THESE P SERIES KITS INCLUDE ADJUSTABLE, CONCEALABLE, GAS BLOCK PISTON CONVERSION KITS AND REPLACE THE EARLIER XLP (P Series is 30% lighter with enhanced locking lugs to better secure the gas plug). Kits are designed to retrofit a direct gas impingement system (i.e. upper with a gas tube) and change it to a clean running, ultra reliable, piston system. Base Kits DO NOT INCLUDE BOLT/FIRING PIN/CAM PIN BUT MAY BE UPGRADED FOR ADDED COST WITH OPTION). UNLESS A BOLT COMPLETION KIT IS ADDED, THE BCG AND RIFLE PICS ARE FOR EXAMPLE ONLY OF COMPLETED BUILDS.

Installation Instruction Card
NOTE: ADAMS HAS DISCONTINUED SENDING RECEIVER BUSHING AND INSTALL TOOL AS THESE WERE DEEMED UNNECESSARY FOR PROPER SUPPORT.
The Adams Arms Piston System:
A short stroke free floating piston system.
Carbon and gases are expelled forward, away from operator.
Corrosive resistant coating processes.
Harmonics are not transferred into the barrel.
Doesn't vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fire.
Has a Lifetime Warranty.
To select the correct length kit, use the following measurements:
Pistol: 4.846" from barrel extension to shoulder PK-MICRO-ADJ-P FGAA-03217
Carbine: 7.866" from barrel extension to shoulder PK-MICRO-ADJ-C FGAA-03203
Mid: 9.866" from barrel extension to shoulder PK-MICRO-ADJ-M FGAA-03206
Rifle: 13.241" from barrel extension to shoulder PK-MICRO-ADJ-R FGAA-03220
300BLK (We only recommend a Pistol Gas Length and a Low Mass Carrier for optimal performance) PK-MICRO-ADJ-300BLK FGAA-03300
We recommend using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.
Micro Gas Blocks should have the set screws torqued to 87 in-lbs
