where the pistol grip attaches like the safety spring.

Re: spikes lower captured spring question

I was confused on where we got Seekins from in the first place. Wild Bill, I didn't know they were constructed that way either. Thanks for the info.

    4-40 is correct. FYI Spikes and Aero Precision are two brands of lower that come threaded for the "takedown detent spring mod" from the factory. There may be others but those are two I have personal experience with.

    If you're gonna do the mod make sure you cut down the detent spring by the length of the set screw (1/8") or the takedown pin will bind.
