These booster assemblies install in your suppressor to allow the use of BPISTIN pattern booster pistons, which includes:
-All ECCO Machine booster pistons
-All SilencerCo booster pistons
-All Kaw Valley Precision booster pistons
-Rugged Obsidian 9 & 45 booster pistons
-Dead Air Odessa booster pistons
-OSS Rad 9 & 45 booster pistons
-Current YHM booster assembly pistons
-Griffin Cam Lok or EZ Lok pistons for SilencerCo/Rugged pattern
They are also female threaded for Alpha pattern accessories, including Griffin Cam Lok 1.125-28 Direct Thread adapter, Griffin Plan A Alpha, SilencerCo AC2447 & AC2448 3 lug adapters, SilencerCo ASR Alpha, SilencerCo (Alpha) Harvester 300 Direct thread adapters, Q Plan B Alpha and others.
The housings are made from 17-4 H900 stainless steel, the retainer caps are 6Al-4V Gr. 5 titanium. Piston weights vary, but total weight with piston & spring installed will be ~3.3-3.8 ounces (D-Cell assembly is 4.5-4.8, depending on piston).
The AAC TiRant Alpha booster assembly requires the suppressor to be sent in for the retrofit due to the OEM booster housing being a silencer part. The original housing cannot be returned and must be destroyed. Price shown includes the retrofit service, shipping is additional. Alternately, we can ship a TiRant booster assembly to your local SOT or gunsmith for $140 to handle the replacement for you locally if you do not wish to ship your silencer. Contact us if you would like to upgrade your TiRant booster.
These assemblies include booster housing, retainer with O-ring, and spring. They DO NOT include a piston, but you can add a piston in the drop down here: https://www.eccomachine.net/product/booster-pistons/
Though we sometimes have SOCOM black assemblies on hand, expect color options to add 5-10 business days to ship time.
Natural 17-4 H900, Burnt Bronze, Coyote Brown, Tan FDE, SOCOM Black, Grey-Black Colt Flat, OD Green, Flat Brown

Machining is beautiful and refinishing is pristine. Fitment is excellent. These are top notch folks to deal with. Had to contact them to make a minor change and was promptly replied to within 24 hrs with great communication. Lovely experience with ECCO. Will have no issues doing business with them in the future.

Like the previous reviewer, I’m a hobby machinist, also like him I’m blown away at the quality. It’s absolutely amazing what a discriminating master machinist can produce.
The personal attention I received about some questions I had as well as the timely manner, great packaging and gummi bears in the box (personal touch) made this an excellent experience. I’m looking forward to dealing with ECCO machine again

I have purchased 3 booster assemblies from Ecco machine. As a novice machinist myself, I’m blown away by the quality of these parts. Fit and finish is more like artwork. All threads are perfect. Zero play. All edges are chamfered and deburred with laser precision. The spring and piston fit is amazing. I run these boosters on various 1911’s glocks, FNX and others. They function on them all, between them all flawlessly. Also these assemblies are very low profile. If you want a serious quAlity item, that’s a piece of art as well, look no further.
