The term “integrally suppressed” is becoming more and more popular in the rifle world. The Daniel Defense DDM4ISR is one of the more intriguing entries thus far.

Tax Stamp

Chambered in .300 Blackout, the rifle features a 9-inch cold hammer forged barrel with a permanently welded suppressor. The suppressor is approximately 10 inches in length. The rifle is a one tax stamp gun, for the suppressor only. Since the integral suppressor extends the barrel to an NFA-required 16 inches in length, it is not considered an SBR.

“It’s not classified as an SBR, which is handy, so you only have to pay the $200 tax stamp once on it,” says Thomas Carlson, Daniel Defense’s Director of Marketing Communications.

DDM4ISR: Beyond Quiet

Another impressive feature is the noise, or lack thereof. The rifle shoots sub-120 dB when firing subsonic ammo. The silence was quite impressive out on the range when the “ping” of steel was noticeably loud than any rounds leaving the rifle

“It’s super fun to shoot,” Carlson says. “Since it’s a low-pressure round, the suppressor doesn’t get very hot either.”

MSRP on the DDM4ISR is $3,198.
