Decided to get my Colt 9mm bolt ramped after 15 year of use. Only reason is I want to use a Geissele SSA trigger. So I hear all the great reviews about ADCO. I called them and just got a voice mail stating best way to reach them is by email. Sent them a simple email as to whether or not the ramping would be compatible with the SSA trigger and no response. Decided to just ordered their ramping service for $50.00. After placing the order got a notice I would get an order conformation email along with a form to sign credit card authorization as it is a shop service. Never got the email. Good news is my credit card was never charged. Waited a week, maybe they were having some technical issues. Tried to order the service again tonight and same thing. Stupid me for trying to order a 2nd time. I guess they are doing so well they don't care about new business. Pretty much gave up on them. Their website sucks as well. Sorry for the rant.

Anyways, does any know of any other place that can do the ramping?

I had two 9MM bolts ramped by MGP. One was a Colt, the other was Rock River. My Colt 6450 has the large hammer and trigger pins. I used a JP Enterprises large pin Speed hammer to make it all work.

Just want to say thanks to Rudy - Mad-Machinist. I got my ramped bolt back in 1 week. I slapped a lower with a ALG ACT trigger group and it works. Haven't taken it to the range yet, but it feels a lot nicer then the current dedicated 9mm hammer and trigger. Can't wait to get the SSA-E trigger installed on my DDLES lower.

Mad-Machinist ramped my PSA bolt this week too. I haven't shot it yet but it looks very nice.

However, it is important to note that they are still shipping unramped bolts. And they are unapologetic about it.

This is what I was planning on:
http://palmettostatearmory.com/index.php/ar-9-ar-47/ar-9/psa-10-5-9mm-1-10-melonite-upper-with-bolt-and-charging-handle.html

Specs:

SKU: 507961

UPC: 507961

MFR#:


Barrel Length: 10.5"
Barrel Steel: Chrome moly
Chamber: 9mm (9x19)
Twist: 1 in 10"
Barrel Finish: Melonite treated
Gas Block Diameter: .750"
F-marked front sight base with shaved bayonet lug
Flash hider
7075-T6 A3 AR upper
T-marks
9mm Bolt
Charging Handle


I assume that's the $95 regular bolt, not the $170 ramped bolt.

ETA: So total in the project will be
$310- Complete CMMG pistol lower
$300- complete PSA upper
~$40 Rear sight
~$27 PSA or other magazines.

Be careful, varies by part # it seems - both the 4th of July 9mm "deals" include "NOT ramped" bolt.

What's the advantage of the ramped bolt?

Got a Geissele G2S trigger from Primary Arms recent sale. Could not justify the price for the SSA. Trigger is installed on my DDLES dedicated 9mm lower. Went to the local indoor range today and put 150 rounds through it. All I can say is "Wow" this thing rocks! I have been missing out all these years. Never really understood the Geissele fan boys till now. The trigger is very predictable. All my targets turned into a 2-3in ragged hole at 25 yards (max indoor distance). This was just standing and shooting off hand. Another benefit I noticed with the ramp bolt is that charging the gun is lighter and took less effort than it was before.
