My Disruptor FRT in my 16” middy with an A2 rifle stock and buffer worked perfectly from day one. No tuning required and absolutely no issues.

I'm at 1,400+ rounds, zero manfunctions.  About 400 of those were in semi auto, 1000+ were fast semi.  During the most recent inspection there is zero visible wear other than the sear polishing in and the semi auto pull getting silky smooth.

Installed a Disruptor in my brother's PSA 10.5" pistol for him. Used an H-3 buffer and the stock buffer spring. 55gn PMC bronze. Worked perfectly in semi and FRT mode. No failure to feeds & bolt locked back on empty mags everytime.

Well I'm going to have to tear one of my disruptors completely down for a cleaning I think!

I've put 2-3,000 rounds of 9mm through it and I'm getting FRT on semi & FRT positions.  I'm assuming something is dirty even after a basic cleaning, and a function check doesn't show any problems, only live fire.

When did you get yours?
I got mine in May and it started doing that after a very few rounds.

Apparently the safety lever was redesigned with a deeper cut.
I had to get a new one for the Disruptor and for the Rare Breed.

It's one of the early batch ones with the crappy/no-detent positions on the safety.

I emailed a long time ago about the safety detents but never got a response and things were busy so I've just been running it.


I'm not actually sure when it started running FRT in semi; it spends most of it's time in position 3.  The malfunction could have begun many rounds ago without being noticed easily.

Second the question. While the usual suspects (AKM, RPK, -74 variants) are of great interest to me, my R5 clone would be … intrigued.

Ok, LAT received.

Installed the Datum Machine pin capture bushings easily.

Able to install safety with the trigger pin out, then install pin.

Unable to fully close the upper and lower. Hammer is cocked.

I know there’s a trick to pulling the charging handle to allow clearance, but this seems moot as I can’t close the upper.

Upper is probably Brownells C7 on an 80% forged lower. Have completed these previously with 5D jig and drill press with no prior issues.

@SSG-69

With most of my guns, you can close the upper down onto the lower and pull back on the charging handle. It may take a little "force," but it works on all of my guns.

Or you can keep the front takedown pin in the upper, drop the hammer, and swing the upper down onto the lower.

Do the rear pin first, don't do the front pin til after. Rock the upper ever so slightly upwards while gently pulling back the charging handle and the rear should seat. Then do the front pin.

Try hammer un-cocked, front pin in first then rotate close. Pull charging handle a little and the upper will drop far enough to close the rear pin.

"We’re pleased that the Federal Circuit has now confirmed what we believed all along.  Judge Rankin of the District of Wyoming was correct in denying Rare Breed’s motion for TRO and PI, and no injunction should issue against the sale of Peak’s Disruptor triggers.



Rare Breed failed to show irreparable harm from the Disruptor sales, failed to show a reasonable likelihood of success on its infringement claim, failed to rebut the substantial question of invalidity as to its patents, and failed to show that the public interest or balance of equities favor an injunction.



We look forward to continuing to defend Peak’s rights as the cases move forward.”

In b4 mod smackdown for general discussion.

It means RB's attempt to clear Triggered from doing business while the case is decided failed.  Triggered's doors remain open.

Nothing more.  RBs infringement case lost a lot of hot air, and Triggered continues to sell while they defend against RBs intellectual property infringement claims.  Hoffman was not so fortunate when he was barred from selling his own invention 'cause RB bought rights from a false patent holder.

@Ben:

This was the only technique that worked for assembly. However, the bolt carrier will not completely retract; the front of bolt, i.e. lugs, are parallel with the rear of the ejection port spring- not far enough to feed a round  from the magazine.

Safety function, trigger reset functions correctly.

A2 forged lower with rifle extension, spring, buffer, pretty vanilla setup. Surplus full auto milspec BCG.

consolidated replies:
@TOTHEMAX:  “With most of my guns, you can close the upper down onto the lower and pull back on the charging handle. It may take a little "force," but it works on all of my guns.”

- - Bolt carrier not clearing top of lower receiver. Whether I put the muzzle down and squish against me or just use hand strength, there remains a fishing line width gap and the takedown pin boss hole is not lining up with the takedown pin in the lower by the same fraction.

“Or you can keep the front takedown pin in the upper, drop the hammer, and swing the upper down onto the lower.”

- - No difference. I also removed the trigger assembly and with it out, lower closes normally without problems.

Here you go. As an aside, I’ve made “more than one” lower over the years, paying attention to jig tightness and wear and tool head wear. There’s a single careless tool chatter from the router near the bolt stop, an area that has no impact on this. And assembled “more than one” factory lower. This problem is novel to me. So, lower could be out of spec/stacking tolerances, but it seems fine absent the LAT. I will try the trigger in other lowers (homemade, known good factory), with another upper, and with other bolt carriers tonight.

Both pins in, holding back the charging handle to max. I did not try to mortar it; it’s caught on something:

Position of top of LAT:

Attached File


Appear to be marks on lower 1/2 of hammer, closer to pin. Carrier drag? contact?

Bolt carrier is new; ramp on underside of carrier. Striations may be drag wear from hammer. I examined another carrier from same batch on upper which has not been on a lower yet, and marks not present.

It definitely could be slight out of spec tolerances with your lower.

If you have another mil spec lower I would drop the lat in it and see what it does with that upper.

So, lower could be out of spec/stacking tolerances, but it seems fine absent the LAT. I will try the trigger in other lowers (homemade, known good factory), with another upper, and with other bolt carriers tonight.

Both pins in, holding back the charging handle to max. I did not try to mortar it; it’s caught on something:
